黑暗条件下连续性干出对全缘马尾藻幼孢子体生长和生化成分的影响
Effects of Continuous Desiccation in Darkness onGrowth and Biochemical Constituents of Germlings ofSargassum integerrimum
摘要
Abstract
The effect ofdifferenttime (0.5 h, 1 h, 2 h, 4 h) desiccation in darknesson changes of germlinggrowth and content of chlorophyll a, chlorophyll c, carotenoid, proline and soluble saccharides ingermlings ofSargassum integerrimumwere investigated.Compared with control group without desiccation, resultsshow thatthe germlings growth of0.5 hdesiccation group and1.0 hdesiccationgroup wereaccelerated (P<0.05) and the content oftwo kinds of chlorophyll, carotenoid, proline and soluble saccharides in germlings of each group had no significant change(P>0.05). Meanwhile,resultsshow that the germlings growthof2 hdesiccation group and4h desiccation groupwereinhibited (P<0.05), two kinds of chlorophyll content in germlings of each group decreased significantly (P<0.05), the contentof carotenoid, proline andsoluble saccharides in germlingsof each group increasedsignificant (P<0.05)andit remainedat high level. Study suggests that 0.5 to 1h of continuous desiccation in darknesson the germlings ofS. integerrimum during seedling process on a daily basis has the effect of accelerating the growth of germlings. This treatment can also improve the stress resistance and adaptability to drought stress of germlings.关键词
