Abstract :
To investigate the effect of Triacontanol on the yield and yield components of the two chickpea Landraces, a randomized completely design in factorial experiment was conducted with three replications. The treatments designed as four levels of hormone consumption including 0, 5, 10 and 15 mg/l in the form of leaf and soil applications on two chickpea Landrace of Mashhad and Kermanshahi. The total treatments include 24 pots for each Landrace. In this experiment, traits such as grain yield, number of grains per plant, number of grains per pod and total biomass of chickpeas were estimated. Our results revealed that the effects of Triacontanol application, method of application on chickpea Landraces were drastically different. As well, the interaction effects on the yield and yield components were significantly different with an exception of the number of grains per pod. Increasing the doses of hormone by leaf application on Mashhad Landrace resulted in significantly elevating of yield and yield components of the chickpea. The triple interaction effects of Triacontanol application, method of application and chickpea Landrace in all treatments on measured traits were significant. In the triple interaction, the highest yield was observed by 15 mg/l Triacontanol application on the leaves of Mashhad Landrace chickpea, which increased the yield by 45% compared to control treatment. It was concluded that the increase of yield and yield components by elevated doses of Triacontanol application on leaves was mainly due to decreased rates of flowers, pods and leaves falling. On the whole, application of biochemical Triacontanol hormone resulted in increasing Chickpea yield by its positive effect on the metabolism activities of the plant.
