Nutrient status on the leaf alters as it matures, which often restructures the microbial population. To understand the effect of age on phylloplane colonization, two varieties of tomato (Pusa early dwarf and F1-Priya-6636) were sampled. Various stages of leaf development and microbial colonization was studied by leaf imprint culture method. The bacterial species were identified by 16S rRNA sequencing, and fungal species by microscopic methods. The dominant bacterial species were Pseudomonas koreensis, P. stutzeri, P. jesseni, Sphingobacterium daejonense, Klebsiella pneumoneae, Serratia fonticola and fungal species were Alternaria alternata, A. citrifolia, Aspergillus niger, A. flavus, A. candidus, A. nidulans, Penicillium expansum, Curvlaria lunata, Cladosporium cladosporioides, C. herbarum, Fusarium oxysporum, Trichoderma harzianum and Rhizoctonia solani. Leaf surfaces were investigated by assessment of microbial colonization patterns. Adaxial surface was found to be densely populated with age.

Wheat (Triticum aestivum L.) is the chief crop consumed for the source of energy, and is a staple food for ever growing population. Its yield must be increased sustainably for food security; but weeds are one of the deterrents in its yield production. Among the different herbicides used for control of weeds in wheat, isoproturon, a phenyl urea herbicide, is most commonly used due to its cost-effective nature and broad spectrum control ability of weeds. But the extensive use of the herbicides leads to deterioration of plant ultimately adversely affecting crop yield. Therefore, the present study was undertaken to observe the response of wheat cultivars to isoproturon application to know their potential to protect the photosynthetic and growth capability against isoproturon. Five cultivars of T. aestivum (HD-2851, PBW-550, PBW-343, PBW-502 and DBW-16) were screened against varying concentration of isoproturon application (0, 2, 5, 10 and 20 ppm) to select tolerant and sensitive cultivars in terms of photosynthetic and growth characteristics. The application of 20 ppm isoproturon most severely damaged photosynthesis and growth of the tested cultivars, while the other doses were less harmful. The cultivar PBW-343 showed maximum tolerance while cultivar PBW-502 was the most sensitive for the given isoproturon doses. The cultivar PBW-343 may be used safely for wheat cultivation even in the presence of isoproturon herbicide.

Glycyrrhiza glabra L. belonging to the family Leguminosae is an important medicinal plant. The medicine is obtained from roots which require uprooting of the whole plant. The present study describes an efficient reproducible protocol for the regeneration of whole plantlets and successful acclimatisation in soil conditions. The nodal explants were cultured on Murashige and Skoog (MS) medium augmented with different cytokinins; 6-(3-Hydroxybenzylamino) purine (BA), 6-Furfurylaminopurine (Kn) and meta-Topolin (mT) for the induction of adventitious shoots. The best results were obtained in a combination treatment of 2.5 μM mT and 5.0 μM BA producing a maximum of 8.03 ± 0.11 shoots. Subculture onto the optimum medium composition further enhanced the shoot formation. Augmentation of 2.5 μM Indole3-butyric acid (IBA) in MS medium proved to be optimal for the production of a maximum of 6.80 ± 0.37 roots/shoot. The plantlets were acclimatised successfully in soilrite with 90% success and exhibited normal morphology and growth when compared with the parent plant.

A pot experiment was conducted in the net house of environmental plant physiology laboratory, department of Botany, Aligarh Muslim University, to study the comparative effect of sewage wastewater and ground water on the performance of linseed (Linum usitattisimum L.) cv Neelam. Sewage wastewater proved more efficient in enhancing growth, leaf NPK content, chlorophyll content, yield and oil content. However, iodine value was lower in plants receiving sewage wastewater which is considered good as far as varnish industry is considered. The physico-chemical characteristics of sewage wastewater were within the permissible limits of Bureau of Indian standards.

Phytoextraction, the use of hyperaccumulator plant species to scavenge toxic heavy metals from contaminated soils are considered as an emerging technique for cost effective and environmental friendly detoxification. The present study was conducted to evaluate the scavenging efficiency of in-vivo gown Musa paradisiacal L. for the uptake of Cd, Pb, Cr and Ni. Excessive heavy metal accumulation can be toxic to most plants leading to reduction in seed germination, root elongation and biomass production; inhibition of chlorophyll biosynthesis as well as disturbance in cellular metabolism and chromosome distortion. For studying the heavy metals load of sewage sludge and their effect on crop quality in relation to non applied sites, solid sludge and fruit plant Musa paradisiacal L. was collected from seven Sewage Treatment Plants viz. Howrah, Garulia, Bhatpara, Nabadwip, Srirampur, Kona, Chandannager and from the Periurban areas viz. Nadia/Chakdaha/Ektapur(N/C/E), Nadia/Chakdaha/Pumlia, Nadia/Chakdaha/Sikarpur(N/C/S), Nadia/Chakdaha/Tatla (N/C/T). The results suggest that fruit plant like Musa paradisiacal L. has more scavenging capacity for Pb and Cd and if this plant is cultivated in sites abundant with above heavy metals, this would scavenge the heavy metal toxicity from the soil.

Among various environmental stresses, soil salinity is one of the most severe stress factors that may impair crop productivity. Increased salinization of arable land is expected to have devastating global effects resulting 50% land loss by the year 2050. The physiological and biochemical responses of two different mustard cultivars (cv. Varuna and cv. SS2) to salt stress were studied under green house conditions. The plants were grown in pots and were treated for 7 days with NaCl starting at the appearance of the first trifoliate leaf unfolded. It was established that the applied dose of NaCl caused stress in the young mustard plants, which found expression in the suppression of growth and photosynthesis activity. The applied NaCl caused stronger inhibition in both the cultivars but the effect was more pronounced on cv. SS2 than cv. Varuna. The amount of carbohydrate in the tissues of the salt-treated plants increased, while the cell water potential was reduced. Adaptation of plants to salinity is associated with osmoregulation adjustment. Variation in carbohydrate accumulation is of particular importance because of their direct relationship with physiological processes as photosynthesis, translocation and respiration. Further, accumulation of carbohydrate under salinity stress is an osmotic adjustment that helps plants to survive under stress and greater accumulation in Varuna and least in SS2 helps in categorizing Varuna as a tolerant cultivar.
