摘要

播时种子方位和播深对长叶麻种子萌发和幼苗活力的影响J.F.Macbr。被调查。在1.5、3.0、5.0 cm深的砂土盆中播种大小均匀的种子,采用直立(胚朝上)、水平和倒立三种胚位。实验采用完全随机分组设计。计算发芽率、初出天数、萌发速度、萌发指数、根冠长和干物质产量、活力指数I和活力指数II。竖置种子1.5 cm和3.0 cm时,种子萌发时间早、萌发率高,幼苗长势好,干物质产量高,活力指数I和活力指数II高。

Effects of seed orientation and sowing depths on germination and seedling vigour in Mahua (Madhuca longifolia)
Effects of seed orientation and depth at the time of sowing on germination and seedling vigour of Madhuca longifolia (J.Konig.) J.F.Macbr. were investigated. Seeds with uniform size were sown in sand filled earthen pots at 1.5, 3.0 and 5.0 cm depths, adopting three orientations of the embryo, viz., upright (embryo facing up), horizontal and inverted positions. The experiment was laid out in a completely randomized block design. Percentage germination, days taken for initial emergence, speed of germination, germination index, root and shoot length and dry matter production, vigour index I and vigour index II were calculated. Placing the seeds with the embryo in upright position at a depth of 1.5 cm and 3.0 cm resulted in early and higher germination, higher seedling growth, greater dry matter production and vigour index I and vigour index II.
