在2005年和2006年生长季节期间在约旦Ajloun的Ras Munif（32度22 'N，35度45' E）进行了田间试验，以评估不同的授粉处理及其对地中海条件下生长的枇杷果实的坐果和品质的影响。开放，补充，雨水，和覆盖授粉处理施加在选定的树木。结果表明，与雨水和覆盖处理相比，补充授粉和自由授粉的坐果率极高。尽管作物负荷很重，但在开放授粉和补充授粉下获得的果实也更重更大，这可能部分是由于种子和果肉重量显著增加。糖含量对自由授粉和补充授粉都有好处。风在枇杷授粉过程中几乎没有作用。枇杷花吸引的蜜蜂数量非常有限，A。蜜蜂科的意大利蜂、白腹蜂、紫腹木蜂和石蟹科的四带石蟹是枇杷唯一的访花蜂。它们的访问时间有所不同，但枇杷花在中午吸引率和数量最高。(c)2008 Elsevier B.V.保留所有权利。
A field experiment was conducted during 2005 and 2006 growing seasons at Ras Munif (32 degrees 22'N, 35 degrees 45'E), Ajloun, Jordan, to evaluate different pollination treatments and their effects on fruit set and quality of loquat fruit grown under Mediterranean conditions. Open, supplemental, rain, and covered pollination treatments were imposed on the selected trees. Results showed that under supplemental and open-pollination, extremely higher fruit set was obtained compared with rain and covered treatments. In spite of a heavy crop load, fruits obtained under open and supplemental pollination were also heavier and larger, this could be partly due to a significant increase in seeds and flesh weight. Sugar content was good for both open and supplemental pollination. Wind plays little or no role in loquat pollination process. Loquat flowers attracted very limited number of bee visitors, A. mellifera, Anthophora albigena and Xylocopa violocea of family Apidae and Halictus quadricinctus of family Halictidae were recorded the only loquat flower visitors. They showed a variation in their visiting time but loquat flowers attracted the highest rate and number during the mid of the day. (c) 2008 Elsevier B.V. All rights reserved.
