【摘要】 一红串品红种是在中田国间夏自秋然季高节温常下用的的生红育色期草及花田,间温生度长超指过标30的℃变会化严情重况影。响结其果观表赏明价一值串。红试不验同研品究种了间9在生育期上存在显著差异,火娃和辉虹开花天数最长。在自然高温胁迫条件下,一串红不同品种间在株高、冠幅、花序长度和花序数上存在显著差异,所有品种生长放缓,并且均出现了少量叶片萎蔫的现象,但高温并未对一串红的正常开花起到显著影响。在整体表现上,辉虹、皇后、火娃和红孩表现出较高的观赏价值,有较强的耐热性,适于在高温下生长。

【Abstract】 Salvia splendens , a red bedding plant is used widely in landscape in the Summer and Autumn. High temperature exceeding 30℃ will seriously affect its ornamental value. The change of development stage and growth indexes of 9 Salvia Splendens after high temperature treatment was investigated. The seedling experiments were performed in farmland under natural high temperature. The results showed that there are significantly different in growing period ofSalvia Splendens under natural high temperature."Huo Wa"and "Pround Red"had the longer florescence. Plant high, rown diameter, inflorescence length and inflorescence number of nine varieties were significantly affected by high temperature stress and showed significant differentce in varieties. The tests also found that all the varieties of growth slowed down and there were a small number of leaves wilting. However, high temperature did not affect the flowering ofSalvia Splendens . On the whole ,"Pround Red","Queen","Huo Wa"and"Hong Hai"were tiptop in visual value and heat-tolerance.
