Allelopathy generally refers to the inhibitory effects of plant species (the donor) on the germination, growth or development of another plant species (the recipient). Chemicals with allelopathic activity are present in different plant parts including leaves and fruits which have a potential as herbicides. The donor plants release allelochemicals into the environment through decomposition of plant residues, root exudates, leachates and volatilization. Accumulation of more allelochemicals from weeds in fields causes soil sickness and autotoxicity resulting in loss of crop yield. The study has been conducted to examine the allelopathic effects of Celosia argentea L. on seed germination and seedling growth of Vigna mungo.

Senescence in Vigna mungo (L.) Hepper is studied here. The biochemical impact of endogenous hormone inherent in Eucalyptus leaf extract on it was specially studied. The studies were made by taking aqueous extract of dried leaves of Eucalyptus citriodom at various concentrations and compared with control. During study, the various concentrations of Eucalyptus leaf extract taken were W/V - 1:200, 1:250, 1:500 and 1:1000 respectively. Senescence was studied in intact and excised leaves of Vigna mungo (L.) Hepper. Observations were made both in light and dark in species under investigation. The inference drawn out of experimentation are worth noticing. Whether use of dried leaves of Eucalyptus can be done as bio-fertilizer in seedling growth of Vigna mungo (L.) Hepper by preventing leaf senescence, was to be seen. It was found out that in Eucalyptus leaf extract in light, senescence was controlled in intact leaves. But in dark, senescence was promoted at concentrations, W/V - 1:200, but minimum senescence occurred at dilute concentrations and in control in intact leaves. In excised leaves, senescence was promoted at concentration, W/V - 1:200, both in light & dark. However, at other concentrations, darkness controlled senescence. Lower concentrations of Eucalyptus leaf extract are recommended as biofertilizers for Vigna mungo (L.) Hepper.

Phaseolus vulgaris is an important pulse, belonging to family Fabaceae, is an important source of vegetarian diet. Due to its food value, its plants are cultivated from very ancient times. For cultivation of plants, the first and foremost come roots, which help in fixation of plants and in supplying water and minerals to developing plants. Root studies from physiological point of view are very important. Here physiological aspect of root development has been studied in juvenile seedlings of Phaseolus vulgaris and rooting behaviour is studied in light and in dark. The root starts with emergence of radicle, an indication of germination of seeds. During further studies on root growth, the roots take over a particular length. The root length has been recorded here. Differentiation of lateral roots is again an important part of root architecture. Whether lateral roots initiate early or late has been observed here. Lastly average number of lateral roots differentiated at a particular point of time has been observed here. Here rooting behaviour of roots of Phaseolus vulgaris has been studied covering all above mentioned aspects in light and dark. Studies started with emergence of radicle at the time of seed germination and rooting behaviour of juvenile seedlings of Phaseolus vulgaris was observed for 7 days in light and dark. Light promoted emergence of radicle, while dark promoted rest of the root activities i.e. root length, differentiation of lateral and average number of lateral roots.

Large-scale quantitative analyses of associations between medicinal plants and health-related applications have been performed using, as examples, two databases: one specific for biomedical applications and the other more general-the world-wide web. Four plant species were selected for this analysis based on parameters such as common usage (e.g., Echinacea) and well-established therapeutic associations (e.g., Artemisia). Some common health-related parameters associated with these plants - e.g., malaria, infection, thrombosis, antioxidant activity- were also selected for analysis. The results with both databases were similar, and corresponded to the bestdocumented or most-researched medical roles for the plants or their bioactive phytochemicals. The analysis process is described along with calculations for determining optimal bioactivity association indices (AI). Interpretations of AI as well as influence of database type on such interpretations are discussed, e.g., influence of commercialization, and biochemical or clinical research. The analyses presented are generally applicable to medicinal plants and can also be used to analyze specific phytochemicals.

Med Pl 2010, 2(3), 219-23.

