| The objective of this experiment was to create identical seed by coating with fluorescent compounds. The experiment was conducted at Seed Technology Section of Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. The coating formulations were prepared using 1.5 % Hydroxypropyl Methylcellulose (HPMC) of fluorescent Rhodamine-B at the rates of 0.2, 0.4, 0.6, and 0.8 gram.The tomato seeds were coated by Centri Seed Coater (Model SKK 10). Coated seeds were subsequently divided into two parts. The first part; was used to detect fluorescence performance by hand-UV (Model UVGL-58; λ=365 nm.). The second part was used to evaluate the seed quality after coating and after accelerated aging with 100% relative humidity at 42oC for 74hours. It was found... |
