早酥梨系早熟梨品种,在辽宁8月中旬成熟。在此之前正值梨短缺的酷暑盛夏,倘能使其再提早10天成熟登市,既可提高其商品价值,调节市场供应,又可拉长成熟期,减轻采收集中所带来的劳力紧张。为此,1981～1982年在所内六、七年生早酥梨上,进行了采前喷布乙烯利催熟试验。试验结果表明:1.采前25天喷布各种浓度(800、300、150、50ppm)的乙烯利均有明显的催熟效果, Morning pear is a pear variety early maturing in mid-August in Liaoning mature. Prior to this, there was a summer of summer when pear shortage was experiencing a 10-day maturity listing ahead of schedule. This will not only increase the value of its commodities and market supply but also prolong the maturity and ease the labor-intensive effects of the intensive harvesting tension. To this end, from 1981 to 1982 in the six or seven years as early as pear on the pre-harvest ethephon ripening test. The test results showed that: 1. 25 days before the injection of various concentrations (800,300,150,50ppm) of ethephon have significant ripening effect,
