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.]]>Almekinder, C.J.M., A.S. Chilver and H.M. Renia,199639289303Baraldi, R., F.F.F. Malavasi, S. Predieri and M.
