Basil (Ocimum spp.) is an essential oil producing plant and it used as a condiment for diferent foods, besides serving raw material medicinal purposes. This crop has also been showing great importance ornamental in recent years. However, basil lacks studies concerning its different usages with special regards to potential. Therefore, this study aimed at evaluating the vegetative development potential of cultivars ‘Grecco Palla’ (O. minimum), ‘Alfavaca Basilicão Vermelho’ basilicum), ‘Thai...
Sweet potato [Ipomoea batatas (L.) Lam.] is a multipurpose plant due to the different uses for its roots, leaves, and branches.The objective of this study was evaluate ornamental potential sweet accessions from Germplasm Bank Embrapa Hortaliças, Brasilia, DF, Brazil.The morphological characterization evaluation used five with distinct leaf shape (CNPH 980, CNPH 1205, 895, 796, 1284) 12 qualitative quantitative descriptors [plant type (PT), lobe (LLT), immature color (ILC), number (LLN),...
RESUMO Os ácaros Oligonychus ilicis (McGregor, 1917) (Tetranychidae) e Brevipalpus phoenicis (Geijskes, 1939) (Tenuipalpidae) causam prejuízos econômicos ao cafeeiro seu controle é feito geralmente por meio do método químico. Dentre os inimigos naturais que regulam as densidades populacionais desses artrópodes-praga, destacam-se crisopídeos, quais devem ser preservados uso de compostos seletivos. Desta forma, objetivou-se avaliar efeitos espirodiclofeno (0,12 g i.a./L), fenpropatrina (0,15...
Molecular genetic variability studies are essential to complement the agronomic characterization of yellow passion fruit genotypes (Passiflora edulis Sims). Therefore, this study aimed at evaluating diversity 24 obtained from a research program developed by University Brasilia and Embrapa Cerrados, using RAPD molecular markers. markers were eight decamer primers converted into matrix binary data, which dissimilarities among estimated, clustering analysis was performed. A total 54 obtained,...
This work aimed at evaluating and comparing agronomic characteristics of 15 quinoa (Chenopodium Willd) genotypes cultivated in two altitudes sowing densities. The experiment initiated by individual plant selection Brasília, DF, followed progeny evaluation Colombia, 1,100 m 1,850 altitude population densities 30 12 plants m-1, with row spacing 0,50 m. Eleven progenies four commercial cultivars were tested. obtained selecting individuals BRS Syetetuba based on height, grain dry matter yield,...
The search for time and human subjectivity reduction in the analysis of physiologic potential seeds has brought forward use computerized systems as an alternative. goal this research was to assess effectiveness GroundEye equipment characterization soybean vigor by using image technique comparison information provided tests recommended seeds. Sixteen lots two varieties were used — variety 98Y12 P98Y70, characterized following tests: germination test, accelerated ageing cold tetrazolium...
