Abstract
Morphological characteristics of 45 natural triploid loquats which were 8 years old belonging to four cultivars Dawuxing, Longquan No. 1, Jinfeng, Zaohong No. 3 were systematically compared with corresponding diploids. Compared with diploid adult plants, triploid plants grew exuberantly, had big tree body and few branching, leaf color was dark green with long and dense villi, indenture incision notch of leaf edge was obvious, flower organ turned bigger obviously. The circumferences of trunks, diameters of annual branches, length and width of leaves, length × width of leaves of triploids were 1.7 , 1.4 , 1.6, 2.0, 3.3 times of diploid respectively. The numbers of grown vernal branches and leaf index were 46% and 81% of diploid. Transverse and lengthways diameters of triploid flowers, the flower number of one spica, transverse and lengthways diameters of buds, length of filaments, length and width of anthers, and length of style as well as transverse and lengthways diameters of ovaries, were 2.1,2.3, 1.7, 1.5, 1.4, 1.5, 1.3, 1.3, 1.5, 1.8, 2.2 times of diploid respectively. There had extremely remarkable or notable difference on all above index by variance analysis. Growth advantage and application of triploid plants were discussion.关键词
