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.

对巴利拉型直立穗型品种来说（以下11～16同此所指），颈穗弯曲度与穗长、穗颈长、穗颈节间长、倒2节间长、叶长、叶鞘长呈极显著正相关（倒3叶呈显著正相关），与叶宽、着粒密度呈极显著负相关。

Sorghum, sudenese grass and orchard-grass (Dactylis glomerata L.), and the application of MeJA for the flowering synchronization of male sterile and restorer lines was investigated in seed production of hybrid rice.

外源MeJA强烈诱导稻、高粱、苏丹草和果园草等禾本科植物的颖花开放：早稻297的离体穗在经40μmol/L，400μmol/L和4mmol/L的MeJA溶液浸穗 2min处理后80min，在对照颖花开放尚未启动时，平均每穗颖花开放率分别达 7.5％，22.7％和44.5％；杂交稻安湘S-株173的连穗经4mmol/L的MeJA溶液浸穗2min处理后80min，开颖率达32.5％；不育系也能响应MeJA的诱导，经1mmol/L MeJA处理后，80min时开颖率达42.9±6.1％。

Effect of exogenous plant growth substance on the preharvest sprouting formation, endogenous phytohormones and related physiological and biochemical characteristic and agronomic properties were studied by spraying the exogenous GA3 and ABA on rice on the seventh day after tasseling, the results are as follows:Rice variety with high germinating potential is easier for preharvest sprouting.

穗上芽发生难易除种子自身遗传因子的影响之外，还与水稻种子自身内源激素GA_3和ABA含量密切相关，尤其与GA_3/ABA比值有关，易穗上发芽品种GA_3/ABA比值相对较高。研究表明，易穗上发芽水稻品种在穗萌到穗芽过程中α-淀粉酶活性、可溶性糖含量、可溶性蛋白和种子中含水量比不易穗上发芽的品种均相对较高。

The new shredding mechanism is in installs a cylinder knife under the horizontal-type stripper roller, there is a cut knife at the front of the cylinder knife, after the corn stem enters the gap between stripper roller, is cut off by the knife .When the stripper roller is working, it picking the corn cob, at the same time it take the corn stem into the cylinder knife, the corn stem is cut off by the knife, then the corn stem that has been cut off is thrown out by the cylinder knife.

新装置基于背负式穗茎兼收玉米联合收获机设计，原理是在每对卧式摘穗辊的下方安装一个滚筒刀，在滚筒刀的前端安装有割断刀，当玉米茎杆进入摘穗辊间隙后被割断刀打断，摘穗辊进行摘穗工作的同时将已被打断的玉米茎杆喂入到滚筒刀中切碎，切碎后的茎杆被滚筒刀抛送到茎杆收集装置中。

The physiology characters of the leaf of ear in different periods have been studied It is showed that the water content and protein content,leaf_area and protein weight per square of leaf of ear from silking to 42d after silking all reduce gradually , but dry-weight and leaf -area did not do The correlate analysis showed that the protein content of leaf of ear in different periods and protein- weight per square did not correlate significantly with protein content of seed Dry weight of leaf of ear was ...

研究不同时期穗位叶的部分生理性状表明：从吐丝期至其后 4 2d ，穗位叶的含水量、单位叶面积、蛋白质含量和单位叶面积蛋白质重量均呈现一个逐渐下降的趋势；穗位叶叶片干重和叶面积基本保持不变。相关分析表明，不同时期穗位叶的蛋白质含量、单位叶面积蛋白质重量与子粒蛋白质含量无关，而吐丝期穗位叶干重和子粒蛋白质含量呈显著正相关

Based on above classification, resistant scale of the rice cultivars against false smut asthe field evaluation may be divided into 6 scales, viz. 0: 0.00～0.09disease grains ofthe average each panicle; 1: 0.01～0.30; 3:0.31～0.40; 5: 0.41～0.50;7:0.51～1.10; 9:＞1.10.

以以上分类为依据，将水稻抗稻曲病的田间抗性相应地划分为6级：0级：平均每穗病粒数为0.00～0.09；1级：平均每穗病粒数0.10～0.30；3级：平均每穗病粒数0.31～0.40；5级：平均每穗病粒数0.41-0.5；7级：平均每穗病粒数0.51～1.10；9级：平均每穗病粒数＞1.10。

Wheat physiological char acte rs show two stages by the dividing line of anthesis.In prophase,it mainly forms tillerings,differentiates the floscules and small heads,forms the base of heads number and grains number.In anaphase,it mainly accumulates effectively dry substance ,makes certain the grains number and grains weight ,so we can confirm the t hree yield factors,that is,heads number,grains number and grain weight.

在小麦生理性状的表现上以扬花期为分水岭分2个阶段，前期主要形成分蘖，分化小花、小穗，决定产量构成的亩穗数和穗粒数；后期表现干物质的有效积累，确定粒数、粒重，从而构成产量的三大因素：亩穗数、穗粒数和粒重。
