| 摘 要： | 经三年观察研究,十个不同熟性春谷品种的幼穗发育开始时间是随着它们生育日数长短而变化,并与拔节始期有着密切的关系.同时,春谷不同熟性品种的叶龄指数又与幼穗发育阶段呈回归直线关系.因此,春谷不同熟性品种利用其叶龄指数,求出适宜的系数,再代入改进的直线回归关系式,即可以较准确地判断出谷子的幼穗发育阶段.

| Abstract: | The 10 varieties of the spring millet of different life-periods have been studied in the past three years. Apparently, the starting time of ,the young ears development varied long or short with their life-period. They have had close relationship to the initial stage of the elongation. They also form a linear regression relation between the developmental stages of the young ear and the leaf -age index.If you use them to make out the proper coefficient and take them into the linear regression equation, then you can find out its developmental stage of spring millet. |
