چکیده

Salinity stress severely affects the growth, physiological and developmental processes in plant species. Melia dubia is an ecologically economically important tree species of Indian subcontinent. However, systematic information with respect to salt tolerance potential completely lacking. Under conditions, determining suitable soil EC range required for better survival, growth productivity In present study, we investigated effects different salinity (EC 4, 8, 12) levels on ion homeostasis, physio-biochemistry, morphology, M. plant. Results revealed that increase causes higher Na+ content Na+/K+ ratio, while lower K+ content, leaf tissues dubia. The such as photosynthetic rate, stomatal conductance, internal CO2 concentration, transpiration rate were adversely affected increased levels. Morphological parameters, internodal length, petiole width also decreased (P<0.05) under saline conditions. further indicated significantly was found optimum upto 8 EC, thereafter it slightly 12 EC. Our findings showed significant changes physiological, morphological, pattern Therefore, based experiment, soils at moderate (20–25%) reduction.

Effects of Exogenous Nitric Oxide on Germination and Physiological Properties of Basil under Salinity Stress

Nitric oxide (NO) is a bioactive molecule, which was found to have several physiological roles, including antioxidant. To have a better understanding of the effects of NO concentrations (0, 0.1 and 0.2 mM) on germination, growth, photosynthetic pigments, lipid peroxidation and antioxidant activity of basil (Ocimum basilicum L.) under different salinity concentrations (0, 100 and 200 mM of NaCl)...

Investigating the effect of copper nanoparticles on morphological, physiological, biochemical properties and yield of Mallow under drought stress conditions

To evaluate the effect of copper nanoparticles on the characteristics of mallow under drought stress conditions, a factorial experiment was conducted in a completely randomized design with three replications under greenhouse conditions in 2017. The first factor of drought stress was at three levels without stress and 75 and 50% of field capacity and the second factor was copper nanoparticles at...

Physiological responses of peppermint (Mentha piperita L.) to plant growth regulators and salinity stress

Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...
