| 摘 要： | 通过对4个秋眠型不同标准秋眠级美国苜蓿品种生长高度的测定,研究了北京地区苜蓿春季第一茬草和秋季再生草的生长性状与自然光照时间的关系.结果表明:4个秋眠型品种均存在明显的自然光周期规律,春季长日照条件下生长发育迅速,秋季短日照下再生趋缓,并呈不同程度的休眠.春季第一茬草盛花期前,各秋眠型品种生长速度逐步加快,增长趋势相同,株高与日照长度呈极显著正相关,各秋眠型间株高和生长速度的差异均不显著.在秋季日照缩短过程中,不同秋眠型品种再生株高与H照长度极显著负相关,4个秋眠型品种的再生株高差异极显著(P＜0.01)；再生株高顺序为极非秋眠型(UC- 1465)＞非秋眠型(Pierce)＞半秋眠型(Archer)＞秋眠型(Maver-ick)；其再生速度曲线与春季的曲线不同. |

| Abstract: | The four standard fall dormancy alfalfa varieties from the U.S.A were used as materials,the growth height of the first stubbly grass in spring and the regenerative grass in fall were measured in Beijing area in order to find out the relationships of growth height with sunshine time.The results showed that the four fall dormancy varieties presented obvious natural photoperiod laws,they grew rapidly in the long-day conditions in spring.The varieties showed slow regeneration in the short-day conditions and sho... |
