摘    要:白骨壤1年生幼苗的株高、基径、根长、呼吸根高、叶面积以及根、茎、枝、叶、胎生苗和全株生物量等计量指标,呈现算术平均值>中值>众值组段中点的规律,符合正偏态分布节数、叶数、呼吸根数、胎生苗数等计数指标的算术平均值和中值相等,二者大于或等于众值组段中点.研究发现白骨壤1年生幼苗能生长指状呼吸根以及开花、结果和发育胎生苗,而且胎生苗成熟后直接萌发形成新的幼苗.根据实测的数据,采用一元线性回归、多元线性回归和非线性回归拟合了白骨壤1年生幼苗主要形态因子和生物量的回归模型

关 键 词:白骨壤,幼苗,形态特征,生物量,回归模型

Abstract:The investigation of one-year-old Avicennia marina seedlings cultivated in sand beds irrigated with natural sea-water indicates that some quantitative indices such as plant height, basal diameter, root length, pneumatophore height and leaf area and weights of root, stem, branch,leaf, viviparous seedlings and whole plant show a pattern of their arithmetic mean> median>median of mode interval, which accords with poSitive deviate distribution. The arithmetic mean of some enumerative indices Such as numbers of node, leaf, pneumatophore and viviparous seedling of anllual seedling equals to their median. both of which are equal to or larger than the median of mode intervals. It also shows that annual Avicennia marina seedlings can grow the pneumatophores. flower and fruit, and propuced viviparous seedlings which after maturation,can directly develop into new seedlings. Based on the data obtained, 30 regressive models on the morphological factors and hiomass of annual A. marina sablings are built up using linear,multilinear and non-linear regression.
Keywords:Avicennia  marina  Seedling  Morphological character  Biomass  Regressive model
