Effects of post-anthesis heat stress and nitrogen levels on grain yield in wheat (T. durum and T. aestivum) genotypes
In order to study the effects of post-anthesis heat stress and nitrogen levels on grain yield and yield components of wheat genotypes, two separate field experiments were conducted in delayed and optimum sowing dates under Ahvaz conditions (2006-2007). The Ahvaz site located in south west of Iran (32°20' N, 40°20' E) with subtropical climate condition. The experiment site had a moderate w...
متن کاملEffect of Salinity Stress on Grain Yield and Grain Quality in Wheat (Triticum aestivum L.) Lines
The effects of salinity stress on grain quality traits of wheat were investigated using 180 lines of F5 generation in two environments (normal and salinity stress). A randomized complete block designs with three replications was used in each of the environments at the Research Farm of the Agricultural and Natural Resources Research Station of Isfahan in 2019-2020 cropping season. Grain yield, p...

متن کاملPhotosynthesis, grain yield, and nitrogen utilization in rice and wheat.
Rice (Oryza sativa) and wheat (Triticum aestivum) are the two most commercially important crops, accounting for more than 40% of global food production. They were domesticated in different climates and differ largely in their growth environments: Rice is tropically cultivated in hot, wet climates, whereas wheat tends to be grown in cooler temperate climates. However, both crops have been bred i...
متن کاملPost-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...
