秋末冬初几种盆栽荷花休眠生理的比较研究

Comparative Study of Dormant Physiology to Several Potted Lotuses between the End of Autumn and the Early of Winter

采集秋末冬初阶段冬荷的两个品种‘雪里红’和‘傲霜’、碗莲品种‘红霞满天’不同时期的地下茎,对相关休眠生理指标进行测定.结果表明:过氧化物酶(POD)和多酚氧化酶(PPO)活性,可溶性糖,可溶性蛋白含量,游离脯氨酸(Pro)含量均呈上升趋势;其中同一时期下,各品种间POD和PPO活性、Pro和可溶性蛋白含量都达到极显著差异,且POD活性和Pro含量关系均为‘红霞满天’>‘雪里红’>‘傲霜’,PPO活性关系为前2个时期‘红霞满天’>‘雪里红’>‘傲霜’,后2个时期为‘雪里红’>‘傲霜’>‘红霞满天’,可溶性蛋白含量关系为‘雪里红’>‘傲霜’>‘红霞满天’;而各品种间同时期内可溶性糖含量达显著差异,且后3个时期冬荷的可溶性糖含量与红霞满天存在极显著差异,且糖含量关系为前2个时期‘红霞满天’>‘傲霜’>‘雪里红’,后2个时期为‘傲霜’>‘雪里红’>‘红霞满天.’

The acquisition and physiological index measurement of subterranean stem to winter lotus（＇Xuelihong＇ and ＇Aoshuang＇） and ＇Hongxiamantian＇ was determined at different periods of the end of autumn and the early of winter.The result indicated that the activity of POD and PPO,and the content of soluble protein,soluble sugar and Pro were rised;At the same time,as to different cultivars,the difference of the activity of POD and PPO,and the content of Pro and soluble protein was highly significant,the size-relationship of the activity of POD and the content of Pro was that ＇Hongxiamantian＇ was bigger than ＇Xuelihong＇,and ＇Aoshuang＇ was the smallest,and the activity of PPO of ＇Hongxiamantian＇was the largest at the first two periods,and ＇Aoshuang＇ was the smallest,at the last two periods,＇Xuelihong＇ was the biggest,and the smallest was ＇Hongxiamantian＇,the size-relationship of soluble protein content was that＇Xuelihong＇ was the biggest,and the smallest was ＇Hongxiamantian＇;The difference of soluble sugar content among different cultivars was significant,the difference of the last three times between winter lotus and ＇Hongxiamantian＇ was highly significant,and the size-relationship of soluble sugar content was that,at the first two periods,＇Hongxiamantian＇ was the biggest,and ＇Xuelihong＇ was the smallest,at the last two periods,＇Aoshuang＇ was the biggest,and ＇Hongxiamantian＇ was the smallest.
