A study on growth regular pattern of Oligostachyum oedogonatum in shooting period
摘要
Abstract
The growth regularity of Oligostachyum oedogonatum in shooting period was analyzed by investigating its process of bamboo shoots and the young bamboo.The results showed that the shoot emergence of Oligostachyum oedogonatum began from mid-April and lasted about 45 days; few shoots emerged at the preliminary stage of shooting,this situation lasted about 3 days,and the shooting quantity accounted for 7.42% of the total shooting quantity; more shoots emerged at the prosperous stage of shooting,this situation lasted about 15 days and the shooting quantity accounted for 77.48% ; fewer shoots emerged at the last stage of shooting,this situation lasted about 27 days and the shooting quantity accounted for 15.10%.Pest was the most important factor of shoot degradation and the degraded shoot quantity accounted for 73.78%,the average rate of bamboo shoot becoming young bamboo was 64.03%.The height growth of all cohorts fitted to the sigmoid curve,which can be well described by Logistic equation,and the inflexion appearing time of each curve was the key growth period.The culms of the earlier cohorts were constantly higher than that of the later ones.关键词
