常山胡柚应用ABT-9生根粉进行保花保果试验初报

Preliminary Report on Application of ABT-9 Rooting Powder to Retain Flower and Fruit of Changshan Shaddock

结果表明，B及B+Ca处理明显降低胡柚果实的IAA、GA3、ABA的含量及果实发育前期的ABA/（IAA+GA3）比率，降低了IAA氧化酶的活性，提高了过氧化物酶（POD）的活性；

The results showed that B and B + Ca treatments significantly decreased the content of IAA , GA3 , ABA and ratio of ABA / ( IAA + GA3 ) in the fruit early development stage . They decreased IAA oxidase activity and increased POD activity .

分别发酵生产胡柚果醋，对其进行感官分析，以Vitek-32型微生物分析系统对最适菌种进行鉴定。

Meanwhile , the sensory evaluation of vinegar fermented by these strains was carried out and the optimal strain screened was identified using VITEK-32 automatic microorganism analysis system .

叶面喷硼对胡柚和温州蜜柑生理特性的影响

Effects of boron on physiological characteristic of two citrus species

以常山胡柚鲜果为原料，采用不同处理来加工研制常山胡柚果酱制品。

Changshan-huyou jam was processed by using changshan-huyou fresh fruit as the raw material and adopting different treatments .

授以胡柚混合花粉的果实中，7.2%没有种子，自花授粉的果实全部没有种子。

Self-pollinated progeny had no seed , fruit pollinated with Citrus grandis among which 7.2 % had no seed .

根据胡柚生长发育与气象条件的关系，确定了胡柚种植的农业气候区划指标。

The agricultural climate pision index is studied and defined according to the relationship between Huyou production and meteorological conditions .

国外至今尚无此种，也没有这方面的研究报道，所以对常山胡柚开展系列研究，还具有十分重要的学术价值。

There is no report on such researches abroad , so these series of researches will even be of very important academic value .

玉环柚、常山胡柚、黄岩柑桔等分布在沿海平原及山间盆地，地势较低的地方；

Yuhuan pomelo , Changshan Hu pomelo , Huangyan honey tangerine are distributed in low-lying area such as coastal plains and intermontane basins .

方法：采用硅胶柱色谱分离及重结晶的方法从胡柚皮中分离化合物，并根据理化性质和波谱数据进行化合物的结构鉴定。

Methods : Various chromatographic techniques were used to isolate and purify the constituents , their physical-chemical properties and spectral data determined to elucidate the structures .

提出今后在常山胡柚的分子鉴定、果实的生长发育规律与成熟机理、果实的贮藏保鲜、深加工及综合利用等方面需深入研究，以真正提高常山胡柚的产量和品质。

Future research orientations should include such programs as molecular characterization , fruit growth pattern , maturity mechanism , freshness retention , deep-processing and comprehensive utilization .

花芽分化和物候期存在一定的相关性.刚进入盛果期的胡柚，其春梢结果母枝的各节位均能分化花芽，主要集中在其顶端的第1￣第4节位上。

During full fruit period , each node of fruit bearing branch had bud flower differentiation , mainly concentrated from first to forth node of branch tip .

胡柚皮中黄酮类化合物最佳提取条件为乙醇浓度90%，料：液比1：5，提取时间115min，提取温度20℃，最大提取量为1.98g/L；

Among them extracting time was the primary condition . The best extracting conditions were 90 % alcohol content , the ratio of material to solvent 1:5 , 115 minutes and 20 ℃ .
