Effects of Different Pelleted Tobacco Seeds on Seedling Quality

摘要: 第二代包衣种较第一代包衣种抗压强度提高1.5倍,裂解速度提高3倍;与第一代包衣种和裸种(对照)相比,出苗率分别提高23.6%、28.5%;出苗整齐度提高50.7%和53.0%;七叶一心时烟苗茎粗分别增加7.8%、3.8%,侧根数分别增加14.9%、9.1%;单株地上部干重分别提高11.6%、29.7%,地下部干重分别提高37.8%、34.8%。

Abstract: The new pelleted seed had 1.5 times more compressive strength and three times faster on splitting speed than general used pelleted seed.Compared the new pelleted seed with the general used pelleted seed and the normal seed(CK), the percentage of the germination enhanced 23.6% and 28.5%, the uniformity of the seedling improved 50.7% and 53.0%.At seven leaves stage the stem girth increased 7.8% and 3.8%, and the number of the side root increased 14.9% and 9.1%, the dry weight of the shoot increased 11.6% and 29.7%, and the dry weight of the root increased 37.85 and 34.8%, respectively.
