Abstract:

Through field test s and observ ation in 3 years, comparativ e studies w ere made onf low ering , pod set ting a nd seed filling of three so ybean va rieties w ith dif ferent poddinghabi ts ( Tiefeng No. 24, determina te; Liaodou No. 10, semi- determina te; Shendou H- 5064, indetermina te) .The time of ini tial flow ering o f Tiefeng No. 24 cocurred at 69 day s af ter emergency ,and it flow ered fo r 18. 5 day s, ini tial f low ers a ppeared o n the middle part of the mainstem, then o ther f low ers bloomed g radually up and dow n along the stom. The time ofini tial f low ering of Liaodou No. 10 o ccured a t 54 days af ter emerg ency, i t w as 34 days off low ering season, the f low ering o rder w as basically from the low er to the upper. Thetime of initial f low ering of Shendou H- 5064 occured at 55 days af ter emergency , i t had40. 5 days of f low ering seaso n, the f low ering order was just the same as that of LiaodouNo. 10. The rate o f pod set of Tiefeng No. 24 was 33. 53% , the ra te o f pod set of mainraceme w as 36. 84% , those o f subraceme and branch w ere 48. 94% , 20. 29% respectiv ely, the main posi tio n at w hichpo ts set was on the upper par t of the main stem; w hilethose o f Liaodou No. 10 w ere 35. 75% , 55. 81% , 25. 00% a nd 0, the main position atw hich po ts set wa s on the middle pa rt o f the main stem; tho se of Shendo u H-5064 were 24. 00% , 35. 92% , 12. 12% and 6. 67% , the pods w ere dist ributed ba la ncelyalo ng the plant. The pod set ting Tiefeng No. 24, Liaodou No. 10 a nd Shendou H- 5064increased faster f rom 10 days to 16 days, 12- 21 days and 15- 26 da ys af ter f low eringrespectiv ely , and reached the giv en leng th a nd width w ere approximately the same. Thethree v arieties have a simi lar period o f pod g row th ( 63 da ys approx imately ) . The seedw eight accumlations of the three v arieties co uld be model led by Logi stic equa tion. Thehighest ra tes o f seed w eight accumula tio n occo ured a t 49. 4, 53. 3 and 56. 6 da ys af terf low ering.
