摘      要：This paper dealed with the differences between albino and normal seedlings of Calamus nambarensis *** in terms of growth and *** families among 22 families were found to have one to three albinos,the percent of which varying from 0.4 to 2.2 percents,while the percent of albinos among all 22 families was about 0.7 *** number of albino leaves and the length of longest leaves were 1.9±0.3 and 22.32±3.49 cm respectively, which were less than that of 2.0±0.0 and 26.09±3.26 cm of normal seedlings,accounting for 95% and 85% of normal *** albinos hadn’t chlorophyll a,but some chlorophyll *** total content of chlorophyll was 0.02 mg·g-1FW, much less than that of 8.15 mg·g-1FW of normal seedlings, accounting for 0.2 *** photosynthesis active radiation（PAR） was 800 μmol·m-2·s-1 or （1 600） μmol·m-2·s-1,the photosynthetic rate of albinos was less than that of normal seedlings,accounting for about 20 *** data of net photosynthetic rate of albino evaluatde by the authors were also
