摘要: 以9套含有纯合hp-1hp-2基因的番茄自交系为材料,通过对苗期营养生长和果实色素积累有关特征比较发现:在光周期生长条件下,所有含有hp-1hp-2基因的番茄自交系均表现出相似的特征。即与不含hp基因对照相比:幼苗下胚轴和植株节间显著受到抑制,花期延迟(p<0.01);子叶、胚轴、花萼以及果实中叶绿素、花青素和番茄红素显著提高;hp-1hp-2基因在不同遗传背景下表现度不同。

Abstract: In order to compare the characteristics of nutritional growth and pigment accumulation in different genetic background, nine tomato inbred lines containing pure hp-1 and hp-2 gene were used as experimental materials. The re- sults suggested that NIL (Liger nearly isogenic lines) contained consistent characteristics with hp mutant in photoperiod growth condtion; such as, they had shorter hypocotyls, elevated levels of anthocyanin in cotyledons, hypocotyls and calyces compared with control.Furthermore, all inbred lines containing hp gene had later flowering time(days) and shorter internode; further research on fruit pigment showed that chlorophyll and locopene content were significantly enhanced. But hp-1 and hp-2 gene had inconsistent expressivity in different genetic background.
