ClO2对猕猴桃表面溃疡病病菌的杀菌作用及果实货架期品质的影响
猕猴桃 丁香假单胞菌猕猴桃致病性变种 二氧化氯
2020/3/20
为杀灭猕猴桃果实表面溃疡病病原菌并保持果实货架期品质,以丁香假单孢杆菌猕猴桃致病变种(Psa)和海沃德猕猴桃果实为试验材料,通过单因素和响应曲面分析法研究二氧化氯(ClO2)对Psa的杀灭效果及对猕猴桃果实货架期品质的影响。结果表明,最佳杀菌工艺条件为ClO2溶液浓度115 mg·L-1、处理时间8 min、pH值4,在此最佳工艺条件下,ClO2溶液对Psa的杀菌率的最大预期值可达100%,对猕猴...
不同砧木对长富2号幼树生长及果实品质的影响
矮化砧木 长富2号 生长 果实品质
2017/11/23
为明确不同基砧、中间砧对长富2号幼树生长、结果习性的影响,确定晋中地区适宜的砧穗组合,本试验对Y系、SH系、M26矮化中间砧幼树进行连续观察,结果表明,不同基砧对树体生长量、早花习性的影响较小,矮化中间砧对长富2号矮化、早果、提高果实品质的效果明显,不同矮化中间砧致矮、早花效果依次为Y-2>Y-1>SH1>M26>Y-3,其中,Y-1、Y-2矮化中间砧早果性状明显,且能够有效解决长富2号的大小年现...
‘华优’猕猴桃（Actinidia chinensis‘Huayou’）果实采收后用5 mmol · L-1草酸浸泡10 min，置于（0 ± 0.5）℃，RH 90% ~ 95%的冷库贮藏90 d。结果发现，草酸处理能够缓解猕猴桃果实的冷害和细胞膜损伤，延缓硬度、可滴定酸的下降，显著提高超氧化物歧化酶（SOD）和过氧化氢酶（CAT）活性，维持较高的抗坏血酸（AsA）及谷胱甘肽（GSH）含量，降低...
采用硅胶干燥的方法对‘皖杂一号’和‘丰收2号’西瓜品种的种子进行超干贮藏试验，几种不同干燥水平处理的种子在室温条件下历经了23年的密闭贮藏，种子含水量分别降至2.32%和2.23%时，发芽率分别为96%和91%。种子发芽率的高低与其含水量呈显著负相关；过氧化物酶（POD）活性、干种子种胚蔗糖含量与发芽率的变化呈正相关，而超氧化物歧化酶（SOD）活性与发芽率的变化呈负相关。比较‘皖杂一号’超干贮藏9...
