据《Hort Science》(2012年11月)的一篇研究报道,来自美国北卡罗来纳州立大学园艺科学系的研究人员研究了1-氨基环丙烷羧酸和苯嗪草酮对苹果后期疏果的效果。使用化学疏果剂疏果一般是在苹果开花期至花期3周、果实直径约16mm时进行,这段时期之后果实一般对常规化学疏果剂不敏感。研究人员研究了在传统疏果期后使用光合系统II(PSII)抑制剂苯嗪草酮和乙烯前体1-氨基环丙烷羧酸(ACC)的疏果效果。连续3年进行田间试验,于2010、2011和2012年果实平均直径分别为18、20和27mm时喷洒西维因、乙烯利和萘乙酸(NAA)的标准稀释液降低了 According to a study by Hort Science (November 2012), researchers from the Department of Horticulture, North Carolina State University, studied the effect of 1-aminocyclopropanecarboxylic acid and trimethoprim on apple thinning later in life . The use of chelating agent thinning fruit is generally in apple flowering to flowering 3 weeks, when the fruit diameter of about 16mm, after this period the fruit is generally insensitive to conventional chelating agents. The researchers studied the fruit-thinning effect of metribuzin and the ethylene precursor 1-aminocyclopropanecarboxylic acid (ACC) using the photosystem II (PSII) inhibitor after the traditional thinning period. Field trials were conducted for 3 years in succession with the application of cinebulin at 18, 20 and 27 mm fruit average diameters in 2010, 2011 and 2012, respectively, and the standard dilutions of ethephon and NAA were reduced
