苹果

In this paper, four cultivars of apple were used to study the effects of pectinase addition on methanol and ethanol content during cider fermentation.

以4个苹果品种为研究对象，研究果胶酶(Rapidase ADEX-D)在苹果发酵过程中对甲醇、乙醇含量的影响。

M treatment materials, and also tartaric acid and no maleic acid detected in G. v treatment materials. Inoculation also increased the content of organic acid secretion (increased by 19.80～56.87 mg/kg) of trifoliate root, and the application of AlPO4 greatly increased organic acid content (increased by 20.06～21.84 mg/kg); uninoculated plant root secreted a bit of organic acid; Mycorrhizal poncirus trifoliata seedlings excreted malic acid (42.87%), citric acid (39.22%) and oxalic acid (12.06%).

接种AM真菌的根系分泌的有机酸种类与对照有所不同，未接种处理枳分泌的有机酸有草酸、苹果酸、乳酸、乙酸、顺丁烯二酸和柠檬酸等6种，而接种G.m的则检测到草酸、酒石酸、苹果酸、乳酸、乙酸、柠檬酸、丁二酸等7种，G.v处理的检测到酒石酸，接种处理均未检测到顺丁烯二酸；接种丛枝菌根真菌增加了枳根系分泌有机酸的量比未接种处理增加19.80～56.87 mg/kg，且施用AlPO4后有机酸含量显著增加(增加20.06～21.84 mg/kg；未接种植株根系仅分泌少量有机酸；接种植株根系分泌的有机酸以苹果酸(42.87%)、柠檬酸(39.22%)和草酸(12.06%)为主。

Taking the agroforestry modes of Apple+maize,Apple+Mung bean, Walnut+maize and Walnut+Mung bean in western Shanxi province in loess area as subject,the net photosynthetic rate,transpiration rat,water use efficiency and environmental factors of the same crop or fruit in the four were measured with a portable steady porometer(Li-6400) to study their difference and relationship.

以晋西黄土区苹果+玉米、苹果+绿豆、核桃+玉米、核桃+绿豆4种果树—农作物复合模式为研究对象，分析与不同农作物复合的相同果树的光合速率、蒸腾速率、水分利用效率的差异和原因，果树对农作物的遮荫影响，以及净光合速率、蒸腾速率与环境因子的关系。

In order to understand the relationship between endogenous phytohormones and preharvest fruit drop of apples, contents of IAA and ABA in peduncle, bourse and the tissues around abscission zone of several apple cultivars were periodically analyzed during 8 weeks before harvest, and activity of cellulase in the tissues around abscission zone were periodically analyzed during 20 days before harvest, and ethylene evolution in fruit were analyzed in harvest time.

为了探讨苹果采前落果与内源激素之间的关系，在采前8周间定期测定了不同苹果品种的果柄、果台和离层形成部位组织中IAA、ABA含量；在采收前20d内定期测定了离层部位组织中细胞壁分解酶的活性；在收获期测定了果实乙烯的发生量。

There existed very significant negative correlations among the microenvironment air temperature,surface temperature and the content protopectin and Ca in different periods and times,and very significant positive correlations between the humidity and the content of protopectin and Ca.

微域环境温度、果面温度的年变化和日变化同苹果果皮的果胶含量、Ca含量呈极显著的负相关，湿度同苹果果皮的果胶含量、Ca含量呈极显著的正相关。

The diurnal and seasonal changes of photosynthetic rate of Pyrus bretschneideri (CV.jinfeng and pingguoli) that are cultivated in sandy land were studied.

通过对沙地栽培的苹果梨和锦丰梨2种梨树光合速率日变化、季节变化的测试研究表明：苹果梨Pn日变化呈单峰曲线，峰值出现在上午9：00为10.158 μmol.

In skins, the content of malic acid was far higher than quinicacid, but in seeds it was slightly lower than quinic acid.

果皮中苹果酸含量远高于奎尼酸，但种子中苹果酸含量比奎尼酸稍低。

The main organic acid was citric acid, followed by malic acid. Citric acid and tartaric acid levels increased during storage. Malic acid and quinic acid increased from stage one to stage two. Shikimic acid level increased from stage one to stage three, then decreased slightly. Acetic acid changed unremarkably. Succinic acid changed not significantly from stage one to stage two, then increased and it was the highest in the stage three. The level in stage four and stage five was lower than the level in stage three.

五九香梨果实中的主要有机酸是苹果酸和柠檬酸，整个贮藏期间，柠檬酸和酒石酸含量处于上升趋势，苹果酸和奎宁酸含量在第一、二月贮藏期间增加，而后开始下降；莽草酸含量在贮藏期第一到第三阶段上升，而后略下降；琥珀酸含量在第一到第二阶段变化不明显，接着有上升的趋势，在第三阶段含量达到最高，第四和第五阶段略低于第三阶段；乙酸含量变化不明显。

There are some apple on the tree,and all of the apples are rad.

树上有些苹果，所有的苹果都红了。

Cider, after all, tastes recognizably of apples, so why shouldn't wine taste of grapes?

鉴于苹果酒可以识别出苹果的味道，为什么葡萄酒的味道就不像葡萄呢？

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
