张家口地区谷子主栽品种萌发期抗旱性评价

为鉴评张家口地区主栽常规谷子品种和杂交谷子品种的萌发期抗旱性,采用不同浓度(0、5%、10%、15%、20%和25%)的聚乙二醇(PEG-6000)模拟干旱胁迫,对8份主栽品种的发芽率、发芽势、发芽指数、芽长、芽重等指标进行了测定,结果表明:(1)在非PEG胁迫(CK)下,各品种的发芽特性不一致,常规谷子较杂交谷子的种子萌发期短;(2)低浓度PEG(5%)处理可在一定程度上提高部分谷子品种的发芽率和发芽势;之后随胁迫加剧,种子萌发受抑制程度也随之加剧,各项指标均呈显著下降趋势;(3)应用模糊数学隶属函数法对8份谷子品种的抗旱性进行综合评价,结果显示张杂谷5号抗旱性最强,小质小红谷和张杂谷10号次之,张杂谷3号抗旱性最差。     

Segregation of form, color, movement, and depth: anatomy, physiology, and perception

Anatomical and physiological observations in monkeys indicate that the primate visual system consists of several separate and independent subdivisions that analyze different aspects of the same retinal image: cells in cortical visual areas 1 and 2 and higher visual areas are segregated into three interdigitating subdivisions that differ in their selectivity for color, stereopsis, movement, and orientation. The pathways selective for form and color seem to be derived mainly from the parvocellular geniculate subdivisions, the depth- and movement-selective components from the magnocellular. At lower levels, in the retina and in the geniculate, cells in these two subdivisions differ in their color selectivity, contrast sensitivity, temporal properties, and spatial resolution. These major differences in the properties of cells at lower levels in each of the subdivisions led to the prediction that different visual functions, such as color, depth, movement, and form perception, should exhibit corresponding differences. Human perceptual experiments are remarkably consistent with these predictions. Moreover, perceptual experiments can be designed to ask which subdivisions of the system are responsible for particular visual abilities, such as figure/ground discrimination or perception of depth from perspective or relative movement--functions that might be difficult to deduce from single-cell response properties.     

Mineralogy, petrology, and surface features of lunar samples 10062,35, 10067,9, 10069,30, and 10085,16

The primary rocks are a sequence of titanium-rich basic volcanics, composed of clinopyroxene, plagioclase, and ilmenite with minor olivine, troilite, and native iron. The soil and microbreccias are respectively loose and compacted mixtures of fragments and aggregates of similar rocks, minerals, and glassy fragments and spheres. Impact events are reflected by the presence of shock metamorphosed rock fragments, breccias, and glasses and their resulting compaction to form complex breccias, glass-spattered surfaces, and numerous glass-lined craters. Chemistry of the glasses formed by the impact events is highly variable, and the high iron and nickel content of a few moundlike features suggests that at least some of the projectiles are iron and nickel-rich meteorites.     

Research and development, productivity, and inflation

R & D, through its effects on the rate of productivity increase, can significantly restrain the rate of inflation in the medium and long run. High rates of inflation damage the workings of the price system and impair the efficiency of practically all economic activities, including R & D. Findings suggest that the percentage increase between 1969 and 1979, in total real R & D expenditures, has been exaggerated due to the inadequacy of the gross national product deflator as applied to R & D.
