对广东目前推广的 4个香蕉良种以及粉蕉和大蕉进行切片显微观察 ,并结合低温处理的电导率测定 ,结果表明 ,香蕉叶片组织细胞结构紧密度 (CTR值 )与品种的耐寒性密切相关 ,且具有相对的稳定性 ,可作为香蕉耐寒性的鉴定指标。供试品种耐寒力强弱依次为粉蕉、大蕉、威廉斯 (8818)、“巴西”、“93- 1”、广东二号 (6 3- 1)。
Four banana cultivars and banana plants and plantains currently popularized in Guangdong were observed by microdissection and combined with the conductance measurement of low temperature treatment. The results showed that the cell structure compactness (CTR) of banana leaves was closely related to the cold tolerance of the cultivars Related, and has a relative stability, can be used as a banana cold tolerance identification. The cold tolerance of the tested cultivars were as follows: powder banana, plantain, Williams (8818), Brazil, 93-1, Guangdong 2 (6 3- 1).
