摘  要：
为明确芝麻种子发育过程中木酚素、粗脂肪、粗蛋白质的积累变化规律,以2个高木酚素芝麻品系SJ856、SJ857为材料,研究了其种子发育过程中木酚素、粗脂肪及粗蛋白质的积累变化情况。结果表明,随着芝麻种子逐渐发育,种子含水量不断下降,种子干物质积累量先近似直线上升后下降,授粉后35 d时积累量达最大值(干基千粒质量为2.99 g);粗脂肪、粗蛋白质积累与干物质积累同步,均先近似直线增加后下降,授粉后35 d时积累量均达最大值(1.633 5,0.690 0 mg/粒);芝麻素和芝麻林素积累量也随着芝麻种子逐渐发育而增加,在授粉后35 d时积累量均达最大值(17.103 4,6.134 1μg/粒),而后下降,呈前期积累快、中后期积累慢的特点,且芝麻林素的积累快于芝麻素。总之,在芝麻籽粒发育过程中,木酚素、粗脂肪、粗蛋白质积累变化趋势一致,均随种子发育呈先增加后降低的趋势,且均在授粉后35 d积累至最大值。

摘  要：
Two sesame breeding lines,SJ856 and SJ857 with high total lignans,were used to study the accumulation of sesamin,sesamolin,oil and protein during seed development. The results showed that moisture content of seed continuously decreased with seed development,and that seed dry weight,crude oil and protein increased approximately at a linear rate and reached their maximum( 2. 99 g,1. 633 5 mg / one-seed and 0. 690 0 mg / one-seed respectively) on the 35th day after pollination. Sesamin and sesamolin accumulated to their maximum( 17. 103 4 μg/one-seed and 6. 134 1 μg/one-seed respectively) on the 35th day after seed pollination,however,they increased much faster in early than in middle stages. Meanwhile,sesamolin accumulation was much faster than that of sesamin. In short,lignans,crude fat and crude protein share the same accumulation trend during the development of sesame seeds,they all increased first and then decreased during seed development,and accumulated to a maximum on the 35th day after pollination.
