Through biological, phenological, geographical and distributionalanalyses of drought resistance and tolerance of broomcorn millet, it canbe seen that this crop has a good yield potentialin south Ningxia. Inthe last part of the paper the author ...

最后对提高糜子生产提出如下几点建议： 1、加强对糜子的科研工作，特别要注意高产栽培的研究； 2、在品种普查基础上，对宁南山区的糜子品种资源进行一次收集整理工作； 3、种子部门应繁殖经营糜子品种，特别要留足小日月救灾品种； 4、大力推广固原县鸦儿沟生产队糜子高产经验； 5、用少量尿素作种肥，增产显著，可普遍采用。

The result obtained from mean vector multiple comparison showed the agronomic properties of water caltrop as affected by different landraces were significant. The Taitung landrace was significantly different from other landraces.

由平均值向量多重比较可得知，不同地方品种间的综合表现有显著的差异存在，台东地方品种与另外7个地方品种有显著差异，而湖山地方品种则只有与官田有显著差异。

Variations among rice cultivars in lead tolerance, uptake and translocation Under the soil treated with 800 mg kg〓 Pb, the effects of Pb on rice growth and development varied greatly with cultivars, with some cultivars significantly promoted, some significantly restrained, and others no obvious change.

五、水稻不同品种对铅吸收、分配的差异在土壤铅浓度为800mg kg〓的条件下，水稻不同品种的生长发育对铅处理的反应差异很大，部分品种受到明显抑制，部分品种受到明显促进，而另一些品种没有明显变化。

Four Hyacinth varieties were used in this experiment,namely the pink species Anna Marie, the yellow species City of Haarlem, the pink-white species Lady Derby, and the blue species Blue Jacket.

本实验以风信子的四个栽培品种为供试材料，分别为粉红色品种安娜玛丽、黄色品种海姆之城、粉白色品种杜比女士、蓝色品种蓝马甲。

The results showed that net photosynthetic rate P(subscript n, transpiration rate T(subscript r, stomatal conductance G(subscript s, intracellular concentration of CO2 C(subscript i, water use efficiency of cultivars and the light saturation point in leaves of 5 cultivars were different and had obvious differences, and the light compensation point was similar. Diurnal change of net photosynthetic rate among cultivars were different, three cultivars showed twin-peaked curve with an obvious midday-depress, others showed single peak curves.

结果表明：不同品种的净光合速率P(下标 n、蒸腾速率T(下标 r、气孔导度G(下标 s、胞间CO2浓度C(下标 i、水分利用率和光饱和点之间的差异明显，各品种的光补偿点均较低；净光合速率的日变化也存在明显的品种间差异，有3个品种呈&中午降低型&的双峰曲线，2个品种呈单峰曲线。

We put forward a new viewpoint that the purity of seed selection keeps the balance with the DNA polymorphism demand. The research aim at oak silkworm seed selection was to determine how to keep the balance between improving cultivar purity and keeping the genetic diversity within cultivar.

对品种选育的纯度与DNA多态性需求的平衡进行了讨论，并分析了对柞蚕品种选育的启示，提出了柞蚕品种选育的下一步的研究目标：寻找提高品种纯度与保持品种内的遗传多样性的平衡点。

The root hair morphology of cv. RM109 was observed and compared. The results indicated that in the distance of 1 cm to the apical of seed root, the number of root hair of RM109 was 19% of cv. Oochikara, and the root diameters were not different from cv. Oochikara; in the distance of 8 cm, the number of root hair and the root diameters of RM109 were 45% and 79% of cv. Oochikara, in the distance of 3 cm, the length of the longest root hair was 33% of cv. Oochikara; but the length from the apical of the seed root to root hair initiation was not different.

根毛观察比较显示，距种子根根端1 cm处的RM109根毛数是&大力&品种的19%，差异极显著，根直径与&大力&品种差异不显著；距根端8 cm处的RM109根毛数和根直径分别是&大力&品种的45%和79%，二者差异极显著；距根端3 cm处，RM109最大根毛长是&大力&品种的33%，差异极显著；RM109种子根根端到根毛发生区的长度，与&大力&品种的差异不显著。

It was found that the development had the distinguishing features of hybrid rice occupying dominant and ever increasing position, the hybrids derived from V20A and Zhenshan 97A being the main body of hybrid rice, conventional rice varieties being gradually replaced by good quality ones, the number of varieties increasing with plant area of a single variety decreasing, over 68% of va...

湖南省晚稻品种的演变呈现出如下特点：杂交稻占主导地位，且比例不断扩大；威优系统和汕优系统构成杂交稻主体；常规稻主栽品种逐步实现优质化；品种数目不断增多，单个品种播种面积减少；超过 68%的品种年播种面积低于 670 0hm2 。对产生这些现象的原因进行了探讨。
