【摘要】 以茶藨属植物4个野生种和4个栽培品种为试材,采用石蜡切片方法,研究了低温胁迫前后叶片解剖结构的变化与抗寒性的关系。结果表明:叶肉细胞的海绵组织越厚、疏松度(SR值)越高、角质层越厚、栅栏组织细胞长/宽越高、栅栏组织层数越少,茶藨属植物抗寒性越强。更多还原

【Abstract】 Taking four wild species and four cultivars of Ribes L.as materials,the relationship between hardiness and leaf anatomy were studied with method of paraffin sections.The results showed that the thicker spongy tissue of mesophyll cells,the higher degree of SR,the thicker of cuticle,the higher length/width of palisade cells and the fewer layers of palisade had the greater cold hardiness of Ribes L..更多还原
