| 摘 要： | 以油食两用型芝麻新品种冀黑芝1号为试验材料，通过定株观测，分析其生长发育规律。结果表明：冀黑芝1号出苗后28～72d茎生长速度较快，其中，出苗后34～43d（即初花至盛花）茎日增长量最大（4．09cm），是整个生育期生长最快的阶段。从出苗至第1对真叶出现需要8d，之后叶片出现所需天数呈递减趋势，第10对真叶后1d分生1对真叶。叶面积系数变化趋势与茎生长规律一致，前期叶面积系数较小，盛花期达到最大（6．12），盛花期后又逐渐减小，成熟期叶面积系数维持在2．05，保留15对功能叶。始花后9d进入盛花期，日开花5．4—12．6朵／株，盛花期持续30d左右，该期开花量占总花量的84．8％，盛花后开花量迅速减少，日开花量维持在0．2～2．2朵／株。下部节位蕾从现蕾至开花需要6d，上部节位蕾需要3～4d。

| Abstract: | The rules of growth and development of new oil and edible sesame variety Jiheizhi No.1 were studied by fixed plants observation.The results showed that the stem grew rapidly 28-72 days after emergence,which grew most rapidly 34-43 days after emergence,the daily increase of stem was the most(4.09 cm).The first pair of true leave grew out 8 days after emergence,then the days for true leave growing out decreased.A pair of true leave grew out in one day after the tenth pair of true leave growing out.The change ... |
