| 摘 要： | 在大理州林业科学研究所试验基地分别对采集后贮藏8h、24h、48h、72h的美国山核桃穗条进行含水率测定，并用不同含水率的穗条进行嫁接试验。结果表明，穗条含水率对美国山核桃嫁接成活率有显著影响。穗条采集后贮藏8h含水率为33．45％，嫁接成活率为28．8％；贮藏24h含水率为32．65％，嫁接成活率最高，为61．3％；贮藏48h含水率为31．44％，嫁接成活率为43．8％；贮藏72h含水率为31．07％，嫁接成活率最低，为25．0％。穗条蜡封最佳时间为采集后1～2d。

| Abstract: | Cutting wood moisture content of Carya illinoensis stored for 8 h, 24 h, 48 h, 72 h were deter-mined respectively in test base of Forest Research Institute of Dali, and grafting tests by using those cut-ting wood also have been conducted. The results showed that the effects of cutting wood moisture content on grafting survival rate of Carya illinoensis were significant. Moisture content of cutting wood stored for 8 h was 33.45% , graft survival rate was 28.8% ; Stored for 24 h was 32.65% , graft survival rate was 61.3% ; Stored for 48 h was 31.44% , graft survival rate was 43.8 % ; Stored for 72 h was 31.07% , graft survival rate was 25.0%. one or two days after collection was the best time to wax seal for cutting wood, |
