Soil strength x seed size interaction on emergence of long and short hypocotyl varieties

Days to emergence, cotyledon width & length, root length and shoot dry weight, emergence success and seed size data for long and short hypocotyl canola varieties in different soil types and soil strengths. \nLineage: Data were produced from experiments using the tube-based phenotyping system developed by Laura Goward, AJE Haddis, Greg Rebetzke and John Kirkegaard in the CSIRO/GRDC projects CSP2212-005RTX and CSP2212-007RTX. The purpose was to simulate field conditions (soil type, soil moisture, bulk density, sowing depth) under highly controlled temperature conditions to test the roles and interactions among seed, soil and environmental factors contributing to seedling emergence. In this project, we conducted two experimental runs focused on the roles of soil type (Geraldton sand; Wagga Wagga loam), soil strength (2.0 kg/cm2 [loose], 3.5 kg/cm2 [intermediate] and 5.0 kg/cm2 [restrictive]), seed size (2.6-3.1mg [small] and 4.8-5.3mg [large]) and hypocotyl length genetics (Reston and SlovenskaKrajova [long hypocotyls], Zircon [short hypocotyls] on seedling emergence success and time to emergence. \n\nIn Run1, all factors were included and with three replicates (108 tubes in total). Based on results from Run1, for Run2 we increased replication to nine reps (for loam treatments) or six reps (for sand treatments) and removed variety SlovenskaKrajova and the most restrictive soil strength (5.0 kg/cm2) (120 tubes in total).\n不同土壤类型与土壤紧实度下长、短下胚轴油菜品种的出苗天数、子叶宽长、根长、地上部干重、出苗成功率及种子大小相关数据。 数据集溯源：本数据集源于Laura Goward、AJE Haddis、Greg Rebetzke与John Kirkegaard基于澳大利亚联邦科学与工业研究组织/澳大利亚谷物研究与开发公司（CSIRO/GRDC）项目CSP2212-005RTX及CSP2212-007RTX开发的管状表型系统开展的试验。本试验旨在高度可控的温度条件下模拟田间环境（包括土壤类型、土壤含水量、容重与播种深度），探究影响幼苗出苗的种子、土壤及环境因子间的作用与交互关系。 本项目共开展两轮试验，重点探究土壤类型（杰拉尔顿砂土、瓦格瓦格壤土）、土壤紧实度（2.0 kg/cm²[疏松]、3.5 kg/cm²[中等]与5.0 kg/cm²[紧实胁迫]）、种子大小（2.6~3.1mg[小型]与4.8~5.3mg[大型]）以及下胚轴长度遗传特性（长下胚轴品种Reston、SlovenskaKrajova，短下胚轴品种Zircon）对幼苗出苗成功率与出苗时间的影响。 第一轮试验涵盖所有因子，设置3次生物学重复，总计108个培养管。基于第一轮试验结果，第二轮试验调整了重复次数：壤土处理组设9次重复，砂土处理组设6次重复，并移除了SlovenskaKrajova品种与最高紧实度处理（5.0 kg/cm²），总计120个培养管。
