图3 不同水稻品种不同种植季节籽粒灌浆和直链淀粉积累持续时间 Tf1、Tf2、Tf3定义同表4,Ta1、Ta2、Ta3定义同表2,每个形状的上限即为直链淀粉积累和籽粒灌浆各时期的结束时间,籽粒灌浆和直链淀粉积累的渐增期、快速期结束时间即为快速期和缓增期开始时间。1-4、6-9、11-14、16-19分别为2016年早季、晚季和2017年早季、晚季,同一种植季节内从左到右品种依次为陆两优996、中嘉早17、陵两优268和湘早籼45

Fig. 3 The duration time of amylose accumulation and grain filling with different rice varieties grown in different seasons Tf1, Tf2, Tf3 were the same as defined in Table 4, and Ta1, Ta2, Ta3 were the same as defined in Table 2. The upper bound for each trait was the end time of each period in grain filling and amylose accumulation, the end time of gradual and rapid increased period were the initial time of rapid and slowly increased period in grain filling and amylose accumulation. 1-4, 6-9, 11-14, 16-19 showed the rice grown in 2016 early and late season and 2017 early and late season, and the rice varieties were LLY996, ZJZ17, LLY268, XZX45 from left to right in the same growing season, respectively
