植物生长调节剂对壶瓶枣裂果和品质的影响简

以三年生壶瓶枣为试材，以喷等量清水作对照，研究了GA310mg/L＋6-BA10mgL植物生长调节荆混合液定期喷施1次、2次、3次对枣裂果和品质的影响。结果表明：植物生长调节剂处理均未能降低枣裂果率：喷施3次处理均显著增大了果实纵径且极显著增大果实横径；3种处理对枣果实可溶性糖、Vc含量及K、Ca、Mg、Fe元素含量均没有显著影响，喷施1次、喷施2次处理分别极显著地提高了枣果实中Mn、Zn元素的含量。

Effect of Plant Growth Regulator on the Cracking Rate and Quality of Huping Jujube Fruit

In order to investigate the effect of plant growth regulator（PGR）treatments ,including GA310 mg/L and 6-Benzylaminopurine 10 mg/L, spraying once,twice, three times regularly, compared with water treatment on cracking rate and quality of jujube fruit,the 3 years old Huping jujube as the test materials was selected.The results showed that the effect of growth regulator treatment on fruit cracking rate of jujube were not significant. Among the plant growth regulator treatments, three times treatment increased significantly the longitudinal diameter and increased very significantly the transverse diameter of jujube fruit compared with water treatment.The plant growth regulator treatments had no significant impact on the content of soluble sugar, vitamin C, and mineral elements （K, Ca, Mg, Fe ）.Only the once and twice treatment could extremely significantly increase the content of Mn ,Zn eletment in jujube furit than water treatment respectively.
