项目摘要

Influence of fruit position and the combination of 3 flowers with or without pollination in a baring shoot on seedless fruit drop or parthenocarpic fruit set of kaki (Diospyros kaki L.f.) cvs. Fuyu and Hiralanenashi was investigated to clarify the relation between parthenocarpy and competition for assimitates among fruits. 1. Fruit set of pollinated and non-pollinated flowers was the highest at upper position and lowest at basal one in a shoot. 2. Parthenocarpic fruit of upper position in the shoot of all pollinated. 3. More seeded fruits had a tendency to set higher than parthenocarpic fruits in the same shoot with flowers pollinates and non-pollinated. 4. Parthenocarpic fruit set in the shoot of all flowers non-pollinates, especially at the upper position, decreasing length of shoot. 5. These was significant difference in seedless fruit growth among the fruit positions, and many of the smaller fruits tended to abscise. 6. Parthenocarpic fruit set varied in fruit position and presence of pollinated fruit in a shoot, and the variation patterns of parthenocarpy were very similar in 'Fuyu' and 'Hiratanenashi'. We concluded that 1) a dominant factor of parthenocarpy in 'Fuyu' was more evidential than hereditary, 2) these was no remarkable difference in hereditary characteristic of parthenocarpy between 'Fuyu' and 'Hiratanenashi' and 3) fruit drop of seedless fruit was induced by the competition among fruit, and the parthenocarpic fruit set was resulting from relative advantage in sink strength among competed fruits.

果实位置的影响以及3只花的组合在裸露的水果滴剂或parthenocarpic果实的kaki（Diospyros kaki L.F.）CVS中的肉芽果中的组合。对Fuyu和Hiralanenashi进行了研究，以阐明parthenocarpy与竞争与果实的竞争之间的关系。 1。授粉和非花授粉花的果实是上部位置最高的，而在芽中的基础上是最低的。 2。在所有授粉的芽中具有上位置的parthenocarpic果实。 3。种子果实的趋势趋于在同一芽中用花授粉和非授粉的同一芽中的parthenocarpic果实设置。 4。parthenocarpic水果在所有花朵的芽中设置为非授粉，尤其是在上部位置，减少了芽的长度。 5。这在果实位置之间的无种子果实生长显着差异，许多较小的水果倾向于脱落。 6。par果实的果实套件在芽中的果实位置和授粉果实的存在各不相同，在“ fuyu”和“ hiratanenashi”中，parthenocarpy的变化模式非常相似。我们得出的结论是，1）“ fuyu”中par骨的主要因素比遗传性更为明显，2）在“ fuyu”和“ Hiratanenashi”和“ Hiratanenashi”之间的骨parthenokoarpy的遗传性特征上没有显着差异，而无酸的果实降低了。根据水果之间的竞争，以及parthenocarpic的水果集是由于竞争水果之间的水槽强度的相对优势而产生的。
