The cell wall composition and structure of the maize stalk directly affects its digestibility and in turn its feed *** studies of stem quality have focused mostly on common maize germplasm,and few studies have focused on high-oil cultivars with high grain and straw *** of the genetic basis of cell wall composition and digestibility of maize stalk using high-oil maize is desirable for improving maize forage *** the present study,a high-oil inbred line(By804)was crossed as male parent with the maize inbred line B73 to construct a population of 188 recombinant inbred lines(RILs).The phenotypes of six cell-wall-related traits were recorded,and QTL analysis was performed with a genetic map constructed with SNP *** traits were significantly correlated with one another and showed high broad-sense *** 20 QTLs mapped,the QTL associated with each trait explained 10.0%–41.1%of phenotypic *** half of the QTL each explained over 10%of the phenotypic *** results provide a theoretical basis for improving maize forage quality by marker-assisted selection.

The new complexes, [PdCl{C5H4FeC5H4CHRN=CHC4H3O}（Ph3P）] （R= H, CH3） were synthesized via two novel Schiff bases （C5H5FeC5H4CHRN=CHC4H3O, R= H, CH3） with lithium tetrachloropalladate （Ⅱ）, and characterized by IR, elemental analysis, ^1H NMR. Complex 5a was further determined by X-ray single crystal diffraction. We found that it contained an intramolecular N→Pd coordination in the compound 5a, and the palladium atom was bound to the unsubstituted Cp ring. The Pd-N, Pd-C （I） and Pd-O bond lengths were 2.121 （3）, 2.008 （4） and 2.990 ）A, respectively.

Tree species-abundance in forests is a function of geographical area and climate, although it is not clear whether such relationships apply to mass islands. We examined the spatial pattern of tree species in mass islands along the coast of Zhejiang, East China Sea using the Preston model, to identify the relationships between tree communities and climatic conditions. The results show that：（1） the biogeographical distribution of tree species-abundance conformes to Preston＇s log-normal pattern, and is in accordance with the findings in both tropical rainforests and estuarine forests;（2） the climatic factors related to tree communities in mass islands are similar to that of the subtropical zone, including the major species of evergreen needle-leaf, broad-leaf and deciduous broad-leaf forests. We conclude that the Preston model can be applied to the trees of mass islands and thus facilitate the systematic ecological researches of vegetation species＇ composition in subtropical zone.

采用电絮凝技术处理高温超稠油采出水,考察了反应时间、电流密度和极板间距对电絮凝处理效果的影响,通过响应面法对电絮凝处理超稠油采出水工艺条件进行了优化,并对电絮凝过程净化机理和电极钝化的影响因素进行了研究。研究表明,电絮凝技术能有效去除高温超稠油采出水中的油、COD和SiO_(2),反应时间对COD和SiO_(2)去除率影响极显著。当反应时间为27.2 min,电流密度为8.6 mA/cm2,极板间距为1.8 cm时,COD和SiO_(2)去除率分别为81.0%和100%。电絮凝对采出水起净化作用的是铝离子与OH-结合生成的多核羟基铝络合物胶体。采出水中Cl-含量的增加使铝板的钝化程度略有减弱,而SO42-和HCO3-含量的增加使铝板的钝化程度增加;当采出水呈中性时,铝板的钝化程度最高。
