菊苣软化栽培用的是种根,为提高菊苣球产量和品种,除选择适宜品种外,培育优质健壮的菊苣种根至关重要。通过对菊苣种根与芽球生长相关性的测定可知,菊苣芽球重与种根重虽没有相关性,但芽球重与种根粗度之间呈正相关。而且二者相关差异极显著。说明芽球重随根粗的线性变化而线性增加,因此,培育优质粗壮的肉质根对提高菊苣单芽球产量是非常关键的。
In order to improve the yield and variety of chicory bulb, it is very important to cultivate high-quality and robust chicory roots in addition to choosing suitable varieties. Through the determination of the correlation between the growth of chicory root and bud, we can see that there is no correlation between the weight of chicory bud and the seed weight, but there is a positive correlation between the weight of bud and the diameter of root. And the difference between the two is extremely significant. The results showed that the bud weight increased linearly with the linear change of root diameter. Therefore, cultivating high quality fleshy roots was very important to improve the single bud production of chicory.
