摘要
以人参榕叶片为试材,研究了不同补光时长对贮运暗胁迫下人参榕叶片生长和细胞膜的影响。结果表明:不同补光时长处理的人参榕,随着贮运时间的延长,落叶率、黄化指数、丙二醛(MDA)含量、相对电导率(REC)均呈上升趋势。补光时间不同,上升的幅度也不同,总体变化趋势为补光时间越长,落叶率、黄化指数、MDA含量、REC增幅越小。比叶重(SLW)变化趋势相反。总体而言,光照8、10、12h/d植株贮运效果较好,考虑成本及灯管发热量,人参榕贮运时最适补光时长为8h/d。
Taking Ficus microcarpaleaves as material,the effect of different supplement lighting time length on growth and cytomembrane of Ficus microcarpaunder dark stress during storage was studied.The results showed that defoliation rate,chlorisis index,the relative conductivity(REC)and content of malonaldehyde(MDA)in leaves increased with the extension of storage time under different supplement lighting time length.But rising range was different among different treatments.The trend of defoliation rate,chlorisis index,REC and content of MDA in leaves increased less under the longer supplement lighting treatments.The trend of specific leaf weight(SLW)was opposite.In general,the supplement lighting time length of 8h/d,10h/d,12h/d were best.Considering about the cost and lamp calorific value,the fitter artificial light time of Ficus microcarpawas 8h/d.
