Dynamic on Chlorophyll Concentration of Leaves Surface of Different Provenances of Phyllostachys heterocycla cv. pubescens

Through measuring chlorophyll concentration of leaves surface of nine provenances bamboo,results show that the order of chlorophyll a and total chlorophyll concentration from large to small is northern provenances,southern provenances and middle provenances,but the order of chlorophyll b concentration from large to small is southern provenances,northern provenances and middle provenances The time to peak chlorophyll concentration is different in various provenances In generally,the vary of chlorophyll concentration tends to low high low The relation coefficient are up to remarkable correlation between chlorophyll concentration and facts of chlorophyll content,water rate of leaf,water rate of twig,and D B H The ratio between chlorophyll a and b is remarkable correlation with longitude The relation coefficicent are up to remarkable correlation among various chlorophyll groups concentration
