in this study the effect of salt stress on banding patterns of superoxide dismutase (sod), catalase (cat) and peroxidase (pox) in 18 genotypes of white common bean (phaseolus vulgaris l.) were examined under two levels of nacl )0 and 400 mm) stress. for each isozymic band the “density × area” scores on gels were evaluated by mcid software and considered as enzymatic activity. three isozymes wer...

Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...

this study was conducted on two canola (brassica napus) cultivars, okapi a winter type and cold tolerant and rgs003 a spring type and cold sensitive. seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °c (day/night, control). at the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°c (day/night, cold treatment) an...

The effect of different thiourea (TU) concentrations (10 and 20 mM) on antioxidants, protease activity and protein content with and without H2O2 (50 mM) induced stress was investigated in wheat leaves. A gradual decrease in protein content with a peak at 72 hours was observed in stressed as well as control leaves. This gradual decrease in leaf protein content at different time intervals was com...

This paper aims to present a review of seed technology, seed germination and vigor methods using image processing. Computer–aided image analysis techniques have been recently developed in monitoring seed growth and vigor. Their integration with the standard germination test is needed to describe the germination performance of a seed sample with high accuracy. The use of various modern image acq...

Although copper (Cu) is an essential micronutrient for plants, a slight excess of Cu in soil can be harmful to plants. Unfortunately, Cu contamination is a growing problem all over the world due to human activities, and poses a soil stress to plant development. As one of the most important biological processes, seed germination is sensitive to Cu stress. However, little is known about the mecha...

Green cumin is an herbaceous, annual, delicate, and aromatic plant in the family Apiaceae, also known with other names such as " kammun " and "senut", which is among the oldest and most economical as well as the second most popular medicinal plants after black pepper. In this study, pretreatment of cumin seed was studied with plasma technology without using chemicals through damage to seed for ...
