The Role of Peg Based Stimulants Application on the Production and Physiology Character of Clone Pb 260
Keywords:
Clone PB 260, Stimulant, PEG.Abstract
The research’s objective is to study the effect of PEG bases alternative stimulant to increase production and physiological character of Clone PB 260. This research was conducted at Sungai Putih Farm, Rubber Research Center, Deli Serdang Regency, Province of North Sumatera. The altitude is 25 m above sea level with Ultisol soil type. This research was to study the difference of production parameters g/p/s, inorganic phosphate, sucrose content, and Thiol. The results showed that the stimulants was significantly affect and increased production, but show no significant effect to increase the concentration of sucrose and Thiol. PEG application can also encourage increased production and inorganic phosphate although has no significant effect but increasing the levels of sucrose and Thiol. Combination of stimulants and PEG is increase on the production and inorganic phosphates parameters.
