The rind of muskmelon (Cucumis melo L. var. reticulatus) fruits contains a network of suberized periderm tissue, referred as the ‘net’, which originates in response to cracking of the fruit surface during its enlargement. Shallow cuts were made on the surface of melons to mimic naturally occurring cracking and induce net-like periderm development. Histological analysis of wounded fruits of the climacteric netted variety Krimka, and of two smooth melon varieties: the climacteric Momordica and the non-climacteric Tamdew, indicated that smooth melon varieties can undergo netting when their rind is fissured. Furthermore, the results implied that the climacteric character is not essential for net-tissue development, even though most netted varieties are climacteric. The involvement of ethylene in net-like periderm development was studied by analyzing the expression pattern of the ethylene-biosynthesis genes 1-aminocyclopropane-1-carboxylate synthase 1 and 1-aminocyclopropane-1-carboxylate oxidase 1 following wounding and during periderm development, and by applying the ethylene-generating chemical, Ethrel, as a lanolin paste, on the fresh cuts. Results suggested ethylene involvement in periderm initiation, but continuous exposure may interfere with further tissue development and organization. General implications of the current study on periderm development are further discussed. 相似文献

来自甜瓜属( Cucumis melo L. ) 6 个变种部分品种货架期差异比较 总被引:1,自引:0,他引:1
对甜瓜属6 个变种的13 个材料的货架期及相关因素进行了测定比较。结果表明, 来自var.saccharinus 和inodorus 的5 个品系表现出乙烯释放速率和鲜样质量损失率很低, 货架期显著优于其它变种的材料。var. reticulatus 虽然乙烯释放量较低, 但由于果肉软化, 其货架期短于var. inodorus 。var. cantalupensis , makuwa 和acidulus 货架期短。相关性分析显示货架期还与果实发育期及果实质量存在高度相关, 而果实表面的网纹结构与乙烯释放速率、鲜样质量损失速率及货架期并无显著的相关性。 相似文献

通过植株生育期、田间主要性状、果实外观和内质等性状的比较,筛选出适合桂北生态区设施栽培的优质厚皮甜瓜品种,2010年对13个厚皮甜瓜引进品种进行品比试验,结果表明,翠甜、天仙2个品种综合性状较好,果实外观与果肉品质口感俱佳,抗病性强,适合在桂北生态区推广种植;橙露可作为晚熟品种于夏秋茬采用嫁接苗、无土基质方式栽培;京玉5号、白流星、京玉月亮品质较好,外观美丽,可作为高档礼品甜瓜、观光采摘及个性化栽培;天蜜肉质特别柔软,不适合桂北地区大多数消费者的口感习惯,建议根据不同销售市场需要有选择栽培。其余品种含糖量较低、口感偏淡,不太适合桂北生态区栽培。 相似文献

Oxygen deficiency has an immediate effect on both water and nutrient uptake, the yield of the whole plant under different soilless culture is affected. The oxygen level required for the respiration of the root system then becomes a limiting factor as much in soil culture as in soilless culture. The total area of soilless crops in SE Spain today is estimated to be about 5000 ha. The objective of this experiment was to study the effect of potassium peroxide as an oxygen generator on vegetable crops growing in commercial substrates and to determinate the supply fraction for its use. Bioassay was used to determinate the fraction of potassium peroxide needed. Three greenhouse experiments were conducted in soilless culture with perlite and rockwool. Sweet pepper, melon and cucumber crop were supplied with potassium peroxide through fertigation to increase the oxygen content for one day per week. There were treatments: one with (T1) and the other without potassium peroxide (T0) in the nutrient solution. Fertigation parameters, yield and its quality were measured. Bioassay suggested that one gram per litre is the best fraction to use in soilless culture. Yield of sweet pepper was about 20% higher for T1 than T0 and 15% for melon; there was no significant difference in cucumber plants. 相似文献

厚皮甜瓜四倍体的诱导及其特性变化 总被引:1,自引:0,他引:1
以3份二倍体厚皮甜瓜为试材,采用0.2%秋水仙碱处理去掉生长点的幼苗茎尖,研究剥滴法对四倍体诱导率的影响以及四倍体甜瓜特征特性的变化。结果表明:网纹型材料M066的四倍体诱导率达54.4%,光皮型材料M072和M0544四倍体诱导率分别为20.0%和23.3%。与二倍体甜瓜相比,四倍体植株侧蔓节间距变短,花冠与叶片变大,保卫细胞叶绿体数增加,花粉可染率和单瓜种子可育率降低,单果重及果形指数变小,果肉厚度同二倍体,可溶性固形物含量降低。该试验结果说明,不同基因型甜瓜材料诱变率差异显著,四倍体甜瓜生理生态特性变化显著。 相似文献

根据模糊数学的基本原理,测定合肥地区大棚栽培的11个厚、薄皮甜瓜早熟品种类型的成熟期、产量、品质、抗病性等11个经济性状,对分析的品种经济性状表现优劣进行了综合评判。结果表明:‘江淮蜜1号’和‘里外红’的综合经济性状较好;‘黄子金玉’、‘甜美’、‘丰蜜’、‘翠蜜’次之;‘碧玉’、‘网蜜’、‘银蜜’、‘白美丽’、‘青香玉’较差。因此,早熟大棚栽培甜瓜,其生态类型以厚皮甜瓜为首选,如‘江淮蜜1号’、‘里外红’、‘甜美’、‘丰蜜’、‘翠蜜’;其次选用部分厚薄皮杂交型品种,如‘黄子金玉’;同时部分薄皮甜瓜品种如‘白美丽’、‘青香玉’抗逆性较好,坐果节位较低,建议在合肥地区3月底至4月初露地栽培为宜。 相似文献
