Abstract:
Seed morphology and germinating characteristics were studied in 5 genotypic Rhododendron (R.pulchrum ‘Meihong’,R.simsii,R.championiae ‘Fenhe’ ‘Shenqiuhong’ 3 cultivars and R.molle,R.simsii 2 wild species) in Hubei Province,to provide reference for seedling introduction and breeding of new variety.The results showed that the seed of tested Rhododendrons were generally very small,but the seed of Rhododendron molle was significantly bigger than the others.The 1 000-seed weight of Rhododendron molle was the highest,0.258 g,while that of R.pulchrum ‘Meihong’ was the lowest,0.051 g.Seeds of different Rhododendrons were nearly ovate,elliptic,or oblong.Moreover,wing and surface striation of seed showed taxonomically useful variation in tested Rhododendrons.The germination time of R.molle was the shortest,10 days,while that of R.simsii was the longest,15 days.The germination rate (GR),germination energy (GE) and germination index (GI) showed that R.molle>R.championiae ‘Fenhe’>R.pulchrum ‘Meihong’>R.simsii ‘Shenqiuhong’>R.simsii.
