Abstract :

In order to investigate the effect of drought on morphological characteristics of Anisum, a split plot experiment was conducted in 2011 at Research Station located in the Alborz mountains in Karaj by using a randomized complete block design in four replications. The main factors included 3 populations (Sabzevar, Kerman and Jiroft) and the operating subsidiary of 4 Stress levels (10, 30, 50 and 70 Percent moisture depletion). Results showed that the main effect (population) the number of umbrellas, leaf dry weight, seed weight and seed weight of the sub-agent (drought) on plant height, canopy diameter, small diameter, large canopy, umbrella number, root dry weight, stem dry weight, leaf dry weight, dry matter yield and seed weight showed a significant difference . The main operating subsidiary of interaction in small canopy diameter and number of umbrella in 1% And the dry weight and stem dry matter yield in 5% was significant. Comparison of the main factor (population) showed that the greatest number of umbrella with an average population of Jiroft 66.62 n/p, leaf dry weight with an average population of Sabzevar 198.543 Kg/ha of grain per hectare and an average population of Kerman 2.95 g/p were obtained. Comparison of the effects of sub-factor (drought) showed that the highest plant (48.91 Cm), the number of umbrella (81.83 n/p), root dry weight (91.778 Kg/ha), stem dry weight (577.725 Kg/ha), leaf dry weight (272.724 Kg/ha), dry matter (942.227 Kg/ha) and seed weight (3.20 g/p) obtained from 10 percent moisture depletion. 10% moisture depletion level was the best water level to produce the highest dry matter production.
