剪除糯米糍荔枝冬季嫩梢對產生花序之效果

Effect of Inflorescence Formation on Lomitzu Lychee by Pruning the New Growth Occurring during Early Winter

糯米糍荔枝在秋後產生之營養小枝，抽悄時期愈晚者、休眠後產生花序百分率愈少。在本試驗時期之氣候情形下，至11月底新葉尚呈紅色之嫩梢有55.9%產生花序。如將嫩梢剪除，其下位小枝頂端有88.3%可產生花序。12月22日新葉尚呈紅色之嫩梢均不產生花序，但嫩梢剪除後，其下位小枝頂端產生花序者為0～32.4%，視小枝生長狀況而異，該下位直徑較大者，較易產生花序。

Flushes of Lomitzu lychee occurred after fall usually fail to developed inflorescence. The later the flush occurred the less the inflorescences developed. In this experiment, it was found the removal of the new growth in 30 November 1978 showed accelerating the bursting of the lateral buds under the removed growth when their young leaves still was in pink, and 88.3 % of the topped shoots developed inflorescences from the lateral buds, and it was 55.9 % inflorescence as compared with the new growths for check. While the removal of new growths were carried out in 22 December 1978, there were 0~32.4% of the topped shoots developed inflorescences depending on the nutritional status of the topped shoots; It showed that the stronger the topped shoots, the higher development percent of the inflorescences.
