Optimum Time of Last Irrigation for Cotton Cultivars FH-634 and CIM-443

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

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...

Environmental interaction, additive and non-additive genetic variability is involved in the expression of tissue and whole-plant heat tolerance in upland cotton (Gossypium hirsutum. L)

Heat tolerance is measured at tissue level by cellular membrane thermostability (CMT) and at the whole plant level by the heat tolerance index (HTI). Eight upland cotton cultivars and 15 crosses were used to determine the type and extent of genetic variability associated with the expression of these traits between and within environments. Heat stress and non-stress conditions were used as the C...

Evaluation of six cotton cultivars for their resistance to thrips and leafhoppers

Arthur Cotton and Irrigation in Tasmania

BLACKBURN, G., 1985 (31:vii): Arthur Cotton and irrigation in Tasmania 1839-43. Pap.Proc. R.Soc. Tasm. 119:1-5. ISSN 0080-4703, 78 Allinga Ave, GJenunga, South Australia, 5064. Cotton, an officer of the East India Company with experience of irrigation, visited Tasmania for periods totalling three years. His influence was important in gaining acceptance of irrigation as an aid to cereal producti...

Pollen Germination of Diverse Cotton Cultivars

High temperatures during cotton flowering and early boll development can detrimentally affect cotton yield. Current commercial cultivars do not have pronounced tolerance to elevated temperatures, and improved methods of screening for thermo-tolerance are needed. The effect of heat stress on cotton has been measured with several different methods including membrane leakage, chlorophyll fluoresce...
