摘要
鸡爪槭品种为世界著名的秋叶树种,夏季易遭受热胁迫而影响观赏效果。为研究13个常见鸡爪槭品种的耐热性,通过人工气候室模拟高温环境进行胁迫试验,测定了鸡爪槭不同品种的半致死温度。同时,通过分析各品种叶片中的叶绿素、花青素含量,研究鸡爪槭品种耐热性与花青素和叶绿素含量的相关性。研究结果表明,随着温度上升,13个鸡爪槭品种致死率均体现出"S"形上升趋势,不同品种对高温的耐热性差异明显。13个品种的耐热性依次为舞森>红枫>血红鸡爪槭>金叶鸡爪槭>早乙女>小鸡爪槭>红鹤>青紫姬>流泉>赤枫>茜>海塞>蝴蝶。相关性分析结果未能证明鸡爪槭品种的耐热性与叶绿素、花青素含量有显著相关性。
Acer palmatum is a famous species in the world for its beautiful autumn leaves.In order to study the heat resistance of 13 varieties of A.palmatum,their semi-lethal temperature was determined by the stress test in a artificial climate chamber.And the correlation between semi-lethal temperature and anthocyanin content,as well as chlorophyll content was studied.The result showed that the death rate of 13 varieties expressed an S-shape trend with the rise of temperature,but the resistances of different varieties to high temperature were obviously different.The heat resistance of 13 varieties was in such an order as A.palmatum‘Mai mori >A.palmatum‘Atropurpureum’ >A.palmatum‘Bloodgood’ >A.palmatum‘Aureum’ >A.palmatum‘Saotome >A.palmatum var thunbergii >A.palmatum‘Benizuru’ >A.palmatum‘Arano’ >A.palmatum‘Ryu sen’ >A.palmatum‘Sango kaku’ >A.palmatum‘Akane’ >A.palmatum‘Higasayama Broom’ >A.palmatum‘Butterfly’.The results of analysis showed no significant correlation between the heat resistance and the chlorophyll content,as well as the anthocyanin content.
