3个红梨品种在湖南的引种观察

Introduction performance of three red pear varieties in Hunan

对引入湖南省浏阳的3个红梨品种美人酥、红酥脆与满天红进行了生长结果习性、适应性以及果实品质的观察比较。结果表明,3个红梨品种在浏阳地区均能正常完成年生长周期,美人酥与满天红生长旺,坐果稳,盛果期树666.7 m 2产量1400 kg,红酥脆长势稍弱,产量1200 kg。3个红梨品种着色均不稳定,果皮锈斑较严重,对着色影响大,以满天红着色相对较好,美人酥次之,红酥脆较差。3个红梨品种均在9月中旬前后成熟,单果重300 g以上,肉质细,石细胞少。可溶性固形物含量13.0%~13.8%,可溶性糖含量9.05%~9.36%,均以美人酥含量最高,其次为满天红、红酥脆。总酸含量1.13~1.42 g/kg,以满天红最高,美人酥与红酥脆相近。综合分析认为,3个品种均不适宜在湖南地区大面积发展。

The growth and fruiting habits,adaptability,and fruit quality comparison of three red pear varieties,Meirensu,Hongsucui,and Mantianhong,which introduced into Liuyang area of Hunan province,were observed and compared.The results showed that the three varieties could complete their annual growth cycle normally in Liuyang area,with Meirensu and Mantianhong growing vigorously,stable fruit setting,and yield of 1400 kg per 666.7 m 2.The growth of Hongsucui was slightly weak,with yield of 1200 kg per 666.7 m 2.The coloring of the three varieties was unstable,with severe rust spots on the fruit skin,which had a significant impact on their coloring.The coloring of Mantianhong was relatively better,followed by Meirensu and Hongsucui.All three varieties were mature around mid-September,with the single fruit weight over 300 g,fine flesh,and few stone cells.The soluble solids content was 13.0%~13.8%,and the soluble sugars content was 9.05%~9.36%,all of which were the highest in Meirensu,followed by Mantianhong and Hongsucui.The total acid content was 1.13~1.42 g/kg,with the highest in Mantianhong,and similar in Meirensu and Hongsucui.According to comprehensive analysis,all three varieties are not suitable for large-scale development in Hunan.
