摘要
为了确定生产上鲜食糯玉米适宜采收期,开展了研究。通过对2个鲜食糯玉米品种津农3和津农0802授粉后不同时期,研究籽粒中可溶性糖含量以及水分含量的变化,其中测定鲜果穗的穗长及穗粗采用直接测量法,测定可溶性糖含量采用蒽酮法,测定水分含量采用烘干法,结果显示在授粉后21～27天收获的鲜食糯玉米,可溶性糖含量与水分含量较高且稳定,此时收获的鲜食糯玉米口感较佳,适时收获。为鲜食糯玉米的适宜采收期提供了理论依据,并且可用于糯玉米的育种、生产和推广种植。
In order to determine the production of suitable fresh waxy corn harvest period carried out the study. Through study of different times after pollination soluble sugar content and grain moisture content change of two fresh waxy maize varieties ＇Jinnong3＇ and ＇Jinnong0802＇, while the method of fruit ear length and ear diameter by direct measurement, soluble sugar content using anthrone method, the moisture content using drying method. Results showed that 21-27 days after pollination fresh waxy corn harvest, soluble sugar content and moisture content were high and stable, this time waxy corn harvested fresh taste better and timely harvest. Suitable for the fresh waxy corn harvest a view to providing a theoretical basis and can he used glutinous maize breeding, production and promotion of cultivation.
