Abstract:

Six soybea n v arieties, of w hich fiv e hav e the o rigin of high-ati tude a nd co ol regiono f Heilo ng jia ng , China, w ere int roduced to the inv estig atio n to observ e thei r perfo rmance of t ro pical /subt ro pical-conditio n induced shriveled seeds uneler dif ferent w aterlo ss ra tes. From the study and o ther fo rmer obesrva tio ns, w e find tha t it i s common fo rsoybean v arieties dev elo ped in hig h-lati tude and cool a reas, i f planted in tro pical o r subtropical a reas, to yield a large number of shriv eled seeds. These seeds are ex t remelyw eak in germinatio n and emergence abi li ties. Therefo re, it is v ery dif ficul t to introducesoybean va rieties f rom hig h-lati tude /co ol regio ns to tro pical /subt ropical regio ns for bothproductio n a nd germplasm purposes. There is v ery sig ni fica nt va riation of ratios ofshriv eled seeds among va rieties ra nging f rom 7. 46 to 88. 68% under normal w ater lo ssra te, 10. 29 to 93. 27% under accelera ted w ater loss rate and 0. 57 to 87. 1% under slow ed w ater loss rate. Accelera ted w ater lo ss rate ca n obv iously increase the number ofshriv eled seed of most so ybean v areties, a nd slow ed w ater lo ss ra te can ef fectiv ely decreaseshriv eled seeds. When combined w ith adequate sow ing time, slow ed w ater lo ssra te can reduce shriveled seed rate f rom as hig h as 76. 67 to as low as 10. 58% . lt w asconcluded that w ater loss ra te, influenced by soil moi sture, atmosphere humidi ty andva ria tion of w ater-ho lding abi li ty amo ng v arieties, w as the mo st impo rtant and di rectfacto r tha t resul ts in the fo rmation of shriv eled soybea n seeds, a nd t ro pical / subt ropicalva rieties might hav e st ronger abi li ty of w ater-holding than tho se of v arities developed inhigh-lati tude /cool areas.
