A study on chlorophyll content dynamics and relation ship of new bamboo of Phyllostachys heterocycla cv. pubescens from different provenances

The chlorophyll content of the new bamboo leaves of Phyllostachy pubesens from nine provenances was measured and analysed. The results show that chlorophyll a, chlorophyll b and total content have similar changing patterns. All the Chlorophyll contents show a tendency of low-high-low in one year; among the nine provenances, the largest chlorophyll content is from Longhai, Fujian; the smallest is from Shangrao, jiangxi, the chlorophyll contents show remarkable difference in different bamboo provenances. The relation indexes are up to remarkable correlation among chlorophyll a, chlorophyll b and the total content.
