通过引进的数学和数理统计概念及方法,对常异花授粉作物油菜和自花授粉作物水稻品种和杂交稻的品质产量有关性状的序列数据进行分析,揭示各性状潜在的规律。研究油菜种子物质积累过程表明除油份积累过程以外,其他物质的积累明显由自变量的3次函数决定,是一个非线性的过程。可溶性糖含量(SC),油份含量(OIL)和干物质(DW)序列的简单指数平滑模型都达到极显著水平,蛋白质(PRO)和纤维素(fible)线性模型都达到了极显著水平。但三磷酸腺苷(ATP)未达到显著水平,可见ATP作为许多物质代谢的基本能量供应者,参与的过程极为复杂,目前难以找到合适的数量模型。对水稻叶面积生长数据时间序列分析软件进行分析,结果与油菜种子数据具有明显的不同,油菜全是指数平滑和线性趋势模型,而水稻则在15个序列中,只有6个序列表现为指数平滑或线性趋势模型,其他全部为跳减趋势的指数平滑模型。除不育系模型比较特殊外,恢复系、杂种1代、多穗型品种、大穗型品种材料的单叶重都符合跳减趋势指数平滑模型。这个结果表明了水稻单叶重的基本变化规律。而且恢复系与杂交F1的模型在3个性状上都一致,用恢复系和不育系序列对杂交稻的序列进行模拟,都是以相应变量恢复系的作用为主,不育系的作用较小。说明在水稻叶片生长特性上,恢复系对杂交稻发挥决定的作用。
Through the introduction of the concepts and methods of mathematical and mathematical statistics, we analyzed the sequence data of traits related to the quality and yield of evergreen pollination rape and self-pollinated rice varieties and hybrid rice, and revealed the potential laws of the traits. Studying the process of rapeseed seed accumulation shows that the accumulation of other substances except the oil accumulation process is obviously determined by the cubic function of independent variables and is a nonlinear process. Simple exponential smoothing models of soluble sugar content (SC), oil content (OIL) and dry matter (DW) sequences all reached the extremely significant level, and both protein (PRO) and fible linear models reached extremely significant levels. However, adenosine triphosphate (ATP) did not reach a significant level. It can be seen that ATP, as the basic energy supplier for many material metabolism, is involved in a complicated process. At present, it is difficult to find a suitable quantitative model. Analysis of rice leaf area growth data time series analysis software, the results and oilseed rapeseed data have obvious differences, all the rapeseed exponential smoothing and linear trend model, and rice in 15 sequences, only 6 sequences showed exponential smoothing Or linear trend model, others are all exponential smoothing models of the trend of jump. Except for the male sterile line model, the single leaf weight of restorer line, hybrid 1 generation, multi-spike variety and large spike variety all fit the exponential smoothing model. This result shows the basic change rule of single leaf weight of rice. Moreover, the model of restorer and hybrid F1 was consistent in all three traits. The simulation of the sequence of hybrid rice with restorer and male sterile lines were based on the function of the corresponding variable restorer lines. The effect of male sterile lines small. Explain the growth characteristics of rice leaves, restorer lines play a decisive role in hybrid rice.
