特晚熟龙眼新株系“立冬本”的研究
Studies on the New Strain of Longan “Lidongben” with Extreme-late Mature Period
-
摘要: 1980年从实生变异中选出的特晚熟龙眼优良单株“立冬本”的研究结果:该优良单株开花结果习性好;丰产;果中大,肉厚,糖高,味浓甜,品质优;制干性能好;成熟期特别迟,比晚熟优良品种“九月乌”迟熟15天,对延长龙眼鲜果供应和加工时间具有特殊意义。无性后代遗传性稳定。过氧化物同工酶酶诺与叶片形态、果实性状相似的“油潭本”不同,是一个新的优良株系。Abstract: A single fine plant of Longan strain "lidongben" was selected from the variation of seedlings in 1980. The investigation results showed that, this single fine strain has good habits in flowering and fruiting, with high yield,middle to large size of fruit body,thick pulp,high sugar content,sweet taste and high quality, easy to be dried. Its maturing period is extremely late, which is 15 days later than the fine strain " Jiuyuewu" (late maturing strain) , so it possesses special significance for prolonging the supply of fresh fruit and processing period. Its asexual descendants have high stability of heredity. The zymographic analysis of peroxidase isozyme showed that, it is different from " Youtanben" which has similarity of leaf-form and fruit shape. "Lidongben" was identified as a new fine strain.
