摘要: 在经历了2013年冬季低温胁迫之后,根据寒害等级比较品种抗寒性差异,对4个菠萝品种‘金菠萝’(MD-2)、‘黄金菠萝’、‘巴厘’、‘卡因’进行了寒害调查。结果表明,这4个品种均受到不同程度的寒害,其中‘金菠萝’和‘卡因’的寒害等级较低,‘巴厘’和‘黄金菠萝’的抗寒性相对较弱,抗寒能力依次为‘金菠萝’>‘卡因’>‘黄金菠萝’>‘巴厘’。叶绿素的荧光特性决定作物的光合产量,为此,比较了不同菠萝品种的叶绿素荧光参数。‘金菠萝’的Fo和Fm均显著高于‘巴厘’,但是4个品种的Fv/Fm却没有显著差异。‘金菠萝’和‘黄金菠萝’均适合在江门进行推广种植,寒害等级和叶绿素荧光参数可以为抗寒品种筛选提供参考。

Abstract: Investigation of chilling damage on different pineapple varieties was conducted after the cold stress in 2013 in Jiangmen. The experimental materials included:‘MD- 2’,‘gold’,‘Comte de Parisand’and‘Smooth Cayenne’. The difference of cold-resistant characteristics of these cultivars was identified based on chilling damage degree. The results showed that the cold weather caused chilling damage to all cultivars, the chilling damage degree of‘MD- 2’and‘gold’were lower than that of the other two cultivars. The coldresistant characteristics of four pineapple varieties presented as‘MD- 2’>‘Smooth Cayenne’>‘gold’>‘Comte de Paris’. The chlorophyll fluorescence parameters were important to crop yield, therefore, the field experiment was conducted in order to compare them. The values of Fo and Fm of‘MD-2’were higher than those of‘Comte de Paris’. There was no significant difference among the values of Fv/Fm of the four cultivars.‘MD- 2’and‘gold’could be cultivated well in Jiangmen. The chilling damage degree and chlorophyll fluorescence parameters could provide references for cold-resistant varieties selection.
