为了精确迅速地评价甘薯育种材料,采用农艺性状结合生理分析可以充实鉴定内容。1.生产力鉴定中,在一般产量比较的基础上应该进行有关光合作用、生长分析等鉴定。2.鉴定株型不仅限于形态结构的区别,还要研究叶片排列与利用光能的关系。3.通过栽插期试验和块根增长速度的分析,可以明确不同材料的季节型。4.通过根系生长、原生质粘度、叶片组织持水力等方面的测定,可以辅助耐旱性鉴定。
In order to evaluate the sweet potato breeding materials accurately and quickly, agronomic traits combined with physiological analysis can enrich the identification. 1. Productivity identification, the general output should be based on the comparison of photosynthesis, growth analysis and other identification. 2. Identification of plant type is not limited to the difference between the morphological structure, but also to study the relationship between leaf arrangement and the use of light energy. 3. Through the pot experiment and root tuber growth rate of analysis, you can clear the different types of seasonal materials. 4. Through root growth, protoplasm viscosity, leaf water holding capacity determination, can help identify drought tolerance.
