“…Similar decrease in chlorophyll content also observed by Baisak et al (1994), Alam et al (2013) and Pandey et al (2014) under drought stress. On recovery, chlorophyll content increased in all varieties of blackgram but was less than that of respective control plants.…”

“…In India it is the third important pulse crop (Arulbalachandran et al, 2010). However, production of blackgram is adversely affected by various environmental stress factors, especially drought that reduce yield (Souframanien and Gopalakrishna, 2006;Kundu et al, 2011;Pandey et al, 2014). Various strategies as drought escape, drought avoidance and drought tolerance are used by plants to complete their life cycle under stress.…”

“…Least increase in total phenolics was observed in RBU38 plants while T9 and VM4 plants showed almost same pattern under short-term drought stress as well as on recovery. Phenolic compounds provide protection to plants to biotic and abiotic stress (Chakraborty et al, 2008;Mandal et al, 2010;Jha et al, 2013;Pandey et al, 2014). Bars are mean ± SD; bars followed by same alphabets are not significantly different at p≤0.05 according to ANOVA and DMRT.…”

Plants apply several strategies that are developed during their evolution and artificial domestication to overcome biotic and abiotic stresses. Among eminent environmental threats drought stress is a major factor that affects plants at physiological, biochemical and molecular level. Blackgram (Vigna mungo) is an important pulse crop but its productivity is adversely affected by drought. In the present work, different cultivars of blackgram i.e. T9, RBU38 and VM4 are taken to find out the effects of drought stress by the estimation of different biochemical parameters to better understand biochemical pathway modulations under stress and its possible mitigation. Damage to photosynthetic machinery as evident by decrease in chlorophyll content and loss of membrane integrity in the plants under drought stress. The adverse effects of drought on the plants were averted to a certain extent in RBU38 by activation of defence signalling through H2O2 at lower concentration, which proved damaging at high concentration for T9 and VM4 and a concurrent increase in proline content which may provide protection against oxidative stress. This study suggests that drought modulated biochemical parameters can be used as reliable indices for selection of genotypes with a better stress tolerance.

“…Biotic and abiotic stresses have ability to suppress the growth and adversely affects the productivity of the leguminous plants. Symbiotic interaction between legume plant roots and microorganisms enhance the defence mechanism against these stresses and cross inoculation of selected strains can be used for this purpose (14)(15)(16). In the present study, a bacterial isolate was characterised from the root nodules of Arachis hypogaea cv.…”

Groundnut, a major pulse crop, is prone to fungal diseases especially collar rot at seed germination and early seedling stage. In the present study, symbiotic bacteria was isolated and characterised from a collar rot resistant groundnut variety, Mallika and identified as Rhizobium pongamiae following biochemical and molecular characterization (NCBI Acc. No. MK770416). The bacterial isolate on cross inoculation, may be useful in improving crop productivity and enhancing collar rot disease tolerance in susceptible crops.

“…Vigna mungo (L.) Hepper, commonly known as black matpe or blackgram, contributes 20% to overall world pulse production and in India it is the third important pulse crop (Arulbalachandran et al, 2010). However, production of black matpe is adversely affected by various environmental stress factors, especially drought that reduce yield (Pandey et al, 2014).…”

Growth, physiological and biochemical activities of black matpe bean grown in pot cultures were evaluated to recognize the ameliorative role of potassium against the deleterious effects of water deficit. Black matpe plants were subjected to four levels of water stress (400 ml, 200 ml, 100 ml and 50 ml). The control plants were supplied with 500 ml of water at regular intervals. Potassium was applied in form of 200 ppm KCl and KNO 3 . Plants were under observation starting from 25 upto 55 days of plant growth at 10-day interval for each treatment. Water deficit stress reduced biomass, leaf area and RWC and provoked oxidative stress in plants as confirmed by considerable increase in electrolyte leakage, proline and reducing sugar content. Foliar application of KCl and KNO 3 improved all these attributes under water stress. The ameliorative effect might be maintained through decrease in proline and increase in reducing sugar content. Increased reducing sugar content in K treated plants may have a significant role in osmotic adjustment.
