Tobacco seeds are very small. This causes difficulty in sowing and resulted in uneven seelings.This experiment aimed to study types and concentrations of hormones for proportion of pelleting tobacco seeds. The experiment was conducted at laboratory of seed quality testing section, Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. The Virginia tobacco seeds were pelleted with pumice, fillers material at the rate 150 g and used hydroxypropyl methylcellulose (HPMC) with concentrations 4 percent by weight as binder material. Two types of hormones, Gibberellin (GA) and Indoie-3-butyric acid (IBA) with four different rates 1, 2, 3, and 4 ml per 3 g of tobacco seeds were used. The tobacco seeds were pelleted by pellet-machine model SKK10. The... |
