摘　　要：以两个枣品种为试材，研究了花期喷施生长调节剂和氨基酸肥对自花授粉和自然授粉条件下的结实及种仁发育的影响。结果表明，低浓度的GA3（5-10mg／L））虽可提高枣树的结实率但降低了枣果的可育率，当GA3浓度达到35mg／L时结实率亦降低；150mg／L的6-BA、0．02g／L氨基酸肥对自花结实率、自然结实率、自然可育率都有降低作用。The fruit and seed development of two strains of Ziziphus jujuba Mill. ev. Jinsixiaozao, Xiaozao 15 and Xiaozao 24, sprayed with growth regulators and amino acid fertilizers during flowering season, was investigated. The results showed that low concentration of GA3 （5- 10 mg/L） could enhance the percentage of fruits to bearing shoots （PFTBS） and decrease the percentage of fruit with seeds（PFWS） ; However, the PFTBS decreased when GA3 concentration reached 35 mg/L; at 150 mg/L 6 - BA and 0.02 g/L amino acid fertilizers could decrease both PFTBS and PFWS after natural and self- pollination.
