Seed positioning in extruded pellets

Count data of emergence / survival of Jacksonia furcellata (Grey stinkwood), a native Banksia woodland shrub. Seeds were either positioned precisely at 2 mm (top), 6 mm (middle) and 12 mm (bottom) within pellets (+/- AC) or left untreated (non-enhanced) and sown under the soil surface in the equivalent positions. In two controlled trials; 1) extruded pellets sown above the soil surface and 2) extruded pellets sown below the soil surface and trays were either treated with a pre-emergent herbicide (Simazine), or left unsprayed

本数据集记录了杰克逊氏木（Jacksonia furcellata，别名灰臭木Grey stinkwood）——一种原生班克木林地灌木——的出苗与存活计数数据。试验中，种子或被精准放置于丸粒（±AC）内的2 mm（上层）、6 mm（中层）与12 mm（下层）位置，或不做任何处理（非强化组），并在对应位置播于土表下方。本研究包含两项受控试验：1）将挤出型丸粒播于土表上方；2）将挤出型丸粒播于土表下方，且试验托盘分别施加芽前除草剂（西玛津Simazine）或不予喷施。
