Is Soil Temperature Better than Air Temperature for Predicting Winter Wheat Phenology?
In predicting wheat (Triticum aestivum L.) phenology, logic suggests that basing thermal unit accumulation on near-surface soil temperature should give a better representation of shoot apex thermal unit accumulation than air temperature until internode elongation raises the apex above the soil surface. A study was undertaken to determine if predictions of winter wheat phenology are improved whe...
متن کاملRelationships among vernalization, shoot apex development and frost tolerance in wheat.
BACKGROUND AND AIMS Frost tolerance of wheat depends primarily upon a strong vernalization requirement, delaying the transition to the reproductive phase. The aim of the present study was to learn how saturation of the vernalization requirement and apical development stage are related to frost tolerance in wheat. METHODS 'Mironovskaya 808', a winter variety with a long vernalization requireme...
متن کاملInteractive Effects of Vernalization, Photoperiod and Light Intensity on Reproductive Development of Wheat Cultivars
475 Abstract: The interactive effects of vernalization, photoperiod and light intensity on the length of the apex or spike and main shoot, and the diameter of the main shoot of five different wheat (Triticum aestivum L.) cultivars (Çukurova-86, Atay-85, Lancer, Haymana79 and Bezostaya-1) having different biological characters were investigated. The research was carried out in four independent e...
متن کاملMetabolic and Ultrastructural Changes in Winter Wheat during Ice Encasement Under Field Conditions.
The effect of ice encasement on the physiological, metabolic, and ultrastructural properties of winter wheat (Triticum aestivum L.) grown under field conditions was examined by artificially encasing winter wheat in ice during early winter. Cold hardiness and survival of ice-encased seedlings declined less rapidly in Kharkov, a cold-hardy cultivar than in Fredrick, a less hardy cultivar. Ethanol...
