红掌种子萌发特性的研究

以Toscane等红掌种子为材料，研究了红掌种子萌发特性。结果表明，红掌种子萌发是一个缓慢的过程，且萌发不整齐。基因型不同，红掌种子的萌发率不同。采用直播萌发试验，不同基因型黄种子的最高和最低萌发率相差83．18％。不同成熟度的种子萌发率不同，黄种子萌发率最高，干种子次之，青种子最低。萌发条件对红掌种子萌发有显著的影响，光照12h／d显著提高种子萌发率，变温条件下红掌种子的萌发率和萌发指数比恒温条件下高。

Study on Characteristics of Seed Germination of Anthurium andraeanum Lind.

Seeds of elite cultivars such as Toscane and F_(1) combinations were employed to investigate the characteristics of germination of Anthurium andraeanum seeds.The results showed that the germination of it's seeds was a slow process and uneven.The germination percentages of different genotypes were obviously different.Using direct seeding method,the difference between the highest and the lowest germination percentage of the yellow seeds was 83.18%.Seed maturity affected clearly seed germination capacity.The highest germination percentage was recorded in yellow seed followed by the dry seed,the green seeds had the lowest germination percentage.The culture condition had great influences on seed germination.The germination percentage was significantly improved under light,the germination percentage and germination index at alternative temperature were higher than that at constant temperature.
