摘要
从石硖系列品种中选出一个芽变特晚熟优良新株系 ,生物学特性与石硖品种有明显差异 ,初步命名为“特晚熟龙眼”。该株系生长旺盛 ,枝梢萌发力强 ,每年抽生新梢 5～ 6次 ;花芽分化期一般在元月下旬至 2月上旬 ,现蕾期在 2月中下旬 ,初花期在 3月下旬至 4月初 ,盛花期在 4月 8～ 15日 ;末花期在 4月 2 0～ 2 5日 ;果实成熟期比目前我区推广的主要迟熟品种晚熟 7～ 10天。果实中等大 ,近圆形 ,平均单果重 12～ 13克 ,肉厚干胞、质脆带滑 ,口感味甜 ,有微香 ,易离核 ,可溶性固形物含量为 19.6%～ 2 1.2 % ,可食部分占 68%～ 72 %。
A new superior longan line that is highly latematuring has been selected from the bud sports of Shixia varieties, which shows significantly different from the mother line in biological characteristics, and was named Highly LateMaturing Longan. The new line grows fast and it has strong ability to generate new branches and shoots, and it produces new shoots for 5 to 6 times each year. Its flower buds are differentiated from late January to early February, and the flower buds can be seen in the mid or late February. It begins to flower between late March and early April, blossoms between April 8 and 15, and ends flowering between April 20 and 25. Its fruit ripening date is generally in mid September, which is 7 to 10 days later than those of the present major cultivars. Its fruits are middle in volume, almost round in shape, and the single fruit weight is 12 to 13 g. The flesh is solid with sweet juice and good taste, and easily removed from the nucleus. The content of soluble solids is 19.6% to 21.2% in the juice. The edible part occupied 68% to 72% of the whole fruit.
