摘　　要：采用盆栽试验,研究水分处理对本溪山樱生物量的影响。结果表明:不同灌水量对本溪山樱实生苗产生影响不同,过量(每日灌1500mL)或少量(每日灌水量≤350mL)灌水时,植株生长发育不良,表现出水分胁迫状态;每日灌水量为750mL时,植株生长发育正常。随着淹没根系体积的增加,茎叶含水量、叶片相对含水量降低;全淹处理4d时植株死亡。The influence of moistre treatment on C.sachalinensis seedling biomass parameters were studied in pot experiment.The results showed that,the effect of different day-to-day water dosage on C.sachalinensis was difference. With the treating of excess dosage(day-to-day water dosage was 1500 mL)or lack dosage(day-to-day water dosage was≤350 mL),the growth and development of C.sachalinesis was restrained,and the plant showed the appearance of water stressed;With the treating of day-to-day water dosage at 750 mL,the biomass of the plant increased,the plant growed and developed normally.With the increasing of waterlogging volume in potted C.sachalinensis,the moisture content of stems and leaves,relative moisture content decreased,the C.sachalinensis,seedlings were death on the fourth day by the treating of whole waterlogging volume.
