- 摘要:
- 该研究观察了厚壳红瘤果茶果实和种子的形态，进行了种子萌发特性的研究。结果表明：果实球形，果皮厚可达16 mm，子房3～4室。坚硬的种皮对厚壳红瘤果茶种子的萌发影响明显，人工去除种皮对新鲜种子萌发有利；厚壳红瘤果茶种子不耐脱水，新鲜种子含水量高达51.28%，萌发率为100%，干种子含量为14.74%，萌发率为零；基质对厚壳红瘤果茶种子萌发的影响不明显，种子含水量是影响种子萌发的关键因子。
- Abstract:
- The fruit and seed morphology of Camellia rubituberculata were observed，germination characteristics of seeds were explored in this paper.The results showed that Camellia rubituberculata had globose capsule，pericarp thick 16 mm，3-4 locular.Hard seed coat influenced germination，getting rid of seed coat promoted germination percentage of fresh seeds.The seeds of Camellia rubituberculata were not desiccation tolerant，water content of fresh seeds were up to 51.28% and germination rate was 100%，dried seeds water content was 14.7% and germination rate was zero.Effect of different soil types on germination percentage of Camellia rubituberculata seeds were not notable，water content was a crucial factor on seed germination of Camellia rubituberculata.
