In intercropping systems,high-positioned crops often exert shading stress on low-positioned crops,thus affecting the agronomic characteristics of the low-positioned *** study determined the mechanisms of photosynthetic,physiological and yield variations among peanut cultivars under shading *** peanut cultivars,S60,C4,P12,and YS151,were grown in the field and subjected to shading stress for 77 days during reproductive stages.S60 and P12 showed lower yield and reduced biomass accumulation than C4 and YS151 under shading *** stress induced higher antioxidant enzyme activities in S60 and P12,relative to C4 and *** shading stress,S60 and P12 showed a higher lighttrapping capability than C4 and YS151,which was associated with changes in chlorophyll(Chl)a and b contents,and Chl a/b *** net photosynthetic rate,stomatal conductance and transpiration rates of C4 and YS151 were decreased,but the intercellular CO_(2)concentration increased under shading *** results demonstrated that non-stomatal limiting factors decreased the photosynthetic capacity of peanut under shading *** maximum photochemical efficiency of PSII(F_(v)/F_(m))and non-photochemical quenching(NPQ)were higher in S60 and P12 than in C4 and YS151 under shading *** results suggest that S60 and P12 could absorb more light energy from weak light environments for photosynthesis than C4 and YS151 and dissipate the excess energy in the form of heat to improve their light protection *** study explains the inter-variety differences in shading stress tolerance in peanut and provides physiological parameters for guiding the selection of shade-tolerant cultivars.

Starch content is a key factor affecting sorghum grain quality. The research of sorghum grain starch accumulation and the related synthesis enzyme activities has great signiifcance for understanding the mechanisms of starch metabolisms. The differences between a high and a low starch content sorghum hybrids （Tieza 17 and Liaoza 11, respectively） in grain starch accumulation and the related synthesis enzyme activities were assessed following imposition of water stress during lfowering stage. The total starch, amylase and amylopectin accumulation all decreased at the mid-late stage of grain iflling under drought stress during lfowering stage. The maximum and mean accumulation rates also decreased. During grain iflling, soluble starch synthase （SSS）, granule-bound starch synthase （GBSS）, starch branching enzyme （SBE）, and starch debranching enzymes （DBE） activities were all affected, though differently. Drought stress reduced starch accumulation in a larger extent for Tieza 17 than Liaoza 11. Drought stress during lfowing stage reduced starch synthesis enzyme activities, thus reducing starch accumulation in grains, and the differences between starch components were also demonstrated under drought stress.

China

The historical changes in rice yields across China were explored. The physiological mechanisms and genetic basis of the erect and large panicle super-high-yield plant type model for breeding japonica super rice were analyzed mainly on the panicle type, number of large vascular bundles （LVB） in the panicle neck, and the panicle type index （PTI）. In the production point of view, we suggested that, for the breeding of super-high-yield japonica rice, the erect panicle types with more LVB numbers in the panicle neck and superior upper grains in the secondary branches would be the key factors. The information has potential significance in the rice breeding and productivity not only in China but also throughout the rice production areas of the world.

以高粱耐盐品种(辽杂15号)和盐敏感品种(龙杂11号)为材料,人工气候箱(湿度60%,光照/黑暗为12h/12h,光照强度为134μmol·m-2·s-1,昼/夜温度为28℃/25℃)内营养液培养。从3叶期开始进行不同浓度NaCl(0,50,100,150,200mmol·L-1)处理,研究盐胁迫下高粱幼苗保护酶系统的响应。结果表明:在盐胁迫下,高粱幼苗的O2-和MDA含量有所增加,其增加幅度随着NaCl浓度的增加而增大。与盐敏感品种龙杂11号相比,耐盐品种辽杂15号的O2-和MDA含量均处于较低水平,受到盐胁迫后的增幅较小。高粱幼苗受到盐胁迫后,SOD(超氧化物歧化酶)、POD(过氧化物酶)、CAT(过氧化氢酶)和APX(抗坏血酸过氧化物酶)活性均有所提高,其提高的幅度随着NaCl浓度的增加而增大。盐胁迫下,辽杂15号SOD、POD、CAT和APX活性的增幅较龙杂11号大。可见,在盐胁迫下耐盐高粱品种辽杂15号表现出较高的抗氧化能力,能够及时清除过量的活性氧,避免了活性氧的过量积累,使细胞膜脂过氧化程度维持在较低水平。
