밤송이의 生態에 관한 硏究 = A study on the bionomics of the chestnut burs

국문 초록 (Abstract)

(1) 이 試驗에 使用된 樹今, 水勢에 잇어 中, 側花 어느것 이나 그 柱頭에 受粉이 되면 結實한다.
柱頭抽出後 21∼24일 사이에 受粉하면 結實하므로 밤은 長期間에 걸쳐 受精能力이 있다.
(2) 밤의 花柱數는 8個정도가 標準이나, 花柱를 制限하여 ⅓로 하여도 受粉만 되면 結實을 하며, 果實의 肥大, 生理的 落果에도 別 영향을 인정할 수 없었다.
(3) 밤가시(刺毛)의 硬化는 結實과關係가 있어 側果가 不結實인 경우는 그 部分의 밤송이의 發育이 不良하며 8月中旬까지도 刺毛는 密生학고 가시는 부드러웠다.

This study is the investigation on the bionomics of the chestnut burs. The results are these.
1. This experiment used in the three ago and three pauxr's middle or side flower were all bear fruit, if it was pollination on the stigma.
2, After pick out the stigma, it was to pollinate from 21th day till 24th day, the chestnut was bear fruit.
So the chestnut have pollination capacity for a long time. The standard number of the pollen tube of chestnut are eight, but the pollen tube length was limitted. It was ability fruit bear by pollination. There were not find out fat of fruits and June drops.
3. The hardness of chestnut burs was relation to bearing.
If it was not development chestnut burs. When the side flower was unfertilizer.
