تأثیر عوامل اکولوژیکی بر ساختار تشریحی برگ و دمبرگ انگور وحشی در شمال ایران
Wild grapevine, Vitis vinifera subsp. sylvestris is considered as a rare species in Europe and Iran and possesses restricted distribution due to threatening factors. Natural populations of wild grapevine in the north of Iran were evaluated in three wild areas of coastal and plains areas of Miankaleh, submontane areas of Amol and the forest patches of Kojour and a cultivated sample of crop grape...
متن کاملComparison of Foliar and Soil Fe Fertilization on Medicago scutellata Physiological-Biochemical Characteristics and Active Iron in Soils Containing Different Amounts of Lime
Reducing iron solubility in calcareous soils causes iron chlorosis symptoms in the plant. In order to investigate the response of M. scutellata to direct and indirect iron deficiency, a factorial experiment was conducted in a completely randomized design with three replications. The experimental factors included three levels of lime (0, 4 and 8%) and five levels of Fe (0, 5 and 10 mg Fe Kg soil...
متن کاملارزیابی تحمل به تنش خشکی در جو زراعی و وحشی براساس صفات فیزیولوژیک و شاخص‌های تحمل
Drought stress is one the most limiting factors for crop production worldwide. The wide ecological and environmental dispersion of crop wild relatives, generates a high potential of their adaptive diversity to abiotic stresses such as drought. In this study 21 (including 10 cultivated and 11 wild barley (Hordeumvulgaressp. spontaneum))genotypes were evaluated under three soil water conditions f...
متن کاملThe Impact of Lime and Gypsum on Sugarcane Yields and Soil Acidity in the South African Sugar Industry
The yield responses of sugarcane to lime and gypsum at two sites in the KwaZulu-Natal Midlands of South Africa are presented and discussed. At Dalton, on a Magwa form soil with an initial aluminium saturation index (ASI) of >80%, over a plant and four ratoon crops variety N12 gave no significant response to dolomitic lime. By contrast, variety N16 gave consistent yield responses to lime at rate...
متن کاملPhysiological and morphological responses of rice (Oryza sativa L.) to varying water stress management strategies
Sustainability of rice production under limited water conditions is threatened by increasing irrigation water scarcity. Therefore, physiological and morphological responses of rice to varying water stress management strategies should be determined. The physiological and morphological responses of a semi dwarf rice (Hashemi cultivar) to water stress intensities (mild and severe, i.e., short-dura...
