晚香玉种球的评价标准

Evaluation Standard of Tuberose Bulb

为实现晚香玉的标准化生产,提出了种球质量的客观标准。利用生物统计的方法分别对晚香玉开花种球与繁殖种球进行了分析与评价,从种球的围径、整体感、饱满度、病虫害等方面各分成4个等级,并对四级分类的合理性进行了研究,确定了适宜天津地区种植的种球级别。

In order to realize the standard production of tuberose, the practical standard of bulb quality was suggested. Also, the mature and young tuberose bulbs were evaluated for classification by the methods of biostatistics. The bulbs tested could be divided into four groups or classes according to their characteristics such as circumference, (outward) appearance, plumpness of bulbs and resistance to diseases and insects. Furthermore, the reasons why the standard of four classifications is set up and which group of bulbs is the most acceptable to Tianjin are studied.
