对梨品种亲缘关系很近的早美酥、中梨1号、七月酥等进行的花粉发芽率、花期调查、自交亲和性、异交亲和性调查的结果表明：三者的花粉在10%的蔗糖液培养基上，24℃左右培养4h后花粉发芽率均能达到60%以上；三者的花期大都集中在4月3日-10日(2003年)；早美酥、中梨1号、七月酥的自花授粉坐果率，除中梨1号的花序自花授粉座果率为48.3%，花朵自交座果率为33.1%外，早美酥、七月酥的花序自交座果率和花朵自自花授粉座果率均达到90%以上；它们的异花授粉坐果率更高，在本试验中花序坐果率和花朵坐果率都可达到94%以上，但最终采果率自花授粉的相对低一些，果实平均种子数也低，异花授粉的最终采果率和果实平均种子数与自然授粉条件下的近似。

Fruit yields, weight of single fruit, per fruit pulp weight, fruit edible ratio, water content of sarcocarp were all increased with the increase of SWC and reached the maximum at SWC75. Soluble brix, soluble suger and titratable acid of fruit had notable or significantly notable negative-linear relations with SWC (R~2 = 0.880 7*; R~2 = 0.717 7* and R~2=0.965 1**) while pH of fruit was increased as SWC did. Brix-acid ratio of fruit was increased linearly with the increase of SWC (R~2=0.908 6*, n=50) and reached the maximum at SWC75. Suger-acid ratio also increased with SWC.

在SWC≤75%时，柑橘产量，单果重，单果果肉重、果实可食率、果肉含水量等随SWC增加而显著增加，在75%时各指标值最高；果实可溶性固形物、可溶性糖和可滴定酸含量分别与SWC呈显著或极显著线性负相关，相关系数分别为R~2=0.880 7~*(n：50)、R~2=0.717 7~*(n=50)和R~2=0.965 1~n=50果实pH值则呈相反趋势，柑橘果实固酸比和糖酸比随SWC的增加而显著增加，果实固酸比与SWC呈显著线性相关(R~2=0.908 6~*，n=50，糖酸比在SWC=75%时达到最大值。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究

Aphids in the process of inhaling plant sap virus particles and auxiliary proteins also be inhaled, thus completing the process by poison, which also supports the field citrus aphid is non-persistent decline disease vector of disease, while the citrus Huanglongbing is phloem restricted by the bacteria caused the main pathogens present in the phloem, the fleas only by phloem feeding in diseased plants, pathogens in the body through the back to complete the salivary glands in the course of the next through the sieve tube feeding in the secretion of saliva the pathogens into the healthy tree, Citrus Huanglongbing different characteristics with aphid-borne diseases, Huanglongbing to persistent disease.

蚜虫在吸入植物汁液的过程中病毒粒子和辅蛋白同时也被吸入，从而完成获毒过程，这也支持了田间蚜虫是柑桔衰退病等非持久性病害传播介体，而柑桔黄龙病是由韧皮部限制性细菌类引起，病原体主要存在于韧皮部中，木虱只有通过在病株韧皮部取食，病原在体内完成循回到唾液腺中，在下一次取食过程中通过在筛管中分泌的唾液将病原体带到健树，柑桔黄龙病与蚜虫传病特点不同，黄龙病为持久性病害。
