| 摘 要： | 对苦竹Pleioblastus amarus 生长发育规律进行了初步研究。结果表明:苦竹发笋盛期是5 月12 日至5 月20 日, 出笋规律呈偏正态分布。苦竹退笋率为41.21 %。退笋的主要原因是营养供应不足。苦竹秆形高生长可分为4 个时期:初期15 d , 日生长量1 ～ 3 cm ;上升期10d , 日生长量7 ～ 20 cm ;盛期20 d , 日生长量可达45 cm;末期5 d , 日生长量迅速下降, 直至停止。苦竹秆形高生长呈Logistic 增长, 昼夜高生长量变化不甚明显, 在昼夜24 h 出现3次生长高峰。图3 表4 参9

| Abstract: | The rhythm of growth and development of Pleioblastus amarus were studied .The main results were as follows: (1)The prosperous period of appeared bamboo shoot was in the middle ten days of May . (2) The percentage of shoot degradation was 41.21 %, mainly because of nutrient deficiency . (3) The height growth of young culm could be divided into four stages :initial stage , ascending stage , boosting stage and terminal stage . (4)The height growth of young culm followed logistic curve .(5)The increment of young culm of night was close to that of daytime , and three growth peaks appeared during 24 h .
