Photosynthetic Characteristics During the Formation of Reproductive Tissues of Porphyra Katadai var.Hemiphylla
摘要
Abstract
In this study, chlorophyll fluorescence parameters (Yield, Fv/Fm) and oxygen evolution were followed during the formation of reproductive tissues when female vegetative tissues (FV) and male vegetative tissues (MV) of Porphyra katadai var. Hemiphylla were cultured indoor (5 ~20℃, 10 and 80 μmol/( m2 ? S)) for 20 days. At the same time, development of these tissues in culture was observed by microscope. The formation of reproductive tissues was closely correlated with the decreasing of photosynthetic activities. At the same temperature the tissues cultured under 80 μnol/ (m2 ? S) showed a greater extent of maturation than those under 10 μnol/ (m2 ? S) did, whereas their decreasing degree of photosynthesis was also larger. Under the same light intensity the extent of maturation ascended with our increasing temperature. At the same time photosynthetic activity of MV culture was the highest at 10℃ and the lowest at 20℃ , but the decreasing degree of photosynthesis of FV culture was smaller at higer temperature.关键词
