小薯专用品种‘华薯16号’的结薯特性

Tuber Formation Characteristics of Special Small Potato Variety 'Huashu 16'

摘要

‘华薯16号’是小薯专用品种，具有小薯率高、食味优等诸多优良特性，明确其结薯特性有利于提高‘华薯16号’产量和品质。小薯品种‘华薯16号’和常规品种‘华薯1号’为试验材料，重点观测单株块茎数、主茎数、单株块茎鲜重等指标动态变化。相比‘华薯1号’，小薯品种‘华薯16号’干物质积累延后，植株更繁茂；整个生育期内‘华薯1号’和‘华薯16号’单株平均结薯数分别为5个和18个，‘华薯16号’单株结薯数较多原因是其具有较多主茎数。‘华薯16号’生育期长，为提高小薯率可适当提前收获。

Abstract

'Huashu 16' is a specialized variety for small potato production with many excellent characteristics such as a high small potato yield and good taste. Clarifying its tubering characteristics is beneficial for further improving the yield and quality of 'Huashu 16' in production. In this study, both 'Huashu 16', and 'Huashu 1', a conventional variety, were used as test materials, and the dynamic changes of indicators such as number of tubers per plant, number of main stems, and fresh weight of tubers per plant were closely observed. In comparison to 'Huashu 1', the small potato variety 'Huashu 16' had delayed dry matter accumulation and stronger plant vigor. On average, there were five tubers per plant for 'Huashu 1' and 18 tubers per plant for 'Huashu 16' throughout the entire reproductive period. The reason for the higher tubers per plant in 'Huashu 16' lied in more main stems. Additionally, 'Huashu 16' had longer growth period, and to increase the small potato yield, early harvesting is recommended.
