Effect of auxin on growth, development and yield of two cultivars of peanut (Arachis hypogaea L.)
Subject Areas : Genetic
Keywords: Peanut, Pod yield, IAA, pod number,
Abstract :
The peanut plant from the Fabaceae family has many different cultivars. In this research the American cultivar and the local Gilan cultivar were choosen and planted under field conditions. The experimental design of the above research was Split plate test with completely randomized block design for growth regulators, with two treatments and a control. Treatments were six milligrams per liter IAA (a) and eight milligrams per liter IAA (b). The effect of hormone on the weight of hull and seed, the weight of the hull without seed, number of seeds in the hull, number of pegs on the plant showed that, the above mentioned factors had no significant effect, but the effect was noticeable on the development of peg into pod.In the local Gilan cultivar the development of peg into pod decreased but it increased in the American cultivar. In order to have an increase of the weight of seeds and pod yield, in the Local Gilan cultivar, low content of IAA should be applied, while in the American cultivar high level of IAA led to an increase of the weight of thousand of seeds and pod yield.
