为研究不同保鲜技术对软枣猕猴桃贮藏期间营养成分的影响,该研究采用1.5%壳聚糖活性涂膜（CH）、1.5%壳聚糖柠檬精油复合涂膜（CHO）和1μL·L-11-甲基环丙烯（1-MCP）对软枣猕猴桃进行保鲜处理,测定果实在4℃条件下贮存过程中VC含量、可滴定酸和可溶性固形物含量变化情况。结果表明,3种保鲜处理对维持软枣猕猴桃果实营养品质均具有明显效果。其中CH组和1-MCP组处理的软枣猕猴桃果实VC含量较稳定;1-MCP组处理的可滴定酸含量最好;CHO组处理对于减缓可溶性固形物含量上升速度、延长保鲜时间效果最好。该研究结果旨在为1-MCP和壳聚糖涂膜技术在猕猴桃低温保鲜中的应用提供理论依据。 相似文献

为了探讨软枣猕猴桃[Actinidia arguta(Sieb.et Zucc.)Planch.Ex Miquel]果实软化特性,以软枣猕猴桃果实为试材,测定了果实软化各个阶段的品质、呼吸率、乙烯发生量、淀粉含量、细胞壁成分变化以及果实软化阶段果胶和半纤维素分子大小变化。结果表明,软枣猕猴桃果实软化过程中硬度迅速下降、可溶性固形物含量迅速增加和可滴定酸含量下降明显。在果实软化前期淀粉降解迅速,呼吸高峰出现,乙烯发生量增加,半纤维素降解明显;而果实软化后期果胶和纤维素降解明显。初步认为软枣猕猴桃果实软化是淀粉降解、乙烯和果胶酶等多种因素共同作用的结果。 相似文献

We modeled the effects of weather and source-sink factors on mango fruit growth. The peach fruit-growth model "Cashoo" was adapted for mango fruit. The model accounts for the main processes of fruit growth, i.e., leaf photosynthesis, fruit demand, fruit respiration, and storage and mobilization of leaf and stem reserves. Simulations for three successive years and for various leaf-to-fruit ratio treatments showed good agreement with observed fruit growth data. Simulations of fruit growth under different climatic conditions, especially with contrasting temperature and radiation, and for different values of initial fruit dry mass and leaf-to-fruit ratio, showed that variations in fruit growth among years can be partly explained by climatic variations through their effects on leaf photosynthesis, fruit demand and fruit growth rate. However, climatic changes contribute substantially less to observed variability in fruit growth than to initial fruit dry mass and leaf-to-fruit ratio. 相似文献

植物生长调节剂对油茶果实含油率的影响 总被引：7，自引：2，他引：7
以油茶优良无性系为材料,对其喷施植物生长调节剂,测定油茶果实含油率的变化情况.结果表明:不同生长调节剂对油茶鲜果含油率的影响差异很大,B-9、GA和乙烯利等3种生长调节剂对油茶鲜果含油量的提高有明显的促进作用,比对照增22.4%、16.2%和11.2%,喷施生长调节剂后,还可使油茶鲜果含油量的快速积累提前到9月上旬;叶面喷施GA和B-9可以促进油茶种仁含油量提高42.6%和40.4%,比对照增18.0%和11.9%;喷施稀土和NAA对提高种仁含油率有反作用;油茶鲜果出籽率在8月中旬到10月下旬期间,呈现马鞍形增长的趋势,但喷施生长调节剂对其作用不明显;油茶果实后熟期以不同生长调节剂处理,对茶果出油率和出干籽率提高有促进作用,喷施赤霉素加萘乙酸(GA NAA)和只喷施赤霉素(GA)的处理出油率最高达6.01%和5.95%,分别比对照增22.1%和20.9%. 相似文献

通过对油茶主要良种的标定植株进行果实生长和含油量分析研究,探索油茶果实油脂形成与转化的内在机理.结果表明果实体积生长主要在6月中旬至7月下旬.油茶果实质量的增加主要在6月中旬至7月下旬和9月中旬至10月下旬采收前两个高峰期,其质量增加值超过油茶果实总质量的2/3.油茶种仁含油率、鲜籽含油率和鲜果含油率均随果实生长逐渐增加,年周期内存在两个增长高峰期,为8月中旬至9月初与9月下旬至10月下旬采收前.油茶鲜果含油率在9月20日至10月20日的高峰期的增幅达鲜果总含油量的68.9%,指出霜降籽油茶果实不宜提前采收,否则会对产油量造成很大的损失. 相似文献

Data on the seasonal patterns of fruit growth and dark respiration of two peach (Prunus persica (L.) Batsch) cultivars were combined with temperature data to calculate the carbohydrate requirements of an "average" peach fruit from bloom to harvest. The two peach cultivars used were June Lady (an early maturing (mid-June) cultivar) and O'Henry (a late maturing (early-August) cultivar). At harvest, the mean dry weight of the June Lady fruit was 17.8 g (139.7 g fresh weight) and of O'Henry fruits was 30.9 g (213.9 g fresh weight), and the times from full bloom to harvest were 107 and 154 days, respectively. The total calculated fruit respiration requirements were 132 and 300 mmol CO(2) fruit(-1) season(-1) for June Lady and O'Henry fruits, respectively. Total calculated carbohydrate requirements for fruit growth and respiration are 23.9 and 43.8 g CH(2)O fruit(-1) season(-1) for June Lady and O'Henry fruits, respectively. Fruit respiration accounted for 16.3% of the total carbohydrate requirements of June Lady fruits and 0.5% of the total carbohydrate requirements of O'Henry fruits. 相似文献
