抗旱适应性的定量描述是甘薯品种抗旱性改良的基础工作。目前在甘薯品种抗旱形态指标筛选和抗旱适应性的生理机理方面只有少量研究,尚无抗旱适应性定量描述的报道。本文在测定六个甘薯品种十项抗旱形态生理指标的基础上,运用模糊数学关于隶属函数的方法对甘薯品种抗旱适应性的定量描述作了初步探索。
The quantitative description of drought tolerance is the basic work of drought resistance improvement of sweet potato varieties. At present, there are only a few studies on the physiological mechanism of sweet potato variety drought morphological characteristics selection and drought adaptability, and there is no report of quantitative description of adaptive drought resistance. Based on the determination of ten morphological and physiological indices of drought resistance in six sweet potato cultivars, this paper made a tentative exploration on the quantitative description of adaptive adaptability of sweet potato to drought using the fuzzy membership function.
