摘要
在西爪哇和北苏门答腊的6个地点，采用20 m × 50 m的取样样地，对鳞片树蕨Cyathea污染物不定根的生产潜力进行了研究。研究记录的数据包括种群密度、单株高度和直径、不定根体积和环境因素。树苗高度在2 m以下的种群密度最高。成虫密度为26 ~ 36株/100 m2。在缓坡上以成年林分为主的种群中，不定根平均体积最大，为108,760.70 cm3/株;在幼树组成的种群中，不定根平均体积最小。统计分析结果表明，不同生境下的不定根产量有显著差异。干径、株高与不定根体积呈显著正相关，与株高呈显著正相关。
KAJIAN POTENSI PRODUKSI AKAR ADVENTIF PAKIS POHON Cyathea contaminans (CYATHEACEAE) DI JAWA BARAT DAN SUMATERA UTARA
Study on production potential of adventitious root of the scaly tree fern Cyathea contaminans was conducted in six locations in West Java and North Sumatra using 20 m x 50 m sampling plot. Data recorded in the study consisted of population density, individual heights and diameter, volume of adventitious roots and environmental factors. The highest population density was found in a population that consisted of saplings with the height of less than 2 m tall. While population with adult plants has the density of 26–36 individual/100 m2. The wighest average volume of adventitious root per individuals was found in a population that dominated by adult stands and lies on a gentle slope at 108,760.70 cm3/individuals, while the lowest was in a population that consisted of saplings. The result statistical analysis showed that production of adventitious root were significantly different in different habitat. Moreover, there was positive correlation between trunk diameter and individual height with the volume of adventitious root, and between the diameter with individual height.
