- Journal of Plant Growth Regulation
- 1 June 2013
The aim of this work was to investigate the balance between the activities of ascorbate peroxidase (APX) and phenol peroxidases (POD) and cowpea root growth in response to dehydration and salt… Expand
Changes in physiological indicators associated with salt tolerance in two contrasting cashew rootstocks
L.) rootstocks in response to salt stress. The tolerant CCP 09 genotype showed better growthperformance after two weeks under a large range of NaCl salinity (50, 100, 150 and 200 mM). The NaCl… Expand
Salt-induced changes in antioxidative enzyme activities in root tissues do not account for the differential salt tolerance of two cowpea cultivars
The salt stress effect in root growth and antioxidative response were investigated in two cowpea cultivars which differ in salt tolerance in terms of plant growth and leaf oxidative response.… Expand
