For terrestrial orchids, viability testing using tetrazolium (TTC) staining requires chemical scarification, as seeds have an impermeable testa. Different seed-coat permeability may affect TTC staining, thus affecting the results. The aim of this study was to perform a permeability test to assess the...

Tetrazolium test is also known as TZ test, is a reliable and widely used quick test for seed viability, introduced by the German scientist Lakon in 1942. It is based on topographic evaluation of a biochemical test which demonstrates that specific embryo structures have to be alive for the see...

The protected viability under accelerated ageing is attributed to the combined effects of zein, curcumin, and azadirachtin. The hydrophobic nature of zein, with its high prolamin content (over 70%), forms a moisture-resistant barrier over the seeds during storage. Additionally, the antioxidant prope...

Seed viability was evaluated with the tetrazolium test in four replicates of 10 pure seeds per species per harvest date. Seeds were placed in pill box trays and imbibed in 30 drops of 0.1% solution of 2,3,5-triphenyltetrazolium chloride, previously cut laterally to expose the embryo and facili...
DETERIORATION of seed during storage is a problem for plant breeders, seedsmen and farmers. Various methods have been proposed for testing the viability of crop seeds; these include testing enzyme activities1, the tetrazolium method2 and the X-ray contra
