Abstract

Abstract: Thousand-seed weight (TSW) is used to calculate the sowing density, number of seeds present in a sample, and predict seed size. Our aim was to establish an alternative methodology for thousand-seed weight determination in forest species using image analysis techniques. The traditional methodology was compared with the alternative one, testing them on seeds from 16 forest species. The traditional method was performed by manually counting eight repetitions of 100 seeds, weighing of samples, and computation of thousand-seed weight. The alternative methodology was performed by counting seed samples captured by images and processing in ImageJ® software, followed by weighing a single sample, and computation. All steps were timed, and each methodology was repeated ten times per species. The TSW obtained by the alternative methodology was similar to that obtained by the traditional one, and the average execution time of the activities was reduced by 62%. The proposed thousand-seed weight determination by image analysis is an efficient and optimized alternative to the traditional method. Thousand-seed weight determination from image analysis reduces execution time for the seed analyst and forest seedling producer.
用图像分析法测定森林树种的千粒重
摘要:千粒重(TSW)用于计算播种密度、样本中存在的种子数,并预测种子大小。我们的目的是建立一种利用图像分析技术测定森林物种千粒重的替代方法。将传统方法与替代方法进行了比较,并在16种森林物种的种子上进行了测试。传统方法为100粒种子人工计数8次,称量样品,计算千粒重。另一种方法是对图像捕获的种子样本进行计数,并在ImageJ®软件中进行处理,然后对单个样本进行称重和计算。所有的步骤都是定时的,每种方法对每个物种重复10次。替代方法获得的TSW与传统方法相似,活动的平均执行时间减少了62%。本文提出的基于图像分析的千粒重测定方法是对传统方法的一种高效、优化的替代方法。从图像分析中确定千粒重减少了种子分析和森林幼苗生产者的执行时间。

期刊介绍: From 2017 the Journal of Seed Science (JSS) will circulate online version only. Original scientific studies and communications, not yet published or submitted to another journal for publication and written in Portuguese or English, will be accepted for publication. For manuscripts submitted in English, the authors should provide an adequated version. The SCIENTIFIC COMMUNICATION is a category of scientific manuscript which describes a technique, an equipment, new species or observations and surveys of limited results. It has the same scientific rigor as the “Scientific Articles” and the same value as a publication. The classification of a manuscript as a SCIENTIFIC COMMUNICATION is based on its content and scientific merit but it can be a preliminary study, simple and not definitive on a certain subject, with publication justified by its uniqueness and contribution to the area. The Editorial Board of the JSS may invite leading authors of recognized reputation to compose specific Review Articles covering topics of their specialization that will convey to the scientific community the state-of-the-art knowledge related to the specific theme.
