The purpose of this study was to determine the effects that different container conditions have on seedling growth. Under greenhouse cultivation, there were no statistical differences observed in plant height and the number of branches; however, significant differences in root collar diameter and root status were observed. In control container growth conditions, the roots grew in an abnormal spiral shape, while in negative phototropism container growth conditions the roots grew in a vertical shape. In outdoor cultivation, seedlings in various container growth conditions showed significant differences. The seedlings that were grown in negative phototropism container growth conditions showed the greatest increases in height, number of branches, root collar diameter, and root growth. This study determined that seedling roots in negative phototropism container growth conditions grew vertically, thus displaying successful rooting when they were transplanted outdoors. This resulted in favorable measurements in height, number of branches, root collar diameter, and root growth.
本研究旨在确定不同容器条件对幼苗生长的影响。在温室栽培条件下，株高和分枝数无统计学差异，但根颈直径和根系状况存在显著差异。在对照容器生长条件下，根系呈异常螺旋状生长，而在负向向光性容器生长条件下，根系呈垂直状生长。在户外栽培中，不同容器生长条件下的幼苗表现出显著差异。在负向向光性容器生长条件下生长的幼苗，其株高、分枝数、根颈直径和根系生长增加幅度最大。本研究表明，负向向光性容器生长条件下的幼苗根系垂直生长，因此在户外移栽时成功生根。这导致了在株高、分枝数、根颈直径和根系生长方面的有利测量。
