玉米秸秆消化率全基因组关联分析

48h体外干物质消化率（48h in vitro dry matter digestibility, 48h IVDMD）是衡量青贮玉米品质的重要指标。为了初步探究玉米秸秆消化率的分子遗传机理,以341份玉米自交系为材料,于2018年在沈阳和通辽种植,收获后测定秸秆48h IVDMD。利用全基因组重测序获得的6 276 612个高质量SNPs进行全基因组关联分析,共检测到153个与玉米秸秆消化率显著相关的SNPs位点（P<1.0×10^-6）,4个SNPs显著水平在P<1.0×10^-8以上;共找到38个秸秆消化率的候选基因,主要涉及细胞生长发育、防御反应和信号转导等生物学功能。     

干法生产UHT豆奶工艺技术研究及应用

棉花不同时期去叶源对库源关系影响的初步研究

通过对棉花不同时期去主茎叶、叶枝叶、果枝叶和全部叶片的研究,初步探讨了棉花叶源对库的影响.结果表明:无论蕾期还是盛铃期,叶片是棉花光合产物的主要来源,没有叶片棉花就不能正常生长,也很难保证其产量;不同部位的叶片中,主茎叶的作用显著,蕾期去主茎叶后株高日增长量减少0.5 cm以上,干物质积累明显下降,盛铃期则导致棉铃大量脱落,成铃平均减少2个以上;去果枝叶的作用相对较小,去叶枝叶几乎无影响.

烘丝温度和时间对生丝机械性能的影响

从刚落下的丝片上摇取小绞丝,分别在25—180℃和30、60、90min下进行干热处理后,测定其机械性能。结果表明:在90—100℃、30—60分钟时,生丝的强伸力、初始模量以及抱合等机械性能都较好,烘丝温度太高,时间太长都会对生丝机械性能产生不良的影响。     

钙对苜蓿幼苗抗寒性及相关生理指标影响的研究

先用50mmol/L CaCl2浸泡图牧吉苜蓿，公农一号苜蓿种子，蒸馏水处理作对照，之后将其幼苗放在低温下胁迫。结果表明：Ca^2 不但能提高图牧吉苜蓉幼苗的抗寒性，而且，也能提高公农一号苜蓿幼苗的抗寒性，同时，图牧吉苜蓿，公农一号苜蓿的超氧化物歧化酶，过氧化物酶，过氧化氢酶等酶活性及脯氨酸与抗坏血酸含量也得到提高。由此推测，Ca^2 提高图牧吉苜蓿，公农一号苜蓿幼苗的抗寒性可能与Ca^2 提高其超氧化物歧化酶，过氧化物酶，过氧化氢酶等酶活性及脯氨酸与抗坏血酸含量有关。     

Stoffbildung, CO2-Gaswechsel, Kohlenhydrat- und Stickstoffgehalt von Winterweizen bei erhöhter CO2-Konzentration und Trocken-streß

Dry Matter Production, CO₂ Exchange, Carbohydrate and Nitrogen Content of Winter Wheat at Elevated CO₂ Concentration and Drought Stress
Methods of mathematical modelling and simulation are being used to an increasing degree in estimating the effects of rising atmospheric CO₂ concentration and changing climatic conditions on agricultural ecosystems. In this context, detailed knowledge is required about the possible effects on crop growth and physiological processes. To this aim, the influence of an elevated CO₂ concentration and of drought stress on dry matter production, CO₂ exchange, and on carbohydrate and nitrogen content was studied in two winter wheat varieties from shooting to milk ripeness. Elevated CO₂ concentration leads to a compensation of drought stress and at optimal water supply to an increase of vegetative dry matter and of yield to the fourfold value. This effects were caused by enhanced growth of secondary tillers which were reduced in plants cultivated at atmospheric CO₂ concentration. Analogous effects in the development of ear organs were influenced additionally by competitive interactions between the developing organs. The content and the mass of ethanol soluble carbohydrates in leaves and stems were increased after the CO₂ treatment and exhausted more completely during the grain filling period after drought stress. Plants cultivated from shooting to milk ripeness at elevated CO₂ concentration showed a reduced response of net photosynthesis rate to increasing CO₂ concentration by comparison with untreated plants. The rate of dark respiration was increased in this plants.
