Evaluation on Fruit Characters of Helicia nilagirica Bedd from Two Geographical Provenance and Relatives Grafting Compatibility
摘要
Abstract
To understand the fruit traits and pattern of Helicia nilagirica Bedd.from two geographical provenance,ZhenYuan (ZY) and Mo Jiang (M J),we analyzed a number of fruit appearance and quantitative characters.Meanwhile,grafting experiments were made with H.nilagirica seedlings as the stock and three varieties of Macadamia ternifolia F.budling as the scion to preliminarily explore their graft compatibility.The results showed that most fruits were green in color,both for ZY and MJ H.nilagirica.The pericarp of ZY H.nilagirica was mostly smooth,while the pericarp of MJ H.nilagirica was overall rough.The seedling germination rate between the two provenances (ZY 75.39％ and MJ 83.26％) was similar,but in other quantitative characters MJ H.nilagirica was significantly higher than ZhenYuan H.nilagirica.Among the 8 quantitative characters,the cumulative contribution rate of single fruit weight and fruit shape index reached 79.47％ and 96.23％ respectively.Putting the indices into the comprehensive evaluation model,from 72 plant samples,15 plant samples with excellent fruit comprehensive characters were selected,which could be considered to be used in the development and utilization of germplasm resources.The grafting experiment showed the H.nilagirica seedlings were incompatible with Macadamia ternifolia F.bud.关键词
