热研 7- 18 - 5 5具有速生性状 ,开割前年均茎围增量 6 .83cm ,略高于对照 (PR10 7,下同 ) ;开割后年均茎围增长 2 .0 1cm ,极显著高于对照。早期产量表现也较好 ,前 8割年年平均干胶产量 12 31.9kg/hm2 ,略高于对照。 14割年年均干胶产量 1192 .5kg/hm2 ,为对照PR10 7(14 80 .5kg/hm2 )的 80 .5 5 %。再生皮和原生皮的生长速度均与对照相当。干胶含量偏低。该无性系在抗风性能上显著比对照差 ,死皮停割率高于对照。
Hot research 7- 18-5 5 with fast-growing traits, the average annual stem circumference increment before cutting 6 .83cm, slightly higher than the control (PR107, the same below); cut the average annual stem circumference after the increase of 2. 0 1cm, pole Significantly higher than the control. Early yield performance is also good, the first eight cut annual average dry glue production 12 31.9kg / hm2, slightly higher than the control. The annual average yield of dry cuttings was 1192.5 kg / hm2, which was 80.55% of the control PR10 7 (14 80.5 kg / hm2). The growth rates of both regenerated and native hides were comparable to those of the control. Adhesive content is low. The clones had significantly lower wind-resistant performance than the control and dead-skin cut-off rate was higher than that of the control.
