中文摘要	为探讨珍稀树种蒜头果(Malania oleifera)果实与种子的基本性状及其在石漠化山区的适应性,测定了其果实与种子的外部形态、个体质量、果实出种率和种子出仁率等,并在桂西南石漠化山区选择4种立地类型(裸地、草丛、灌丛和疏林)开展直播造林试验。结果表明:蒜头果果实和种子的鲜重、高度、宽度和出种率或出仁率的平均值分别为(21.30 4.25) g和(9.351.68) g, (39.312.77) mm和(26.12 1.80) mm、(35.192.25) mm和(28.611.55) mm及44.21%3.21%和70.43%4.25%,种子鲜重与果实鲜重、种子出仁率与种子鲜重存在一定程度的正相关;在4种立地类型中,种子萌发率为灌丛>疏林>草丛>裸地,2年生幼苗的存活率为疏林>灌丛>草丛>裸地,株高总生长量为疏林>灌丛>草丛>裸地,基径总生长量为疏林>灌丛>草丛>裸地。根据试验结果,在桂西南石漠化山区,蒜头果在灌丛和疏林适应性较好而可以直播造林,但在草丛和裸地适应性较差而不宜直播造林。
英文摘要	In order to explore the fruit and seed traits and adaptability of Malania oleifera,a rare tree species,to rocky desertification mountain,we investigated the morphology and weight of fruit and seed, seed rate and seed kernel rate of M. oleifera. Reforestation through direct seeding experiment was also conducted in four site types (bare land,grassland,shrub land and open forest land) to evaluate the adaptability of M. oleifera to rocky desertification region in the southwest of Guangxi. The results showed that the average fresh fruit weight of M. oleifera was (21.304.25) g and its average height, width, fruit seed rate was (39.31 2.77) mm, (35.192.25) mm and 44.21%3.21%,respectively. The mean weight of fresh seed of M. oleifera was (9.351.68) g and its mean height, width and seed kernel rate were (26.121.80) mm, (28.61 1.55) mm and 70.43% 4.25%,respectively. There was a positive relationship between seed weight and fruit weight,and between seed kernel rate and single seed weight. The ranking of seed germination rate by direct seeding was shrub land > open forest land > grass land > bare land. The rankings of survival rate,total increments of plant height,total increments of basal diameter for two-year-old seedlings were open forest land > shrub land > grass land > bare land. According to our results, M. oleifera displayed better adaptability in shrub and open forest lands than in grass land and bare lands. Therefore, M. oleifera could be planted by direct seeding in shrub and open forest land rather than in grass land and bare lands in rocky desertification regions, southwest of Guangxi.
