Abstract

The effects of seed rate on seed growth rate of wheat varieties, a factorial experiment in a randomized complete block design with three varieties of wheat (Koohdasht, Chamran and Zagros) and seed rate (35, 70, 105, 140 and 175 kg per hectare) were conducted at the agricultural Research Station in Khorramabad. Components for grain growth after pollination eight sampling intervals of five days, grain dry weight was measured. The results showed that grain yield, biological yield, straw yield and number of ears per square meter and highly significant positive correlation, negative correlation with seed weight and hectoliter weight but very significant and the number of grains per spike, and for high-speed grain non-significant negative correlation. All three varieties of the grain dry weight showed that the dry weight of the grain with seed rate of 105 kg per hectare Koohdasht the minimum dry weight of the same variety, seeding rate of 70 kg of grain per hectare. Grain Filling rate between 1. 504 to 1. 697 mg per day between 1. 496 to 1. 648 mg of seed per day and for interaction between 1. 363 to 1. 867 variety and seed rate mg per day was variable. Between 26. 37 to 29. 11 day time filling grain and seed rates between 26. 42 to 28. 79 days for interaction between 24. 43 to 30. 72 day variety and seed rate was fluctuating. It seems that in areas with climatic conditions with drought stress, use of varieties with higher grain Filling rate is preferable.
