摘要
为筛选出耐晒性较强的山茶花品种,以烈香、六角大红、克瑞墨、金花茶、五色赤丹、迪斯 6 个品种为试验材料,研究不同光照强度(全光照、遮阴率 50%、遮阴率 70%、遮阴率 90%)对植物形态指标及叶绿素含量的影响.结果表明,从生长特性、叶绿素含量、生物量积累等方面来看,全光照条件下品种迪斯、克瑞墨的生长表现最好,不同程度的遮阴处理均影响各品种的生长.最终筛选出品种迪斯、克瑞墨作为耐晒性较强的山茶品种.
Abstract
In order to screen out the varieties of Camellia japonica with strong sunlight resistance,the effects of different light intensity(full light,50%shade,70%shade and 90%shade)on plant morpho-logical indexes and chlorophyll content were studied with six varieties of Strong Fragrance,Hexagonal Red,Kremer,Jinhuacha,Wuse Chidan and L.T.Dees as experimental materials.The results showed that from the aspects of growth characteristics,chlorophyll content and biomass accumulation,the growth performance of L.T.Dees and Kremer under full light was the best,and different degrees of shading treatment would affect their growth.Finally,L.T.Dees and Kremer were selected as Camellia japonica varieties with strong sunlight resistance.
