| Abstract: | The
object of this study was to determine the effects of soybean cyst nematode (SCN) on
soybean growth, nutrient uptake by soybean and nutrient translocation in soybean. Soybean
was grown in plastic tube in greenhouse. The result indicated that the nodule number and
acetylene reduction rate was significantly lowed in SN14 infested with SCN,and the total root length of HF25
infested with SCN was significantly decreased. Infested with SCN, uptake of P by SN14 and
P translocation in HF25 were significantly decreased. Fig 4, Tab 2, Ref 7 |
