Daily intake of Cd through food is posing serious health problems. There is an urgent need to reduce the uptake and accumulation of Cd in wheat and other cereal crops. In this study, we investigated the potential of moringa leaf extract (MLE) in decreasing the Cd toxic effects in wheat (Triticum aestivum L.) cv. A.S. 2002. Sowing was carried out in pots under shade and natural light conditions. Two Cd concentrations (500 µM and 1000 µM) were applied with and without MLE (0 and 3%). Results revealed that plant growth parameters viz diameter of stem, number of leaves, leaf area, photosynthetic pigments were improved with MLE application under Cd stress. Moreover, biochemical attributes and osmolytes such as total soluble sugars, and soluble proteins, phenolic content and flavonoids were negatively effected by Cd stress and were improved under MLE treatment. Moreover, Cd stress enhanced phytotoxicity as higher RO...

The experiment was laid out following a randomized complete block design with three replications. Observations were recorded on quantitative traits i.e. plant height, leaf area, head diameter, 100 achene weight, achene weight per plant, stem girth, internodal distance and descriptive traits (Leaf shape, head angle, achene colour, achene stripes and seed sizes). The data were subjected to analysis of variance, correlation and path coefficient analysis to evaluate the genetic variability in the breeding material and to estimate association among various traits. Correlation analyses indicated that seed weight per plant and 100 seed weight was found to be positively correlated with all the traits studied except for internodal distance. Direct and indirect effects of various quantitative traits on achene yield per plant was observed. Plant height, leaf area, head diameter and internodal distance had direc...

Considerable increase in concentration of lead in upper layer of cultivated soil has been observed in vicinity of industrial and urban areas (De Abreu et al., 1998). Regulatory measures have been adopted in various countries to check input of lead in environment, but it is still most important environmental issue in underdeveloped countries. Extensive use of agricultural chemicals (fertilizers, pesticides, herbicides), combustion of leaded gasoline, emission from nonferrous metals and input of industrial and municipal waste causes addition of lead (Pb) to agricultural soils (Davies, 1990). Unfortunately, no major breeding program was organized in the past to minimize losses caused by lead stress. Breeders have to define targets, evaluate natural variability for lead tolerance, select appropriate breeding methods, develop selection criteria on the basis of traits rela...
