Effect of pretreatment of seed on the growth and yield of wheat

Influence of presowing treatments (Presoaking cycles) with gibberellic acid (GA₃ 10⁻⁶M) and cycocel (CCC 10⁻⁵M) and their combination (CCC 10⁻⁵ 10M+GA₃ 10⁻⁶ 10M) was studied on growth and yield of wheat cv. Lok-1 (Triticum aestivum L) and cv. Arnej (Triticum durum Desf.). CCC+GA₃ pretreatment was quite influential in increasing the growth and yield components followed by GA₃ in Arnej. The effects of CCC were not well pronounced. 1000-grain weight was not higher in pretreated seeds of both the varieties. However the beneficial effects decreased with the increase in the number of pretreatment cycles in both the varieties.
