Abstract

ABSTRACT Canola, which has tiny oil-producing seeds, requires care during planting, so that there is an ideal number of plants. The aim of this study is to evaluate alternative method of sowing using adhesive tape and the influence it has on the emergence and vigor of the seedlings of different canola hybrids and define the best positioning of the adhesive tape for the formation of the experimental field. The study was carried out at the Seed Laboratory at the Universidade Federal de Goias. The tests were conducted with hybrid canola seeds (Hyola: 50, 61, 433, 571CL and 575CL). The seed characterization was performed in terms of physiological quality. They were then sown: without adhesive tape; seeds arranged on adhesive tape with the tape facing down, sideways and up, with a completely randomized experimental design, in a 5x4 factorial scheme. The evaluations were performed: emergence, speed of emergence index and first seedling emergence count in sand. The use of the adhesive tape did not interfere in the emergence of canola hybrids seedlings, with the Hyola 571CL characterized as having the best performance while the Hyola 50 and 61 had inferior performances.

Highlights

Canola (Brassica napus L. var oleifera) is an oilseed belonging to the Brassicaceae family, developed by Canadians while genetically improving the conventional rapeseed (Tomm et al, 2009b)
The objective of this study is to evaluate the alternative adhesive tape method for sowing and its influence on the emergence and vigor of seedlings of different canola hybrids and to define the best positioning of the adhesive tape for the formation of the experimental field
We can highlight the hybrid canola seeds (Hyola) 571CL hybrid that, even with a lower mass, obtained the best germination (99%) and vigor results evaluated by the first germination test (96%), electrical conductivity (94.2 μScm-1g-1) and accelerated aging (77%), and is referred to as the hybrid with seeds with a higher physiological potential

Summary

Introduction

Canola (Brassica napus L. var oleifera) is an oilseed belonging to the Brassicaceae family, developed by Canadians while genetically improving the conventional rapeseed (Tomm et al, 2009b). In the last 40 years its production has grown rapidly worldwide, from the sixth most-produced oilseed in the world to the second (USDA, 2017). It has been used in Europe since the 13th century for food purposes, and the processed oil contains an adequate ratio of erucic acid as well as a balance between essential omega fatty acids 3-6-9 (Süzer, 2015). In the South of Brazil, canola is planted as a winter crop, much like safrinha (a second crop) in the CenterWest of the country (Tomm, 2006; Melgarejo Arruá et al, 2014), guaranteeing its place as part of the crop rotation system that exists in Brazilian agriculture. Canola is cultivated in different types of soil, from sandy-loam to silty-clay, and this is a main reason for its good performance and profitability (Süzer, 2015)
