大豆微核心种质在黄淮地区的区域适应性分析
大豆 微核心种质 AMMI 双标图
2011/6/3
运用主效可加互作可乘(AMMI)模型，对黄淮地区3省两年的60份大豆微核心种质数据进行了分析，目的是对参试种质的环境稳定性和适应性进行评价。结果表明，(1)株高、有效分枝数、百粒重和产量性状的基因型与环境互作效应(G×E)占总平方和的16.73%~24.57%，均达到极显著水平，说明有进一步进行稳定性分析的必要。(2)不同种质不同性状在各试验点具有不同的适应性，部分种质某一性状具有广泛适应性、而部...

应用隔年卫星遥感影像评估区域麦稻连作水平
麦稻连作 卫星遥感 连作指数 连作水平评估
2011/12/9
为探讨利用稀缺或隔年卫星遥感影像估算大地理区域麦稻连作水平的可行性，以江苏省常熟市为例，利用隔年TM卫星遥感影像，提取小麦和水稻种植面积并分析了麦稻连作水平。在解译隔年稻麦卫星遥感影像获取麦稻连作面积信息的基础上，运用马尔可夫链建模方法构建麦稻连作水平评估模型来估算麦稻连作水平，并用GPS 实地取样调查对估算精度进行验证。结果表明，常熟市麦稻连作指数为0.76，即有76%的小麦连作水稻，估算精度在...
两系杂交小麦杂优3号的灌浆特性及杂种优势研究
两系杂交小麦 灌浆特性 粒重 杂种优势
2011/12/9
为给低温敏感雄性不育（BNS）型两系杂交小麦的选育及高产栽培提供依据，对BNS型两系杂交小麦杂优3号的灌浆特性及其杂种优势进行了分析。结果表明，在整个灌浆过程中，杂优3号籽粒干重变化呈“S”曲线，干重增幅大于父本Bh001，具有明显的超高亲优势。与对照百农矮抗58相比，杂优3号在灌浆后期的优势较为明显。晚播可提高杂优3号最终千粒重和籽粒最大灌浆速率。杂优3号的籽粒灌浆速率呈正态变化曲线，在灌浆渐增...
为大量扩繁东北刺人参不定根提供可靠的理论依据。【方法】以东北刺人参不定根为外植体，研究在液体振荡培养中，NAA、IBA以及蔗糖浓度对东北刺人参不定根生长的影响。【结果】不同生长素及浓度对东北刺人参不定根的影响中，IBA对促进东北刺人参不定根的生长效果优于NAA，当IBA浓度为3~4 mg/L时，适合不定根生长，培养不定根的IBA浓度为3 mg/L；在培养基MS+IBA 3 mg/L中提高蔗糖浓度到...

Rubisco活化酶(RCA)是一种可激活光合作用关键酶Rubisco的伴侣蛋白，可通过对Rubisco的活性调节决定植物的碳同化效率。为了研究玉米ZmRCA1的多态性，本研究参考GenBank中编码玉米Rubisco活化酶的ZmRCA1基因组序列设计引物对玉米微核心种质的95份自交系的ZmRCA1进行测序，获得长约1 680 bp的基因组序列。多态分析表明，在1 680 bp的区间内共发现22个...
为合理利用氮肥,进一步提高大麦产量和品质,以扬饲麦3号、港啤1号、扬农啤2号和Frankin共4个品种为供试材料,研究了0(CK),90(NL),180(NM)和270kg/hm2(NH)4个氮肥水平下冬大麦干物质和氮素积累、转运及对籽粒贡献的规律。结果表明,随着施氮量的提高,大麦干物质花前积累量呈增加趋势,积累率及对籽粒的贡献率呈下降趋势,各器官的转运量在NM处理(180kg/hm2)范围内呈增...
