摘要

Ailanthus excelsa Roxb.属于樗蒲科,是一种快速生长的多用途树种,主要用作饲料和遮荫。它在不同的植株上分别开雄花、雌花和两性花。据观察,在印度(斋浦尔)半干旱地区,雄株在 4 月至 5 月期间叶片生物量较多。在无性状态下,树木的性别无法确定。因此,本研究旨在根据气孔数量、气孔长度、气孔直径、毛状体数量、毛状体长度和毛状体直径等形态描述指标,调查雌雄植株是否存在差异。研究了 20 株雄花和 20 株雌花。数据显示,雄株的毛状体直径(11.91 微米)低于雌株(14.18 微米)。其他参数在统计学上没有显著差异(P>0.05)。毛状体直径(0.042)的模型综合检验系数对改进模型是可靠的,这意味着该模型是最佳拟合模型。为了检验该模型的有效性,进行了 Hosmer 和 Lemeshow 检验,秩方的 p 值(0.405 >0.05)表明上述逻辑模型是最佳拟合模型。进一步研究幼苗期的毛状体直径,然后在成熟期确认植株性别,将有助于建立茴芹性别鉴定的形态标记。

Establishment of morphological markers to differentiate male and female plants in Ailanthus excelsa Roxb. using multiple logistic regression

Ailanthus excelsa Roxb., belongs to the family Simaroubaceae, is a fast-growing multipurpose tree, and used mainly as a source of fodder and shade. It bears male, female, and hermaphrodite flowers on separate plants. It has been observed that male plant has more leaf biomass during April-May in semi-arid regions of India (Jaipur). In its vegetative state, the sex of the tree cannot be identified. The present study has therefore been designed to investigate if there is any difference in male and female plants based on morphological descriptors namely stomata number, stomata length, stomata diameter, trichome number, trichome length, and trichome diameter. 20 plants with male flowers and 20 plants with female flowers have been studied. The data revealed that male plants have lower trichome diameter (11.91µm) than female (14.18 µm) plants. Other parameters do not show any statistically significant difference (P>0.05). The Omnibus Tests of the Model Coefficient obtained for trichome diameter (0.042) is reliable in improving the model, implying that the model is the best fit. To test the validity of this model, the Hosmer and Lemeshow test was performed, and the p-value of chi-square (0.405 > 0.05) indicates that the logistic model obtained above is the best-fit model. Further studies of trichome diameter at the seedling stage and then confirmation of plant sex at maturity level will help in establishing morphological markers in A. excelsa for identification of sex.

期刊介绍: FLORA publishes original contributions and review articles on plant structure (morphology and anatomy), plant distribution (incl. phylogeography) and plant functional ecology (ecophysiology, population ecology and population genetics, organismic interactions, community ecology, ecosystem ecology). Manuscripts (both original and review articles) on a single topic can be compiled in Special Issues, for which suggestions are welcome. FLORA, the scientific botanical journal with the longest uninterrupted publication sequence (since 1818), considers manuscripts in the above areas which appeal a broad scientific and international readership. Manuscripts focused on floristics and vegetation science will only be considered if they exceed the pure descriptive approach and have relevance for interpreting plant morphology, distribution or ecology. Manuscripts whose content is restricted to purely systematic and nomenclature matters, to geobotanical aspects of only local interest, to pure applications in agri-, horti- or silviculture and pharmacology, and experimental studies dealing exclusively with investigations at the cellular and subcellular level will not be accepted. Manuscripts dealing with comparative and evolutionary aspects of morphology, anatomy and development are welcome.
