本文研究了漫射太阳辐射(DSR)、降水和气温对油菜幼苗存活和死亡的影响。2010年4月至2011年1月期间，在位于巴西帕拉帕拉贝勒姆孔布岛环境保护区的河口洪泛区森林中对这些数据进行了评估。在Combu岛的下层安装了一个自动气象站，以收集这些元素，其位置是考虑到acai树苗的绝对数量和通过太阳能电池板上树冠太阳斑的漫射辐射而确定的。共划定了6块2m×20m的地块，从北、南、东、西四个方向随机分为10块2m×2m的小块，另外两块随机分成两块。对高度在10厘米到2米之间的苗木进行量化，并每两周监测一次存活率和死亡率。数据采用皮尔逊相关系数进行统计分析。最初，记录了1072个个体，其中...
AbstractThe effects of diffuse solar radiation (DSR), precipitation, and air temperature on survival and mortality of seedlings of acai (Euterpe oleracea Mart.) were evaluated in an estuarine floodplain forest located in the environmental protection area of Combu Island, Belem, Para, Brazil, in the period from April 2010 to January 2011. An automatic weather station was installed in the understory of Combu Island to collect from the elements, whose location was defined by taking into account the sheer number of seedlings of acai and the incidence of diffuse radiation through canopy sunflecks on the solar panel. Six plots of 2 m × 20 m were demarcated and divided into 10 subplots of 2 m × 2 m in the directions of north, south, east, and west and two others at random around the station. The seedlings with a height between 10 cm and 2 m were quantified and monitored biweekly for survival and mortality. Data were statistically analyzed by a Pearson correlation. Initially, 1072 individuals were recorded, with ...
