Evaluation of Potassium Humate Effects on Germination, Yield and Yield Components of HPS-II/67 Hybrid True Potato Seeds Under in vitro and in vivo Conditions
D. Hassanpanah and M. Khodadadi

Abstract:
This experiment was done for evaluation the effects of potassium humate on seed germination, yield and yield components and seed planting method to commercial used of F1 true potato seed. This research was conducted in Ardabil (Iran) during 2007 and 2008. HPS-II/67 hybrid seed 3500 were grown after treatment in seven different times by potassium humate (for 6, 12, 18 and 24 h till complete germination in potassium humate solution, till complete germination in water and without using the potassium humate and water as control). Potassium humate was used 40 mL kg-1 seed in 2 L of water. Then seeds were transferred to greenhouse and planted in peat mass bed (Biolan). During growth period were measured the traits such as start and seed germination percent and day number from planting till germination in laboratory and greenhouse. Seedlings transferred in 4-5 leaf stages to field. Experimental design was randomized complete blocks with three replications. After harvest, were measured the traits such as tuber number and weight per plant, tuber weight average per plant and tuber yield. Results showed that among different treatments of potassium humate there is significant difference for the tuber number and weight per plant, tuber weight average per plant and tuber yield. The maximum seed germination percent, tuber number and weight per plant, tuber weight average per plant and tuber yield produced in 6 and 12 h treatment by potassium humate. Direct planting of TPS in compare with the planting after seed germination in potassium humate and water caused to increase tuber yield. In this experiment, seed treatment by potassium humate for 6-12 h and seed direct planting in greenhouse percent without seed germination under in vitro, caused to increase seed germination percent and tuber yield.
