摘要：

Moss protonemal growth direction is controlled by at least three factors, photo-, gravi- and autotropism..It is possible to experimentally separate these factors and to control selectively their morphological appearance. In darkness protonema grow negatively gravitropically, and unilateral illumination initiated positive phototropism. Red light suppressed auto- and gravitropism, blue light suppressed only gravitropism. Green light allowed both gravi- and autotropism. The effect of light on gravitropism might involve changes in starch synthesis. (C) 1998 COSPAR. Published by Elsevier Science Ltd.
