| 英文摘要 | The effect of three seedling treatments: t-0, normal germination; t-1, cotyledons removed; t-2, cotyledons removed 5 days earlier than in t-1; and two phosphorus levels (p-0 and p-30) on nodulation and nodule function in soybean [glycine max (l.) merr] were investigated in nutrient solution culture. the number of nodules formed at p-0 was in the order t-2 > t-0 > t-1, but it was t-0 > t-2 > t-1 at p-30, nodule dry weight per plant had the same tendency as the nodule number. nodule size (dry weight per nodule) in seedlings ranged from 0.601 to 1.089 mg in the order t-0 > t-1 > t-2, regardless of p level. for example, nodule size in to was larger by 86% and 52% than t-2 at p-0 and p-30, respectively. furthermore, regardless of p level, a specific acetylene reduction activity (ara, mu m c2h4/h/g nodule) increased with p content in seedlings, but no significant difference was found (p < 0.05). leghemoglobin (lb) content was not significantly affected by p level; however, seedlings (t-0 and t-1) significantly affected the lb content per unit plant biomass (p < 0.05). all these results suggest that seedling p content plays a key role in nodulation and nodule function of soybean. |
