摘要
利用随机区组设计研究杂交松的百粒重和成苗率及其相关性,结果表明,不同组合的火加松成苗率之间差异不显著,而百粒重差异极其显著,火加松成苗率和百粒重之间的相关性不显著;湿加松种子百粒重和成苗率差异都极其显著,而且两者之间相关性达到显著水平(R=0.47)。湿地松×加勒比松的成苗率平均值(15.88%)低于火炬松×加勒比松的成苗率(23.22%),因此湿地松×加勒比松种子成苗率更低,需要重视杂交松的育苗管理。
Research on 100-seed weight, germination and their relationship of Pinus hybrids by randomized block design showed that germination rote of different combinations of P. taedaxP, caribaea had no significant difference while the 100-seed weight had significant difference, and the relationship between them had no close relation. Germina lion rote and 100-seed weight of different combinations of P. elliottiixP, caribaea had evident difference and close relation. The average germination rote of P. elliottiixP, caribaea （15.88%） was much lower than that of P. taedaxP. caribaea （23.22%）, thus making higher cost of seedling cultivation ofP. elliottiixP, caribaea.
