施硼和赤霉素对澳洲坚果产量及果实品质的影响OA

Effects of Boron and Gibberellin Spraying on Yield and Fruit Quality of Macadamia

中文摘要英文摘要

以澳洲坚果品种'HASE695'为试材,研究喷施硼和赤霉素对植株产量及果实品质的影响,为澳洲坚果提质增效栽培技术提供理论依据.通过田间小区试验,测定T1(100 mg/L赤霉素)、T2(0.3%硼)和T3(100 mg/L赤霉素+0.3%硼)处理的植株落果率、单株产量、果实外观品质(鲜果单果重、壳果单果重、壳果纵径、壳果横径、果形指数、出种率、出仁率)和营养品质(粗脂肪、蛋白质、总糖、氨基酸)指标.结果表明,与对照组相比,T1和T2处理单株产量显著提高;T3处理落果率显著降低,单株产量显著提高,果仁中蛋白质、总糖、氨基酸含量显著或极显著增加.研究发现,100 mg/L赤霉素+0.3%硼复配施用效果最佳,可显著提高澳洲坚果的产量和改善果实品质.

The effects of boron and gibberellin spraying on yield and fruit quality of macadamia variety'HASE695'were studied to provide theoretical basis for quality and efficiency improving cultivation techniques.Field plot experiment was conducted to determine the fruit abscission rate,yield per plant,fruit appearance quality(single fresh fruit weight,single shell fruit weight,shell fruit longitudinal diameter,shell fruit transverse diameter,fruit shape index,seed percentage,kernel percentage)and nutritional quality(crude fat,protein,total sugar,amino acid)under 100mg/L gibberellin(T1),0.3%boron(T2)and 100 mg/L gibberellin combined with 0.3%boron(T3).The results showed that T1 and T2 treatments significantly increased the yield per plant,and T3 treatment significantly reduced the fruit drop rate,extremely significantly increased the yield per plant,significantly or extremely significantly increased the protein,total sugar and amino acid contents in the kernel compared with the control.It was found that 100mg/L gib-berellin combined with 0.3%boron had the best effect,which could significantly improve yield and fruit quality of macadamia.
