A study of different type and proportion of polymers were investigated on tomato seed quality. This experiment was conducted at seed technology laboratory, Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. Using three polymers type polyvinyl pyrrolidone (PVP-K30), polyvinyl pyrrolidone (PVP-K90) and polyvinyl alcohol (PVA). This experiment consisted of 2 parts. The first part of experiment was to study effect of type and proportion of polymers as a film former on viscosity, dissolution of film-sheet. The second part, study the effect of seed coating substances on tomato seed quality. Seven treatments were compared: uncoated seed, seed coating with PVP-K30, PVP-K90 and PVA. The tomato seeds were coated by centri seed coater model SKK 10.... |
