Title
The effect of different planting dates on anatomy of the peduncle and grain yield of rice varieties in the North Khuzestan region
Authors
Abstract
This study investigated the effect of different planting dates (change of ambient temperature conditions) on the peduncle anatomy and function in rice for one year in the village located 70 km north of Ahvaz, during Eastern shavoor 48˚, 28˝, north latitude 31˚, 50˝This experiment was arranged as split plot based on Randomized Complete Block Designwith three replications. The main factor in the three levels of planting date (25 May, 9 June, 25 June) and Were allocated to sub plots Red Anbori varieties (long and short) and was Champa. The highest and lowest xylem and phloem were respectively the second and first planting date. The highest and lowest panicle`s height were respectively the first and third planting date. The highest and lowest yield was respectively the first and third planting date. Among the varieties, Champa, with an average of 3795.4 kg Per hecyare, had the maximum efficiency.
