本文是在冬季采用二分之一树围与周割制对无性系RRIM600、PR107和GTl进行割胶,以研究冬割胶乳的某些生理参数。经过测定,RRIM600、PR107和GTl在此期间平均胶乳糖含量分别为0.45％、0.81％和0.64％;平均电导率(ms)分别是1.10、1.14和1.06;株次平均干胶分别是152.55克、123.46克和96.76克;平均干胶含量分别是42.49％、44.41％和45.82％;胶乳pH值分别是7.28、7.33和7.30;平均酚含量分别为97.21ug/ml、125.52ug/ml和103.32ug/ml。
In this paper, the clinker clones RRIM600, PR107 and GTl were excised in the winter by one-half tree circumference and week cutting to study some physiological parameters of winter cut latex. The results showed that the average lactose contents of RRIM600, PR107 and GTl were 0.45%, 0.81% and 0.64%, respectively; the average electrical conductivity (ms) were 1.10, 1.14 and 1.06, respectively; 123.46 g and 96.76 g respectively; the average dry gum content was 42.49%, 44.41% and 45.82% respectively; the latex pH values were 7.28, 7.33 and 7.30 respectively; the average phenol contents were 97.21ug / ml, 125.52ug / ml and 103.32ug / ml.
