Abstract:

The effects of density regulation and rotation harvesting shoot on the shoot and young bamboo growth were studied under the different experimental treatments.The results indicated that:①The number of 1 year old daughter ramets in the treatment of 4～5-year-old mother ramets cutting was 1.92 times over that in the no cutting treatment; ②The rotational harvesting shoot improved the growth of daughter ramets, so the growth increments in height and diameter of 1 year old ramets were 1.5 and 1.4 times than those without treatment; ③There was a tend that the daughter ramets become short under the condition of current annual shoot picking.

Key words: Qiongzhuea tumidinoda, Clonal growth, Physiological integration, Density regulation, Rotational harvesting shoot
