摘要
在重新造林项目或种植园发展中选择林木作为种植材料,可以根据木材工业的现有需求,并支持国家绿化计划。它以自然适应为基础,考虑到对主要场地条件的适应性,确保高存活率;种植目的;种植存量的可用性;以及商业价值。因此,对菲律宾Banahaw de Lucban山东北坡的正树和母树进行了选择和测绘,以确定潜在的种子生产区作为优质种植材料的来源。编写了用于传播的信息材料。22个种,65个个体,代表番荔枝科、Fabaceae、壳斗科、Clusiaceae、Meliaceae、Myrtaceae、Podocarpaceae、Sapindaceae、Sapotaceae、Symlocaceae、Theaceae和Tiliaceae科,与周围的树木相比,生长旺盛,在高度和直径方面具有优势。表型特征受温度、降雨量、土壤和海拔高度的影响。正树的最高种群分布在中到陡坡上。低海拔地区有利于生长的土壤。物种多样性为2.00,700 masl和800 masl的树木多样性适中。然而,根据DENR第11号行政命令(DAO)2017年第11号和国际自然保护联盟(IUCN)的规定,有11种物种受到威胁。
Plus and Mother Trees in Mt. Banahaw de Lucban, Quezon, Philippines
The selection of forest trees as planting materials in reforestation projects or plantation development could be based on the existing needs of the wood-based industry, and in support of the National Greening Program. It is anchored on natural adaptation to ensure high survival rates considering suitability to prevailing site conditions; purpose for planting; availability of planting stocks; and commercial value. Thus, selection and mapping of plus and mother trees at the northeastern slope of Mt. Banahaw de Lucban, Philippines were conducted to determine potential seed production areas as sources of quality planting materials. Information materials were developed for dissemination. Twenty-two species with 65 individuals representing families of Annonaceae, Fabaceae, Fagaceae, Clusiaceae, Meliaceae, Myrtaceae, Podocarpaceae, Sapindaceae, Sapotaceae, Symplocaceae, Theaceae and Tiliaceae showed vigorous growth and superiority in height and diameter compared with the surrounding trees. Phenotypic characteristics are influenced by temperature, rainfall, soil and elevation. Highest population of plus trees was distributed in moderate to steep slope. Favorable soils for growth were found at lower elevations. Species diversity of 2.00 showed moderately diverse plus trees at 700 masl and 800 masl. However, 11 species were found threatened as listed on DENR Administrative Order (DAO) No. 11, s. 2017 and the International Union for Conservation of Nature (IUCN).