Ashwagandha (Withania somnifera L.) is considered as Indian Ginseng due to its great medicinal properties in its roots, leaves and fruits (berry). It is grown in India, Sri Lanka and Bangladesh. The production of its roots in India is about 1500 tonnes per year. A yellow mosaic disease on W. somnifera with a significant disease incidence was observed during the surveys in 2008-09 at Aligarh, Lucknow in Uttar Pradesh and Hindaun City in Rajasthan, India. The characteristic disease symptoms and whitefly population observed in the vicinity indicated the possibility of begomovirus infection. The association of a begomovirus was detected through electron microscopic observations and confirmed by positive amplification of expected size (<126>800 bp, 1.2 Kb) DNA fragments during PCR using two pairs of begomovirus specific primers. The begomovirus association with the disease of W. somnifera was concluded on the basis of virus transmission by whitefly, host range study, electron microscopic observations and positive amplification of expected size DNA bands by PCR using two pairs of begomovirus specific primers. The impact of begomovirus infection on growth and biomass yield W. somnifera plants was also studied which indicated significant losses to its biomass yield.

In Chhattisgarh state, powdery mildew disease appears on many hosts every year, in mild to sever form and causes considerable losses. Some times severe attack results in distortion of affected foliage leading to defoliation. Infection of flowering buds results in reduced fruit setting and poor yields. During survey work diseased leaves collected and packed in alcohol sterilized polythene bags and brought into the laboratory for microscopic examination. They have been described using characters of current taxonomic importance in defining the imperfect stages of Erysiphaceae in modern sense. In tropics they mostly occur in conidial states and named on host basis. But this criteria is of limited use since one species may infects several hosts. But the studies made by ^{1,2,3,4,5,6,7,8} have found several characters in imperfect state in combination which are important for diagnosis of these fungi. In view of this comparative study of the conidial states of powdery mildew fungi of Chhattisgarh have been made. Which revealed valuable information on morphology of conidial states of this region.

J basic appl Mycol 2009, 8(1-2), 14-8.

Different carbon or nitrogen sources tested three pathogenic isolates of B. theobromae showed little differences in growth. Galactose, maltose and sucrose showed luxuriant growth and poor growth on mannose and lactose. Fructose supported both growths as well as for sporulation. Among disaccharides tested sucrose was the best for the growth and sporulation. Among polysaccharide used as sources of carbon good growth was obtained on starch and cellulose but poor on pectin and carboxymethyl cellulose. Oligosaccharide maltose gave luxuriant growth with lactose gave poor growth. Among the inorganic nitrogen sources tested the fungus showed luxuriant growth on nitrates of potassium and sodium but poor on nitrite of ammonium. Ammonium oxalate and peptone also promoted good growth. All the three basic amino acids lysine, arginine and histidine supported good growth of B. theobromae. Both the sulphur-containing amino acids cystine and methionine promoted only little growth. Tyrosine supported excellent growth of all the three isolates of B. theobromae. All the three isolates of B. theobromae had the same preferences in utilizing the different carbon and nitrogen sources. As for growth regulators kinetine was a better source than IAA in promoting the fungal growth. The growth of the fungus was totally inhibited by 2, 4 D.

Int J Agric Envir Biotechnol 2009, 2(3), 294-8.

Squash seeds were treated with the powders of the pits of date palm (Phoenix dactylifera) and leaves of Lemongrass (Cymbopogon citrates) and tested against Rhizoctonia damping-off. The soil was artificially infested with Rhizoctonia solans. The treatment with the powder of waste parts of the two plants inhibited the mycelial growth of R, solani more than the biocontrol agent, Trichoderma harziarium. The inoculation of soil with the biocontrol agent Jrichoderma harzianum controled the damping-off disease in the artificially infested soil and the combination between seed treatments with waste plant powders and soil treatment with T. harzianum improved the efficacy of the biocontrol agent.

J appl Zool Res 2009, 20(1), 61-71.

Extracts of 18 plants viz., Gymriema sylvestre, Ficus glomerate, Grewia subinaequalis, Pterocarpus marsupium, Juniperus communis, Tinospora cordifolia, Balsamodendron mukul, Trigonella foenum-graecum, Convolvulus pluhcaulis, Phyllanthus niruri, Mucuna pruriens, Cichorium intybus, Emblica officinalis, Syzygium cuminii, Momordica charantia, Terminalia bellirica, Terminalia chebula and Sphaeranthus indicus tested, only 13 plants showed significant results and dropped each observed level as compared to diabetic control group, which was almost equivalent to the levels of normal group. Five extracts viz., T. cordifolia, E. officinalis, S. cuminii, T. bellirica and T. chebula did not exert any favourable change while two extracts Grewia subinaequalis and Convolvulus pluricaulis were at par to normal in 8th week and invariably led to the formation of complications like diabetic retinopathy, swelling of feet and damage to skin of tail and legs. Two extracts G. sylvestre and S. indicus were significantly effective within 14 days after alloxan administration, and the values were almost similar to normal. In treated diabetic group the chronological order of the remaining nine plant extracts in dropping the observed levels with their respective time period was J. communis in four weeks, F. glomerata, P. marsupium, B. mukul, T. foenum-graecum, P. niruri, M. pruriens, C. intybus and M. charantia in six weeks. Further pharmacological and biochemical investigations are under way to elucidate the mechanism of anti-diabetic activity of eleven plant extracts.

