不同施肥水平下黍子根系对干旱胁迫的生物学响应研究表明，无论施肥与否，拔节期或抽穗期干旱胁迫均会使黍子根重、根长、根活力、次生根数、根系SOD活性及株高与地上部干重明显降低，MDA含量明显增高；水分胁迫解除后，黍子根系增长迅速，表现出明显的补偿效应和根系对水分反应敏感的特点，但干旱造成的不利影响在后期未能完全补偿。

Five main stalk crops planted in northern China including wheat, corn, broomcorn, soybean, and millet, were chosen to be the samples of the experiments. About seven morphological traits (such as plant height, ear length, ear weight, moisture content and so on) were measured in the crop mature period. The maximum shear force during shearing process, through static test equipment, at the second internode of the basal stalk, was recorded. And shear strength of each crop was calculated to find the differences of shear strength among different crops. The optimal regression models of shear force and morphological traits were obtained by multiple linear regression method with Statistics Analysis System. The equation based on the regression models was constructed.

本文以北方主要茎秆作物（小麦、玉米、高粱、大豆、谷子）为研究对象，试验测定了成熟期茎秆基部第二节间的最大剪切力及株高、穗长、穗重、含水率等七种形态特性指标，获得了静载情况下相关样本的剪切强度；分析比较了不同茎秆作物剪切强度的差异性，并利用SAS软件对茎秆作物剪切力与形态特性指标进行了多元线性回归，得到了剪切强度对形态特性指标的最优回归方程。

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。

PmMYB is a typical R2, R3-MYB transcription factor with its 2 typical DNA-binding domains (amino acid sites of 13-63 and 66-114).The multiple alignment of R2, R3 amino acid repeat regions of MYB genes among broomcorn millet, rice, corn, loblolly pine, Arabidopsis, capsicum, upland cotton, barley and aubergine indicates that R2, R3 repeat regions are very conserved. The phylogenetic analysis based on amino acid sequence shows that MYB genes are highly divergent with similarity ranging from 32% to 84%.
