Osmopriming studies in bulb onion seed (Allium cepa L.)
This trial was divided in two steps: the first step was conducted in the College of Agriculture, National University of Colombia, where the osmopriming treatment of onion seeds was conducted. The second step was carried out at the Research Center of the Jorge Tadeo Lozano University. Eighteen treatments of osmopriming were proved, by using PEG (6000) and KH2P04 with bulb onion seed (Allium cepa L.). Solutions with three osmotic potentials -0.5, -1.0 and -1.5 MPa were used and seeds were embebed for 5, 10 and 15 days. A Completely Randomized design with a factorial arrangement of 2x3x3 was used. The experiment was replicated four times. The variables measured wereo: 1) Percentage of germination 5 and 10 days after imbibition, 2)Percentage of emergence at 12,17 and 21 days after seeding, 3) Root length, 4) Plant height, 5) Number of leaves, 6) Bulb diameter, 7) Fresh weight, and 8) Dry weight. Percentage of germination, percentaqe of emergence and root length were higher withKH2P04
