研究不同产地间交趾黄檀种子形态与和发芽率间的差异,以期初步选出优良种质,为进一步的遗传改良提供基础。分别对引自泰国5个、柬埔寨4个以及中国1个次生产地的交趾黄檀种子进行形态测定和播种发芽试验。结果表明:交趾黄檀种子的长变异幅度为6.09~7.19mm,宽3.84~4.28mm,厚0.98~1.19mm;千粒重变幅为20.68~33.76g;发芽率最高的是泰-5达87%,最低的是泰-1为39%。不同产地的交趾黄檀的种子形态、发芽率均具有明显差异,因此引种来源有必要进行选择。
Variations of seed morphology and germination percentages of different producing area of Dalbergia cochinchinensis Pierre
The variations between seed morphology and sowing quality of different producing area of Dalbergia cochinchinensis seeds were studied elite germplasm to provide a foundiation for genetic improvement on D. cochinchinensi. We studied the shapes and germination of D. cochinchinensis seeds belonging to 10 prove-nances collected from Thailand, Cambodia and China. The results showed that its seed length ranged from 6.09mm to 7.19mm,the range of seed width is 3.84mm to 4.28mm, the seed thickness varied between 0.98mm and 1.19mm and 1000-seed-weight ranged from 20.68g to 33.76g. The highest germination rate was T-KI provenance with 87% and the least was T-PP provenance with 39%. Person correlation analysis showed that seed germination had a negative correlation with seed morphology characters,suggesting that seed size and seed plumpness maybe a factors affecting seed germination.
