摘要
以莎车县色素万寿菊主栽品种美国5号为对照,比较4个观赏品种及4个色素新品种田间播种出苗及幼苗生长状况,为2类万寿菊的品种更新及新种质筛选提供参考。结果表明:4个观赏品种间出苗势、出苗指数均存在显著差异,其中印卡Ⅱ与安提瓜的出苗势、出苗指数及移栽成活率均显著或极显著高于奇迹Ⅱ与泰山,但出苗率则极显著低于后二者,分别为75.0%、67.5%,移栽时,各观赏品种根长以泰山最长,达5.98 cm,奇迹Ⅱ的冠幅、株高均极显著高于其他品种,叶面积也较大,安提瓜的冠幅、株高、叶绿素相对含量则均极显著低于其他品种,印卡Ⅱ与泰山的一级分枝数及叶数均极显著高于其他两品种;5个色素品种中佳禾A1、蒙杂1号出苗势均极显著高于其他品种,且蒙杂1号的出苗指数极显著高于其他品种,出苗率以佳禾A2最高,为82.5%,移栽成活率以美国5号最高,为81.3%,移栽时,赤菊圣火根长、冠幅、株高、叶绿素含量均极显著高于其余品种,且其一级分枝数、叶数也较多,佳禾A2幼苗生长相对较弱。2类万寿菊相比,观赏品种的出苗指数、出苗率、移栽成活率整体较高,根较长,茎较粗,叶数较多,而色素品种幼苗的冠幅较大,株高较高。
By taking American No.5,the main variety of pigment marigold in Shache County as the control group,the seedling emergence and seedling growth of four ornamental varieties and four new varieties of pigment were compared in the field,thus to provide reference for the variety renewal and new germplasm screening of the two types of Tagetes erecta.The results showed that there were significant differences in the seedling emergence potential and seedling emergence index among the four ornamental varieties,among which the seedling emergence potential,the seedling emergence index and the transplanting survival rate of InkaⅡand Antigua were significantly higher than those of QijiⅡand Taishan,but the seedling emergence rate was extremely significantly lower than those of the latter two,which were 75.0%and 67.5%,respectively.When transplanting,the root length of each ornamental variety was the longest in Taishan,reaching 5.98 cm.The crown width and plant height of QijiⅡwere significantly higher than those of other varieties,and the leaf area was also larger.The crown width,plant height and relative chlorophyll content of Antigua were significantly lower than those of other varieties.The first-order branch number and leaf number of InkaⅡand Taishan were significantly higher than those of the other two varieties.Among the five varieties of pigment,the seedling emergence potential of Jiahe A1 and Mengza No.1 was significantly higher than that of other varieties,and the seedling emergence index of Mengza No.1 was significantly higher than that of other varieties.The emergence rate of Jiahe A2 was the highest,which was 82.5%.The transplanting survival rate of American No.5 was the highest,which was 81.3%.When transplanting,the root length,crown width,plant height,and chlorophyll content of Chiju Shenghuo were significantly higher than those of other varieties,and the number of first-order branches and leaves was also more,while the seedling growth of Jiahe A2 was relatively weak.Compared with the two kinds of Tagetes erecta,the seedling emergence index,seedling emergence rate and transplanting survival rate of ornamental varieties were higher on the whole,with longer roots,thicker stems and more leaves.However,the crown width and plant height of pigment varieties were larger and higher.
