摘要
通过对16个玉米杂交种根系活力和根部形态性状的研究表明:玉米根系活力,特别是初生胚根和吐丝30d后的根系活力与产量成正相关;高产玉米杂交种初生胚根根系活力强,吐丝后根系活力下降慢;不同玉米杂交种的根层数相差不大,但气生根条数与产量成正相关。
The results of studies on the root activity and root characters of sixteen maize varieties showed that the root activity of newborn and 30d after silking was positively correlated with the yield. The high-yield maize varieties had higher root activity than that of low-yield and it declined slowly. The number of root layer between maize varieties was almost same, but the number of aerial root was difference and it was positively correlated with the yield.
