摘要
对来自秦巴山区6个野生百合种、4个栽培百合品种的组培生根苗进行高温(昼37℃/夜32℃)处理,以热害指数、叶片细胞膜透性和脯氨酸的含量作为指标对不同百合的耐热性进行了比较研究。结果表明:宜昌百合(L. leucanthum Baker)、Prato、山丹(L. pumilum D)的耐热较强,野百合(L. brownii F.E)、卷丹(L. lanci folium)的耐热性中等,岷江百合(L. regale Wilson)、Sorbnne、兰州百合(L. davidii var. unicelor)、Conca D′or、Siberia耐热性较弱。
Six species from Qin-ba Mountains and four cultivated varieties of Lily plantlets in vitro were treated with high temperature（day 37℃/night 32℃） and comparative studies on heat tolerance was conducted by observation the heat injury index and the measurement of leaf cell membrane permeability and proline content.The results showed that L.leucanthum Baker,Prato and L.pumilum D were the strongest tolerant to the heat treatment;L.brownii F.E,L.lancifolium were moderate tolerant, and L. regale Wilson, Sorbnne,l.. davidii var. unicelor, Conca Dor, Siberia were sensitive to heat.
