中文摘要 为了解金黄熊猫(Xanthostemon chrysanthus F.Muell.exBenth)在广州市生长结实表现及其果实与种子特征,本文以广州市天河区龙洞种植的6年生金黄熊猫植株为材料,选取10个单株对金黄熊猫植株生长结实表现、果实及种子特征进行了测定和统计。结果表明:金黄熊猫单株间生长表现差异较大,植株病虫害轻,结实量差异大,果实成熟度不一致,10个单株树高、冠幅、胸径、枝下高、果质量、果序数量范围分别为4~5.3m,2.99~14m²,5.7~9.2cm,0.92.1m,3.4~9.7kg,117~404个;同一个单株及单株间果序大小差异极大,单果序质量、单果序分枝数以及单果序蒴果数范围分别为17.99~166.87g,5~59个,16~161个;500个单果横径、纵径、质量、种子粒数、种子质量变异系数均在10%以上,范围分别为8.18~15.02mm,6.66~14.58 mm,0.512.93g,46~127粒,0.06~0.5g,单果萼片3~8裂,子房室数3~4(稀5)室;种子棕褐色,类三角形、肾形,千粒质量3.34±0.07g,种子长、宽变异系数在13%以上。

英文标题 Preliminary Study on Fruit and Seed Characteristics of Xanthostemon chrysanthus

英文摘要 In order to understand the growth performance, fruit and seed characteristics of Xanthostemon chrysanthus F.Muell.exBenth, 6-year-old Xanthostemon chrysanthus plants planted in Longdong, Tianhe District of Guangzhou City, were selected as testing materials in this paper, The plant performance, fruit and seed characteristics of Xanthostemonchrysanthus were measured and counted.The results show that the growth performance of Xanthostemonchrysanthus is different, plant diseases and insect pests are light, the fruit weight and maturity are different.The range of height, crown diameter, DBH, branch height, fruit weight, a bunch of fruit numberis are 4~5.3m, 2.99~14m², 5.7~9.2cm, 0.92.1m, 3.4~9.7kg and 117~404 respectively.The size of a bunch of fruit varies greatly in plants, and the range of a bunch of fruit weight, a bunch of fruit branches, a bunch of fruit number are 17.99~166.87 g, 5~59 and 16~161 respectively.The variation coefficients of 500 fruits' horizontal diameter, longitudinal diameter, quality, seed grain number and seed quality are above 10%, ranging from 8.18~15.02 mm, 6.66~14.58 mm, 0.512.93 g, 46~127, 0.5g, fruit sepals are 3~8 crack, ovary is 3~4(dilute 5) rooms;Seeds color are brown, triangular, kidney-shaped, one thousand grain weight is 3.34±0.07 g, seed length and width coefficient of variation is over 13%.
