Difference in efficacy among flowable, wettable powder and granule formulations of several herbicides against Echinochloa oryzicola.

Photoactivation of Chlorophyll Synthesis and Cytochrome Oxidase Activity in Anaerobically Germinated Seedlings of Echinochloa crusgalli var. Oryzicola.

When seeds of Echinochloa crusgalli var. oryzicola are germinated in dark anaerobic conditions (99.995% N(2)), the seedlings do not have detectable protochlorophyll(ide). Two hours after exposure to light aerobic conditions, they begin to synthesize chlorophyll. The lag in greening is shorter in seedlings exposed to light for 24 hours before exposure to air. Seedlings maintained in light anaero...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

an investigation into elt teachers’ sense of self-efficacy in teaching reading comprehension and their personality types

as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...

Beta-Alanine Protection of Yeast Growth Against the Inhibitory Action of Several Chlorinated Aliphatic Acid Herbicides.

Chloro-substituted acetic, propionic, and isobutvric acids constitute a class of compounds which in recent ytears hav-e demonstrated considerable potential use for the control of a number of weedy grasses in several weed-crop situations. The structural similarityr of these compounds to propionic and acetic acids makes it seem probable that their phvtotoxicity might re-sult, in part, from interf...
