为发掘能应用于生产实践的辣椒半矮秆新种质,以辣椒自交系6421和其EMS诱变获得的半矮秆突变体E483为试验材料,对突变体表型、生物量、光合特性、生理指标及遗传规律进行分析,明确其半矮秆突变特征。结果表明,突变体E483植株节间距缩短,各发育时期植株株高约为6421的一半;叶片变小,叶面积极显著低于6421,叶色深绿;花朵变小,花瓣长、花药长、柱头长和花丝长均极显著低于6421;果实变短变宽,单果鲜质量和单株坐果数极显著低于6421;根长变短,根深、根宽、根开展面积均极显著低于6421,根系活力极显著高于6421;幼苗鲜质量及干质量均极显著低于6421,鲜质量根冠比显著低于6421;叶片中叶绿素、类胡萝卜素含...

In order to explore new pepper semi-dwarf germplasm that could be applied to production,pepper inbred line‘6421’and its EMS induced semi-dwarf mutant‘E483’were used as test materials;conducted analysis on phenotype,biomass,photosynthetic characteristics,physiological indexes and inheritance of mutant;and confirmed its semi-dwarf mutation characteristics.The results showed that the internode distance in plant of mutant‘E483’was shortened,and plant heights in each development period were about half of‘6421’.The leaves became smaller,and l...
