| Abstract | ||
| This research was conducted – out at the greenhouse . department of field crops . college of agriculture and forestry . University of Mosul in 2008-2009 . This research including to studies in the design and analysis in which four doses of the growth regulator IAA (0. 250. 500 . 1000 PPm) . Were used in the way of soaking the seed before planting for a period of up to 12 hours. the second method used in this research as spraying with the same dose on the plant at the tellering stage for the durum crop wheat variety cham – 3 for the first study and with the variety of cham -6 in the second study. The results of the first study showed that the highest value obtained were from number of grains / spike and weight of grain (gram/pot) and weight of straw (gram / pot) and number of grains/ pot when used the concentration of 1000 ppm and the highest value for character of plant height in the control of treatment and the concentration of 1000 ppm and highest value for the character of number spike / pot were at the dose of 500 ppm. When used spray method. the results showed a significant increase in the number of grains / pot and number of grains / spike and grain weight ( gram / pot) on the method of soaking . where as there was no significant differences between the two methods in the rest of the studied traits. The second study revealed concentration at 1000 ppm gave a highest value for plant height . whereas there was no significant differences between all concentrations used for the growth regulator IAA for the other parameters. the plant height number of grains / pot . the number of grains / spike . weight of grain (gram / pot) . the weight of straw (gram / pot) . were significantly increased when used the spray method . on the other hand there was no significant differences between the methods for all other characters . | ||
