对以充实指数(饱满指数)作为定量指标估计小麦种子饱满程度的观点提出质疑:育种学家所谓的饱满度即指收获后干种子现实的皱缩程度,与充实指数并非同一概念。并提出以经验公式:V_D=2.0944l×0.5h×0.5w模拟长、宽、高分别等于l、w、h时的饱满种子体积(V_D)。在用排液法测定现实种子体积(V_G)后,以V_G与V_D之比值定义为种子饱满度(D),试验表明以D值度量的饱满度与目测种子饱满度级别顺序高度吻合。
The idea of using a full index (full index) as a quantitative indicator to estimate the fullness of wheat seeds is questioned: The so-called fullness of breeders, referring to the degree of shrinkage of dried seed reality after harvest, is not the same concept as the fullness index. The empirical formula is as follows: V_D = 2.0944l × 0.5h × 0.5w simulate full seed volume (V_D) with length, width and height equal to l, w and h, respectively. After determining the actual seed volume (V_G) by the drainage method, the ratio of V_G to V_D was defined as the seed fullness (D). The results showed that the plumpness measured by the D value was in good agreement with the visual seed plumpness order.