A phyto sociological survey was conducted in wastelands of Kolhapur district at six different localities viz Kolhapur, Jotiba, Warange, Kagal, Radhanagari and Bambawade. The survey revealed that at all six localities, 35 weed species were found associated with weedy Cassia (C. obtusifolia, C. tora & C. uniflora). At Kolhapur, maximum (15) species were associated, while at Jotiba, Warange, Kagal, Radhanagari and Bambawade, 14, 10, 12, 10 and 11 species were found associated respectively. Among these, Alternanthera, Achyranthes, Sida, Synedrella, Setaria and Brachiaria species were common. However, degrees of their association were different at different localities. The data of distribution pattern at all studied localities revealed that C. obtusifolia, C. tora, C. uniflora, Setaria, Brachiaria, Hyptis and Alternanthera recorded the high Important Value Index (IVI) compared to other species. C. obtusifolia had the higher IVI than that for other Cassia species except at one locality i.e. at VI (Bambawade) where C. tora exhibited higher IVI. The higher value of IVI indicates dominant nature and allelopathic influence of Cassia species on neighbouring plants.

Fungi are distributed as parasites, saprophytes or symbionts in all types of ecosystems across the world. So far, nearly 1,00,000 species have been explored and given scientific names¹ while estimated number on the earth is 7-9.5 millions species². Molecular characters based on the DNA bar coding cannot always distinguish between closely related species of plants or fungi³. New criterion will be needed for proper identification of this huge number of fungal species. Hence, seven formulae have been formulated for numerical identification (taximetrics) of fungi to supplement morphological, biochemical and molecular criteria.

The cyanobacterium, Nostoc muscorum, was examined for the caesium toxicity in the diazotrophic growth medium in the presence/absence of Na⁺/K⁺. CsCl at a concentration of 2mM was found lethal to the diazotrophically grown cultures. Addition of graded concentration of Na⁺ and K⁺ mitigates Cs⁺ toxicity. The Cs⁺ toxicity is less when the culture medium supplied with both Na⁺ and K⁺, simultaneously. The effect of pH was studied to determine Cs⁺ toxicity at higher alkaline pH. The examined cyanobacterium showed more sensitivity towards Cs⁺ when exposed to higher alkaline pH. Hence, it is concluded that Cs⁺ accumulation and toxicity are closely related to cellular Na⁺ and K⁺ status and external pH. The information regarding interaction between Cs⁺ and other monovalent cations can be helpful in removing and recovering Cs⁺ from the Cs⁺-polluted habitats.

Eight plant extracts significantly reduced the weight of ovary as compared to control are in chronological order of A precatorius, J. arborescens, C. deodar, P. harmala, O. tenuiflorum, A. hexapetalus, M. oleifera and M. philippensis, while the two plant extracts viz M. tuberosa and A. detchoma are at par to the control in all the four objects of the evaluation. The same effective eight plant extracts also acknowledged to reduce the weight of uterus although their merit order was slightly changed due to abrupt estrous cycle and could be placed as A. hexapetalus, M. oleifera, A. precatorius, C. deodar, 0. tenuiflorum, P. harmala, J. arborescens and M. philippensis. The increase in ascorbic acid as well as cholesterol was quite significant in treatments with eight plant extracts, the laparatomized females showed the normal internal morphology, except in the case of A. detchoma were the liver was absolutely inactive and pale yellow therefore, it was not at all clinically fit for the anti-fertility activity. Significant reduction in the synthesis of ovarian steroid reduced the weight of ovary and uterus. The six plant extracts viz., A. hexapetalus, M. oleifera, A. precatorius, C. Deodar, P. harmala and J. arborescens caused maximum reduction in ovarian steroidiigfenesis and established themselves to have high potentiality to reduce fertility in transient phase without any harm to vital activities of the body. Elevated level of cholesterol and ascorbic acid content caused hypo functioning of the ovary.
