不同地区茴香生长习性的比较研究

Study on Growth Behavior of Fennel from Different Areas

研究以产自宁夏海原、内蒙古托县、甘肃玉门、德国共4个地区的茴香(Foeniculum Vulgare)为材料在宁夏银川栽培,通过定期测定植株株高、最大叶长、最大叶宽、最大叶的小叶对数、全株干重,以及小花数、主花序径、小花序径、小花径等指标,对其生长习性进行了比较研究。结果表明,内蒙古托县和德国地区茴香的株高、全株鲜、干重等指标显著高于其他2个地区;开花最早的是宁夏海原地区的茴香,其次是甘肃玉门和内蒙古托县,德国茴香在调查期近8个月内并未开花。

Taking fennel seeds from Haiyuan in Ningxia, Tuoketuo county in Inner Mongolia, Yumen in t,ansu ana German as material, a comparative study of their growth habits were carried out through a regular determinations of the plant height, maximum leaf length and leaf width, froudlet logarithm of maximum leaf, whole plant dry weight, and the record of of floret number, the main inflorescence diameter, the small inflorescence diameter, florets diame- ter etc. The results showed that the plant height, whole plant dry weight and other growth index of fennel from Tuo- ketuo county in Inner Mongolia and the German region were significantly higher than the other two regions ; the earli- est flowering were the fennel of Haiyuan in Ningxia, followed by Yumen in Gansu and Tuoketuo county in Inner Mongolia, fennel from Germany did not blossom in the survey period nearly 8 months.
