摘要: Sweet potato (Ipomoea batatas) plants produce adventitious roots that may swell to form localised carbohydrate storage structures as the growing season advances. These sections of root are known and part commonly harvested for human consumption. A is a morphologically defined segment an root, characterised by its distinctive lateral growth, which represents region marked meristematic activity deposition. The attached sweet plant at proximal end variable length relatively unthickened stalk. At distal continues extend, performing typical functions such absorption water minerals, anchorage. stalk generally considered cultivar-specific used formal morphological feature in cultivar descriptors. This study demonstrates be modified manipulating propagule interaction with environment. function occurs can moved down increasing end. useful developing plug-based propagation systems eliminate coiling initiated within physical constraints plug tray.
