喀西茄(Solanum khasianum C. B. Clarke)是茄子近缘野生种,具有珍贵的抵抗生物胁迫及非生物胁迫的基因。以10 份栽培茄材料作母本与喀西茄进行杂交,并采用一次授粉、重复授粉、花柱短截、混合授粉及嫁接后授粉等授粉方式,研究获得栽培茄与喀西茄种间杂交种的最佳方法。结果表明:采用嫁接后授粉可以提高杂交结果率,并且得到了L81 与喀西茄的F1;对F1 苗期植株进行SSR 分子鉴定...
Tomato chlorosis virus (ToCV) is a plant virus that is mainly propagated by Bemisia tabaci in a semi-persistent and non-circulative manner.It has a wide range of host plants,and has been reported in m...
为探究马铃薯专用生长模拟模型SOLANUM对甘肃省中东部马铃薯产量预测的适用性,并分析该地区主要气候因子对马铃薯产能差的影响。本试验以3个马铃薯基因型为参试材料,利用SOLANUM模型计算并校准甘肃省天水市和定西市马铃薯模型参数,并对SOLANUM模型进行统计学的模型评价。结果表明,SOLANUM模型在甘肃省适用性评价中,产量和冠层覆盖度模拟结果相对均方根误差(RRMSE)均在16%~76.2%之...
以香瓜茄(Solanum murcatum)主栽品种"阿斯卡"为材料,在日光温室条件下进行了不同生育时期和施肥处理下叶片气体交换特性及其日变化、光合速率对光强和CO2响应的研究。结果表明:反季节生产条件下香瓜茄叶片光合色素含量在生育期内先升高后降低,于开花坐果期至果实膨大期达到峰值,有机肥处理的叶绿素含量显著高于不施肥处理,叶绿素a/b值约2.6,具有弱光适应特征。香瓜茄生育期中叶片气孔导度(Gs...
In 2001, genetically modified potatoes carrying the ac2 gene were developed. This gene was originally found in amaranth seeds (Amaranthus caudatus) and is expressed into the fungicidal peptide Ac-AMP2...
Changes in Hsp70 gene expression and protein level were studied in three Solanum spp. genotypes in response to short-term high and low temperatures and to infection by powdery mildew. Development of ...
The leaf extract of Solanum torvum Sw. (Solanaceae) was evaluated for its fungitoxic activity against Fusarium sacchari (E.J. Butler & Hafiz Khan) W. Gams (1971). The leaf extract was found to inhib...
The effect of fertilisation with fermented pig slurry on the quantitative and qualitative parameters of two kinds of tomatoes was assessed by means of pot trials. These trials were carried out betwe...
Soil and water salinization are affecting an increasing number of countries in the world, especially in arid and semi-arid regions, and cause sensible reductions of agricultural land extension and of ...
Seeds from atrazine resistant plants of black nightshade (Solanum nigrum L.) were collected at the railway station Prague-Vršovice, seeds from susceptible plants in Vyšehořovice (Prague...
We report a feasibility study for expressing the LTB protein (Escherichia coli heat-labile enterotoxin B subunit) via Agrobacterium-mediated transformation of tomato (Solanum lycopersicum L.). We prod...
Great efforts are currently being devoted to studying the use of transgenes to confer resistance to phytopathogenic fungi. Snakin-1 is a broad-spectrum antimicrobial peptide isolated from Solanum that...
This study concluded that high concentration of N, P and K in the nutrient solution gave higher total yield and tomato fruit weight than the control nutrient solution in tuff culture grown tomato. Hig...
【目的】利用盐敏感的栽培种番茄(Solanum lycopersicum)M82与耐盐的野生种潘那利番茄(Solanum pennellii)LA716构建的渐渗系群体,对苗期耐盐QTLs进行定位,并初步分析QTL遗传效应和互作效应。【方法】将4片真叶幼苗移栽到1/2浓度的Hoagland营养液中,按一定浓度逐日增加盐,至终盐浓度700 mmol?L-1 NaCl+70 mmol?L-1 CaCl...
