| 中文摘要: |
| 本文对通过人工杂交培育而成的龙眼新品种东良龙眼的果实生长发育特性和果实经济性状进行了分析，并与珠三角主栽培优质品种石硖龙眼（也为其父本）进行了对比。结果表明，在果实发育早期主要是果皮和种子的发育，在花后32天左右开始长出半透明的果肉，15-20天后包满种子。花后84天左右果肉开始快速生长，可溶性固形物含量快速增加。东良龙眼在果实近成熟时全果和果肉的重量还在快速增长。果大、可食率高、味甜、肉质爽脆，品质上等，可与优质品种石硖龙眼相媲美，是一个值得大力推广的龙眼优良新品种。 |

| The fruit development and characteristics were analysed of Dongliang logan, a new longan cultivar bred by artifical hybridization.The results showed that:in the early development stage, pericarp and seed developed mainly. 32 days after flower, the translucent flesh appeared, and packaged the seed 15-20 days late. 84 days after flower, the flesh and content of TSS grew rapidly. Approaching maturity, the fruit and the flesh continued growing rapidly. Compared with its male parent Shixia longan, a high quality main cultivar in the pearl river delta region, Dongliang longan’s fruit was bigger, and its edible rate was higher. It was very sweet, crisp and tasty as Shixia longan. Many fruit economic characteristics of Dongliang longon rival Shixia longon. It is a high quality cultivar and has a broad prospect for promotion. |
