为探究西北地区玉米亲本种子活力及适应范围,以我国西北地区41份玉米杂交亲本为试材,设置加速老化(AA)、冷浸(CS)、模拟干旱(D)及盐(S)胁迫处理,以标准发芽试验为对照(CK1),测定种子7 d发芽率及幼苗生物量等指标,结合41份亲本材料在北京、新疆石河子、乌鲁木齐及甘肃酒泉4个生态区的出苗率及种子活力、生物量指标在内的29个参数做了相关性分析。结果表明:分别以20%PEG 6000(0.033 mol/L)和200 mmol/L NaCl处理模拟干旱和盐胁迫,选取80%的种子能正常发芽的处理浓度作为筛选依据,以此标准来评价亲本种子活力是可行的。供试材料中的30份亲本标准发芽率达到85%的国家标准要求;11份材料发芽率>92%,高于玉米单粒播发芽标准。冷浸处理后,35份亲本(占比85%)的发芽率与对照(CK1)无显著差异,其中4个亲本冷浸后发芽率比CK1升高1%~18%。41份亲本的种子耐老化能力普遍较差,加速老化处理的种子发芽率最高仅为44%;200 mmol/L NaCl胁迫条件下,10个亲本的发芽率被显著抑制,20%PEG 6000条件下8个亲本发芽率受到显著抑制;另有10个亲本的发芽率在模拟干旱(20%PEG 6000)和盐(200 mmol/L NaCl)胁迫下均显著升高(P≤0.05);模拟干旱胁迫可显著诱导18份亲本幼苗根系的发育,其中12份亲本根重显著增加(P≤0.05)。不同亲本材料在4个气候区的出苗率均表现出较大的变异,且各气候区的出苗率与冷浸发芽率的相关性均达到极显著相关。

Quaternary approach has been receiving more and more attention due to its effectiveness in improving solar cell performance, while synthesis/selection of the fourth component is yet a key issue. Herein, we report a chlorinated phthalimide based donor polymer(namely Ph I-Cl) having an ultra-wide bandgap(2.10 e V) and a deep HOMO(-5.58 e V) level. Addition of Ph I-Cl as the third component of PM6:Y6 and the fourth of PM6:Y6:PC71BM increases both hole and electron mobilities and gives rise to more balanced charge carriers mobilities. Both the short-circuit current-density and fill-factor are increased and open-circuit voltage is well maintained, delivering 17.0% and 18.1% efficiencies, respectively. These results demonstrate that chlorination on the side thiophene of phthalimide-based donor polymer is a way to make deep HOMO and ultra-wide bandgap donor polymer guest used for highly efficient ternary and quaternary strategies.
