Distribution Characteristics of Physiological Parameters of Yunyan 77-4 Latex and Its Application in Physiological Diagnosis of Latex
Yunyan 77-4 cut by Yunnan Tianye Rubber Sales company was taken as the research object,and the contents of la-tex sucrose,inorganic phosphorus,mercaptan and total solids were determined,and the distribution characteristics of these four physiological parameters were analyzed.The results showed that the distribution of physiological parameters of the triploid rubber tree Yunyan 77-4 latex was the same as that of the diploid,which was normally distributed.The average val-ue of total solid content was 34.64％,which was concentrated in the range of 35％～48％.The average mercaptan content was 0.37 mM,which was concentrated in the range of 0.2～0.5 mM.The average inorganic phosphorus content was 21.52 mM,which was concentrated in the range of 15～25 mM.The average sucrose content was 14.64 mM,which was concen-trated in the range of 15～20 mM.The results of physiological diagnosis of latex showed that the overall rubber mining in-tensity of the rubber tapping garden was too high,and it was recommended to adjust the rubber mining intensity.
