摘要
坛紫菜孢子囊枝在形成过程中,从培养开始至第4周,3种色素(叶绿素a、类胡萝卜素和藻胆蛋白)的含量和蛋白质的质量分数逐渐上升,在第4周时达到某一最高值后逐渐下降;碳水化合物的质量分数和藻胆蛋白与叶绿素a的比值均一直呈上升趋势,它们与孢子囊枝数量之间呈较明显的正相关;碳水化合物与蛋白质的比值在培养前期略有下降,随着丝状体进一步发育(4周后),该比值逐渐上升。
The changes of several kinds of biochemical composition with sporangial branchlets formation of Porphyra haitanensis weres studied. The results showed that protein content and 3 kinds of pigment （chlorophyll-α, carton and phycobiliprotein ） were increasing gradually and reached a maximum in first 4 weeks. Carbohydrate content and the ratio of phycobiliprotein and chlorophyll-α were increasing in the all process. The ratio of carbohydrate and protein had fallen a little at first and then increased because of some metabolic products accumulating faster than pigments and protein, which had no relativity with sporangial branchlets in quantity.
