摘要: 为提高木质化插穗生根质量,培育三角梅健壮扦插种苗,摸索培育优良种苗的扦插方法,比较不同生根剂、生根剂不同浓度、不同扦插基质对插穗生根率、生根数量、生根鲜重、移栽成活率的影响,并监测扦插池空气温湿度。结果表明,三角梅‘绿叶大红’的木质化枝条扦插,以河沙为扦插基质、100 mg/L 双吉尔生根粉(GGR-6)与750 mg/L 吲哚丁酸(IBA)混合液浸泡15 min,扦插池气温在25~40℃,前期湿度在97%以上时,平均生根数量可达107条,生根率可达98%,移栽成活率达96%。生根率与后期种苗移栽成活率不相关,生根数量、生根鲜重与种苗移栽成活率极显著相关,可作为扦插生根效果的衡量指标。三角梅木质化枝条、老粗枝的扦插温度可提高到40℃。

Abstract: To improve new root quality of lignified cuttage of bougainvillea glabra, culture strong seedling, and discover suitable cuttage method, the effects of different rooting agent, dosage, substrate on rooting rate, number, weight, and survival rate of transplantation were surveyed. At the same time, air temperature and humidity were monitored. The results showed following rules. When woody branch was immersed into mixture of 100 mg/L GGR-6 and 750 mg/L IBA for 15 minutes, and cultured in sand with conditions of 25-40℃ air temperature and 97% humidity in early growth period. Average rooting number, rate and survival rate of transplantation of cuttage reached 107, 98% and 96% respectively. Rooting rate dose not related with survival rate of transplantation. As evaluation indexes of rooting effect of cuttage seedling, root number, weight extremely significantly related with survival rate of transplantation.
