| 摘 要： | 用回归和相关分析法对菠萝果重与营养器官的相关性进行了研究。结果表明:菠萝果重与茎叶重量的相关关系达到极显著水平。茎叶越重,果实就越大越重。果重与裔芽数、裔芽重量、吸芽数、吸芽重和冠芽重等营养芽均呈正相关,其中,果重与裔芽重关系最为密切,与裔芽数次之,都达极显著水平;但在排除茎叶重的影响后,对果重与营养芽的关系进行偏相关分析表明,果重与冠芽重、裔芽数、裔芽重、吸芽数、吸芽重均未达到显著的相关水平。在茎叶重一定的情况下,果重与裔芽数、裔芽重量和吸芽重及冠芽重的关系不大。不同菠萝种类、不同杂交种其营养芽的数量不等。大果类型其营养芽的数量明显少于小果类型,应是一种遗传特性;此外,裔芽与吸芽间存在负相关关系。因此,在菠萝生产中除芽是否能达到显著增产,有待进一步研究。

| Abstract: | Investigation results obtained in the showed that there was a significant correlation between fruit weight and stem-leaf weight. Plants having heavier stem-leaf weight tended to produce bigger and heavier fruit. The fruit weight also showed a positive correlation with various vegetative buds to varied degrees respectively. The correlation between fruit weight and slip numbers and weight reached a significant level. However, the partial correlation analysis of fruit weight and vegetative buds after eliminating the effect of stem -leaf weight did not indicate any significant correlation among them. Vegetative buds under the same stem-leaf weight condition did not affect the fruit weight. In the relationship between vegetative buds, slip number and weight showed negative correlation with sucker number and weight. The numbers of vegetative bud were quite different among varied types and hybrids of pineapple. Bigger fruit types tended to have less vegetative buds than smaller fruit types. It was doubtful that crown cutting and slip thinning could increase fruit yield significantly. |
