- 摘要:
- ‘蜀都蜜’是由‘金花’ב早酥’杂交选育出的早熟砂梨新品种。该品种树势中庸，树姿半开张；一年生枝条呈黄褐色，皮孔小且分布稀疏；叶片长椭圆形，叶缘锐锯齿；每花序5~9朵花，花药浅粉红色，花柱高于花药，以短果枝结果为主。果实呈纺锤形，果面光洁，黄绿色，果点小；平均单果质量231.5 g；果肉白色，肉质细脆，石细胞少，风味甜蜜浓郁，可溶性固形物含量13.7%，可溶性糖含量8.43%，可滴定酸含量0.22%，果实硬度8.34 kg·cm-2。在成都崇州地区于3月上旬开花，7月上旬果实成熟，果实发育期约115 d；适应性与抗性较好，生物学性状和经济性状稳定，适宜在四川、重庆等平原和丘陵砂梨生态区种植。
- Abstract:
- ‘Shudumi’ is a new early-ripening pear cultivar bred by crossing ‘Jinhua’ × ‘Zaosu’.The species tree posture moderate，tree posture half open.The 1-year-old branches are yellowish brown，with small lenticels and sparse distribution.Leaves long oval，leaf margin acute serrated；each inflorescence 5-9 flowers，anther light pink，style is higher than the anther，with short fruit branch results.Fruit spindle-shaped，smooth surface，yellow-green，small fruit spots；the average fruit weight is 231.5 g.The flesh is white，crisp，less stone cells，sweet and rich in flavor.The soluble solids content (w，the same after) is 13.7%，the soluble sugar content is 8.43%，the titratable acid content is 0.22%，and the fruit hardness is 8.34 kg·cm-2.It blooms in early March and matures in early July in Chongzhou，Chengdu.The fruit development period is about 115 days.Adaptability and resistance is good，biological and economic traits stable，suitable for planting in Sichuan，Chongqing and other plains and hilly pear ecological zone.
