Parameters of Winter Wheat Growing and Development after Mutagen Action
Dry seeds of seven winter wheat varieties and one line were exposed by gamma-rays and chemical mutagens to determine their effect on plant grows and development. Next parameters have been investigated – plant survival, pollen fertility, components of yield structure. Informative value by mutation depression evaluation of all parameters has been developed. The most informative parameters for mut...
متن کاملGenetic Architecture of Anther Extrusion in Spring and Winter Wheat
Hybrid wheat breeding is gaining prominence worldwide because it ensures higher and more static yield than conventionally bred varieties. The cleistogamous floral architecture of wheat (Triticum aestivum L.) impedes anthers inside the floret, making it largely an inbreeder. For hybrid seed production, high anther extrusion is needed to promote cross pollination and to ensure a high level of pol...
متن کاملWater Stress Effects on Winter and Spring Leaves Anatomy of Different Wheat (Triticumaestivum L.) Genotypes
Water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of SB University of Kerman using five wheat cultivars.Xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. Results showed that significant difference exists...
متن کاملRelationship of base temperature to development of winter wheat
Development of wheat (Triticum spp.) is primary driven by temperature, but is also affected by other factors such as vernalization and photoperiod. Crop growth and development are often described in terms of calendar days. However, determining the development in terms of thermal time or physiological time is more accurate because it is an accumulation of the caloric energy needed for the o...
متن کاملCan Growing Degree Days and Photoperiod Predict Spring Wheat Phenology?
Wheat (Triticum aestivum) production in the rainfed area of Pothwar Pakistan is extremely vulnerable to high temperature. The expected increase in temperature due to global warming should result in shorter crop life cycles, and thus lower biomass and grain yield. Two major factors control wheat phenological development: temperature and photoperiod. To evaluate wheat development in response to t...
