VARIOUS APPLICATIONS FOR IMPROVING SEED QUALITY IN TRUE POTATO SEEDS
Project no. 32234 · Status: Kapanmış · 2024
Summary
<p>The aim of this study is to ensure homogeneous seed germination of heterogeneous and gradual emergence true potato seeds (TPS) by applying different chemicals, phytohormones and polymers. The thesis study was established according to the Completely Randomized Plot Design with 3 replications in 2024.</p><p>The laboratory trial was conducted at Ege University Seed Technology Application and Research Center (TOTEM). KNO3 (Potassium Nitrate), GA3 (Giberellic Acid), Chitosan, Urea, Polymer coating+KNO3, Polymer coating+GA3, Polymer coating+Chitosan, Polymer coating+Urea and Polymer coating+Pure water were applied to true potato seeds.</p><p>Seed counts were made and emergence was checked in accordance with the rules determined by ISTA (International Seed Testing Association). The data obtained were analyzed by variance analysis and the means were compared with the LSD test. As a result of the experiment conducted in the laboratory conditions; In applications of true potato seeds, the highest germination rate was obtained from applications containing polymer + GA3 (92%), GA3 (89%) and Polymer + Chitosan (84%). Applications of polymer + KNO3 (3.78 days), KNO3 (3.85 days) and GA3 (4.25 days) had the highest mean in terms of germination time in the study.</p><p>Keywords: True potato seed (TPS), GA3, KNO3, Urea, Chitosan, Polymer.</p>
