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...
متن کاملNanoparticles Based on Chitosan as Carriers for the Combined Herbicides Imazapic and Imazapyr.
The use of lower concentrations and fewer applications of herbicides is one of the prime objectives of the sustainable agriculture as it decreases the toxicity to non-targeted organisms and the risk of wider environmental contamination. In the present work, nanoparticles were developed for encapsulation of the herbicides imazapic and imazapyr. Alginate/chitosan and chitosan/tripolyphosphate nan...
متن کاملDifferential oxidative metabolism and 5-ketoclomazone accumulation are involved in Echinochloa phyllopogon resistance to clomazone.
Echinochloa phyllopogon (late watergrass) is a major weed of California rice (Oryza sativa) that has evolved cytochrome P450-mediated metabolic resistance to different herbicides with multiple modes of action. E. phyllopogon populations from Sacramento Valley rice fields have also recently shown resistance to the herbicide clomazone. Clomazone is a proherbicide that must be metabolized to 5-ket...
متن کاملIdentification and Mechanism of Echinochloa crus-galli Resistance to Fenoxaprop-p-ethyl with respect to Physiological and Anatomical Differences
Identification and mechanism of Echinochloa crus-galli (L.) resistance to fenoxaprop-p-ethyl via physiological and anatomical differences between susceptible and resistant were investigated. The physiological and anatomical differences that were take into account were growth reduction, chlorophyll content reduction, lamina thickness, and xylem vessel diameter in both susceptible and resistant b...
متن کاملمطالعه واکنش علف‌‌هرز سوروف (Echinochloa crusgalli) و سوروف برنج (Echinochloa oryzoides) به ارتفاع آب و عمق خاک
به منظور مطالعه تأثیر ارتفاع آب و عمق خاک بر سوروف و سوروف برنج، آزمایشی گلدانی در مؤسسه برنج کشور (رشت) در بهار سال 1387 انجام شد. تیمارها شامل گونه علف‌‌هرز (سوروف و سوروف برنج)، ارتفاع آب (0، 3، 6 و 9 سانتی‌متر) و عمق قرارگیری بذر در داخل خاک (5/0، 5/1، 5/2 و 5/3 سانتی‌متر) بودند. آزمایش به صورت فاکتوریل در قالب طرح بلوک‌های کامل تصادفی با چهار تکرار اجرا گردید. نتایج تجزیه واریانس نشان داد ...
