对两组春小麦种子的谷氨酸脱羧酶的活性(GADA)做了分析,每组种子的GADA差异显著.将上述种子播于大田,观察到GADA与出苗指数呈正相关,而与成苗数呈负相关.出苗指数及成苗数与最终成熟株数有关,而最终成熟株数又与籽粒产量有关.因而可以认为种子的GADA与小麦的田间生产性状是相关联的. The activity of GADA in two groups of spring wheat seeds was analyzed, and the difference of GADA in each group of seeds was significant.The above seeds were sowed in the field, and it was observed that there was a positive correlation between GADA and emergence index, Negative correlation.The emergence index and number of seedlings were related to the final number of mature plants, and the final number of mature plants was also related to grain yield.Therefore, it can be considered that the GADA of seeds and the field performance of wheat are related.
