Post-anthesis Drought Stress Effects on Photosynthesis Rate and Chlorophyll Content of Wheat Genotypes
Water stress is one of the major abiotic stresses in agriculture worldwide. In order to assess photosynthesis response and grain yield of 25 wheat genotypes under water deficit (post-anthesis stress) conditions, a 2-year study (2010-12) was carried out as a split-plot arrangement using randomized complete block design with three replications. The most sensitive gas exchange variable to water de...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
effect of drought stress and some microelements on fluorescence chlorophyll parameters, chlorophyll content, rwc, ec, and grain yield in corn (sc704)
an investigation of chlorophyll quick fluorsence variations was made in the reaserch field of islamic azad university- karaj in 2007. the experimental design was a split plot one in form of a complete randomized block design with 4 replications. drought stress was cosiderded in three levels of 40%, 60%, and 75%, on the basis of depletion of soil moisture as the main factor and the factor of mic...
متن کاملQtl Mapping of Wheat Doubled Haploids for Chlorophyll Content and Chlorophyll Fluorescence Kinetics under Drought Stress Imposed at Anthesis Stage
Drought stress is one of the major environmental constraints to crop plants including wheat worldwide. Synthetic hexaploid can act as a vehicle for improving crop tolerance against biotic and abiotic stresses. Doubled haploid population consisting of one hundred and forty individuals derived from cross of Opata and SH223 was used in the present study to identify genomic regions associated with ...
متن کاملeffects of methanol application on sugar beet (beta vulgaris) relative water content, chlorophyll content and chlorophyll fluorescence parameters under drought stress conditions
to evaluate the effects of methanol and drought stress on chlorophyll fluorescence parameters, chlorophyll and relative water content in sugar beet, a study was conducted in 2008 in maahdasht (karaj, iran). aqueous solutions of 0 (control), 7, 14, 21, 28, 35% (v/v) methanol with each solution containing 0.2% glycine and a second factor, namely drought stress (irrigation after 70% depletion of a...
