Following an initial inhibition under high PAR , growth and maximum quantum yield were stimulated , and heterocyst formation was enhanced and high PAR interfered with the normal pattern of heterocyst differentiation with contiguous heterocysts formed in filaments .

在强PAR照射下，最初发生光抑制，随后生长和最大光化学效率都逐步恢复，而且异形胞分化能力增强，并干扰了正常的异形胞分裂模式，使藻丝体中形成相邻异形胞。

Outer membrane of Anabaena and other cyanobacteria is the first barrier for nutrition uptake , and in Anabaena even affects the development of heterocyst envelope . But until now , few functional studies have been done about outer membrane proteins of cyanobacteria .

鱼腥藻和其他蓝藻的外膜是吸收营养物质的第一道屏障，在鱼腥藻中还可能直接影响异形胞包被的形成，但迄今为止，有关蓝藻外膜蛋白的功能尚缺乏研究。

However , only was the heterocyst frequency of the 9101 . ' 1 strain in the treatment of wheat and BG11 ( - N ) medium more obviously different than that in BG11 ( - N ) medium . The heterocyst frequency ranged from 9.45 % to 16.55 % .

与BG11（-N）相比，在BG11（-N）+小麦处理中，念珠藻中只有9101∶1的异形胞频率与BG11（-N）处理有差异，其异形胞频率为9.47～16.55%。
