- 摘要:
- 以“香梨”ד早酥梨”20株杂交后代为试材，调查了其果实性状和营养枝不同叶序叶片性状，研究了其后代果实、叶序叶片性状的分离变异及相关性。结果表明：“香梨”与“早酥梨”杂交后代果实、叶片性状广泛分离，变异程度高；1～6叶序叶片的长度、叶宽、叶面积随着叶序递增而增加，然后随叶序递增而减少，叶形指数随叶序增加而增大，以第4～6叶序变异最小；杂交后代果实单果重与纵横径呈极显著正相关；营养枝叶序第4～6叶片性状与果实单果重、果实纵横经之间呈显著正相关，可作为标准叶建立相关回归方程预测果实大小。
- Abstract:
- Taking 20 plants of ‘Fragrant pear’ and ‘Early crisp pear’ hybrid as materials，fruit characteristics and different phyllotaxis blade in foliage branch were investigated，the dissociation and correlations between fruits of hybrid pear and phyllotaxis leaf traits were studied.The results showed that the leaf and fruit characteristics were separated widely，and had high variation.The leaf width，leaf length，leaf area of the first phyllotaxis leaf to the sixth phyllotaxis leaf increased，and then the leaves got shorter，narrower and smaller as phyllotaxis increased progressively，but leaf index increased as its phyllotaxis increased progressively.Besides，the variation from the forth phyllotaxis leaf to the sixth phyllotaxis leaf were the smallest.Single fruit weight was significantly positively correlative with fruit vertical diameter and fruit horizontal diameter；leaf character of the forth phyllotaxis leaf to the sixth phyllotaxis leaf in foliage branch was significantly positively correlative with single fruit weight，fruit vertical diameter and fruit horizontal diameter，indicated these leaves may be used as standard leaves to set up the regression equation for predicting fruit size.
