Abstract

With the purpose of identifying the characteristics of variation in fruit size and seed production (potential and efficiency) of Cedrela odorata L. between sites and progenies established in the ejido La Balsa, municipality of Emiliano Zapata, Veracruz, fruits were harvested from 20 trees in February 2013, preserving the identity of each one. Fruit length and width were measured, seed was extracted and developed and aborted seeds were counted to calculate Seed Production Potential (SPP) and Seed Efficiency (SE). The results showed significant differences between sites and between progenies and for fruit length between sites. The mean values found were: 32.52 mm (fruit length), 18.73 mm (fruit width), 39.9 seeds per fruit (SPP) and 57.51% (SE). The seed of this species for its use should be selected taking into account the production characteristics of crops and outstanding individual trees, in addition, due to the current regulatory restrictions on seed collection, the establishment of trials and plantations for germplasm production is a viable option for forest management of the species.

墨西哥韦拉克鲁斯两个地点的香柏树种子产量变化
2013年2月,为了确定在韦拉克鲁兹州埃米利亚诺萨帕塔市ejido La Balsa建立的雪松遗址和后代之间果实大小和种子产量(潜力和效率)的变化特征,我们从20棵树上收获了果实,并保留了每棵树的特性。测定果实长度和宽度,提取和发育种子,统计流产种子,计算种子生产潜力(SPP)和种子效率(SE)。结果表明,位点间、子代间及位点间果实长度存在显著差异。平均果长32.52 mm,果宽18.73 mm,每果39.9粒(SPP), SE值为57.51%。在选择该树种的种子供其使用时,应考虑到作物和杰出的单株树的生产特点,此外,由于目前对种子收集的管制限制,为种质生产建立试验和种植园是该树种森林管理的一个可行选择。

期刊介绍: Journal of Sustainable Forestry publishes peer-reviewed, original research on forest science. While the emphasis is on sustainable use of forest products and services, the journal covers a wide range of topics from the underlying biology and ecology of forests to the social, economic and policy aspects of forestry. Short communications and review papers that provide a clear theoretical, conceptual or methodological contribution to the existing literature are also included in the journal. Common topics covered in the Journal of Sustainable Forestry include: • Ecology, management, recreation, restoration and silvicultural systems of all forest types, including urban forests • All aspects of forest biology, including ecophysiology, entomology, pathology, genetics, tree breeding, and biotechnology • Wood properties, forest biomass, bioenergy, and carbon sequestration • Simulation modeling, inventory, quantitative methods, and remote sensing • Environmental pollution, fire and climate change impacts, and adaptation and mitigation in forests • Forest engineering, economics, human dimensions, natural resource policy, and planning Journal of Sustainable Forestry provides an international forum for dialogue between research scientists, forest managers, economists and policy and decision makers who share the common vision of the sustainable use of natural resources.
