多穗的

Lilhocarpus Polystachys Rehd is a sweet and nonsugar folk drink, which has centuries-old edible history. It can prevent many cardiovascular diseases according to Chinese herbalist.

多穗柯甜茶是一种具有很长食用历史的民间非糖甜味饮品，中医药认为其对多种心血管疾病有预防作用。

In addition, it must seek unisonous combination of effective panicle number and more spikelets per panicle and big grain on the basis of higher effective panicle number.

通过成穗率高的选择，不仅对提高新组合的产量水平具有正效应，而且成穗率可以作为一个核心性状协调多穗与大穗、大粒之间的矛盾，进而实现有效穗数多与大穗、大粒在更高水平上的结合，从而获得更高的产量。

As to Balilla erect panicle type,(the same subject for the following 11-16), the curvature of panicle neck had a very significantly positive correlation with panicle length, neck panicle length, neck panicle internode length, the secondary internode length, leaf length and leaf sheath length, and had an opposite correlation with leaf width and density of seed setting.

来自吉林的直立穗型品系Z1和来自黑龙江的直立穗型品种龙交91060—2与巴利拉型直立穗型品种的直立穗其因分属于3个不同的位点，各自位于3对同源染色体上，彼此遵循基因的自由重组和独立分配规律。Z1由1对显性主效核基因控制，龙交91061—2由1对隐性主效核基因控制。3个直立穗型基因位点可能具有累加效应，直立穗型效应位点越多，则颈穗弯曲度越小，穗的直立性越强。

Softwood cuttings of Codiaeum variegatum var.pictum were treated with diffrent concentrations of solutions 1 (1％Triadimefon +15％Ethylicin WP) and 2 (15％Carbendazim + 15％Thiram WP)for 3 hours.

以琴叶变叶木（Codiaeum variegatum var 。pictum）为材料，用1%三唑酮+15%乙蒜素可湿性粉剂和15%多菌灵+15%福美双可湿性粉剂分别配制成不同浓度的系列溶液，对插穗浸泡处理3 h后扦插试验，研究这两种混合杀菌剂对插穗的影响。

本研究首先研发出一套简单、有效的制备性提取分离多穗柯黄酮类及其根皮苷工艺，这套工艺包括：(1)微波辅助氢氧化钙水溶液提取多穗柯黄酮，最佳工艺条件为用1.2 %氢氧化钙水溶液为提取液，料液比1：12，预煮时间5min，微波功率800W处理25min。

ObjectiveTo solve the infection of asymmetric absorption peak in determination of flavonoids in lithocarpus polysachyus rehd leaves.

黄酮类化合物；，，多穗柯；，，三波长分光光度法摘要：目的清除由于多穗柯叶中黄酮光谱吸收峰不对称给定量分析造成的影响。

First, this research developed a set of simple and effective technologies for preparative extraction and separation of flavonoid and phloridzin from Lithocarpus polystachyus, which includes:(1) Microwave-assisted extraction of flavonoid from tender leaves of Lithocarpus polystachyus Rehd. The extraction conditions are as the follows, 1.2 % of Ca2 water solution, solid-liquid ratio of 1:12, pre-boiling for 5 min, 800 W of microwave treating for 25 min.

本研究首先研发出一套简单、有效的制备性提取分离多穗柯黄酮类及其根皮苷工艺，这套工艺包括：(1)微波辅助氢氧化钙水溶液提取多穗柯黄酮，最佳工艺条件为用1.2 %氢氧化钙水溶液为提取液，料液比1：12，预煮时间5min，微波功率800W处理25min。

Using design of L9 (3^4), the extraction conditions of total flavonoids from Lithocarpus polystachyus Rehd. in Huaihua were optimized by ethanol solution extraction assisted with ultrasonic, and the variety trends of total flavonoids content were investigated with different natural storage time, different gathering seasons, differrent Lithocarpus polystachyus Rehd.

以怀化产多穗柯为原料，采取乙醇为溶剂超声波辅助提取，以L9(3^4)正交试验方法优化总黄酮提取工艺，然后在该工艺条件下对自然存放时间不同、采摘季节不同、不同叶的多穗柯原料进行总黄酮含量的动态变化考察。

Leaves. Result: Extraction temperature had effect on total flavonoids yield, and ethanol concentration had more obvious effect than extraction temperature. The more natural storage time, the less total flavonoids content, and the average descent rate was 24.74% per year. The flavonoids content from Lithocarpus polystachyus Rehd. gathered between August and October was the highest. The total flavonoids content was higher in the new leaves of Lithocarpus polystachyus Rehd.

结果：乙醇体积分数对总黄酮提取量有显著影响，提取温度对总黄酮提取量有影响；多穗柯自然存放时间越长，总黄酮含量越低，平均每年下降24.74%；不同季节采摘的多穗柯其总黄酮含量以8~10月最高；经对怀化多穗柯嫩叶和老叶中总黄酮的提取测定表明，多穗柯中嫩叶总黄酮含量最高，二年生最低。

Polygynous flowers were located in the middle of panicles, while there were no polygynous ones on the top and the base of panicles.

多子房小花一般位于穗的中部，而顶部和基部小花未发现多子房现象。
