Effectiveness of Herbicide to Control Rice Weeds in Diverse Saline Environments

Integration of Allelopathy to Control Weeds in Rice

Rice (Oryza sative L.) is the main food crop in Asia and the staple food of the majority of the population in many regions of the world. The population pressure in rice-consuming countries demands that more attention be directed towards new approaches to sustainable rice produc‐ tion. Improvement of both crop quality and yield is an urgent task [1]. Optimally, rice yield improvement must be sou...

IN VITRO TECHNIQUES COUPLED WITH IRRADIATION FOR SELECTION OF BASMATI RICE MUTANTS BE'ITER ADAPTED TO SALINE ENVIRONMENTS

Among different doses of gamma rays, 1.5 kR induced 71.84% callus in Basrnati rice in amodified MS medium and 2% redifferentiation under anon-saline environment, 20% callusing response with 7.5%,2.8% and 2.5% redifferentiation was induced by 2.0 kR at electrical conductivity (EC) of 4,s and 6 dS.m of NaCl respectively, in regeneration medium. A non-irradiated non-saline environment reveale...

Herbicide Metabolism in Weeds — Selectivity and Herbicide Resistance

The metabolic detoxication/bioactivation pathways, the levels and activity of enzymes, and endogenous cofactors mediating these reactions in crops have been well document‐ ed; however, much less evidence has been accumulated in weed species. The herbicide metabolism as a selectivity factor is summarized with special attention to acetyl-CoA car‐ boxylases (ACCase)-inhibiting aryloxyphenoxypropio...

Herbicide Resistant Weeds and Crops

Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
