摘要
2002~2003年针对高油、高淀粉玉米品种与不同杂优模式普通品种的油分、淀粉积累动态进行了初步对比研究。结果表明:相对普通型品种类型,高油品种全灌浆期油分平均积累速率较高,完成全程油分积累进度较慢;不同杂优模式品种油分积累对比,显示出全灌浆期油分平均积累效率以“高油系×美杂”杂优模式较高,“Lancast-er×Reid”较低。从完成全程油分积累进度看,在中晚熟的3个杂优模式中,“Lancaster×塘四平头”较快,“Lancaster×Reid”较慢,在晚熟3个杂优模式中,“Lancaster×旅大红骨”较快,“美杂×高油系”较慢。高淀粉品种在全灌浆期淀粉平均积累的速率较高,而在完成全程淀粉积累进度上略低于普通品种。
In 2002 ~ 2003, oil content, starch accumulation trends of the high oil, high starch maize varieties and ordinary maize varietis in different heterosis patterns were compared and researched. The result showed: Relatively ordinary varieties, the oil accumulation speed of high oilmaize varieties is high in the whole grouting period, the whole accumulation progress finished is slow; the oil content accumulation of different heterosis patterns maize varieties demonstrated that the accumulation efficiency of oil content of'High oil department×Meiza'is high in the whole grouting period, that of'Lancaster×Reid'is relatively low. In the whole progress of finishing, the oil content accumulation, in the 3 heterosis patterns of medium-late maturity, that of'Lancaster×Tangsipingtou'is very fast,that of'Lancaster×Reid'is relatively slow, in the 3 heterosis patterns of late maturity,that of'Lancaster×Ludahonggu'is very fast, that of'High oil department×Meiza'is relatively slow; the starch accumulation speed of high starch varieties is relatively high, but lower than the ordinary varieties in finishing the whole progress of starch accumulation.
