Abstract

ABSTRACT Planting sweet potato branches with the appropriate bud number and disposition, below and above ground, can favor vegetative growth and yield that better fit the marketable standards. This study aimed to explore the influence of the number of buds and their distribution ratio, above and below ground level, on the agronomic and marketable components of sweet potato tuberous roots. The experiment was carried out in a randomized complete block design with three replications. The treatments were arranged in a factorial scheme (3 x 5), with 2, 4, and 8 above-ground buds combined with 2, 4, 6, 8, and 10 below-ground buds. Branches from the UZBD 06 accession (Canadense standard) were used. Vegetative, productive, and marketable traits of roots were evaluated. The use of branches with a greater number of buds above and below ground increased shoot dry biomass. Planting seed branches with 8 buds above and 8 buds below ground provided a greater number and production of marketable roots. The use of 10 buried buds increased root number and yield in the 150-450 g marketable classes, which the consumer market values the most.

甘薯种子分枝芽数与产量的关系

在地上和地下种植适当芽数和芽位的甘薯枝条，有利于营养生长和产量，更符合市场标准。本研究旨在探讨地上、地下芽数及其分布比例对甘薯块根农艺成分和商品成分的影响。试验采用完全随机区组设计，设3个重复。按阶乘方案(3 × 5)安排处理，地上芽2、4和8个，地下芽2、4、6、8和10个。从uzbd06加入(加拿大标准)的分支被使用。对根系的营养、生产和销售性状进行了评价。利用地上和地下芽数较多的枝条可增加地上部干生物量。种植地上8芽、地下8芽的种子枝可以提供更多的可销售根的数量和产量。在150-450克的可销售品种中，使用10个埋芽可以增加根数和产量，这是消费市场最看重的。
