| Summary: | Background: Some of the species that make up the legume family are used as animal feed and to improve soil fertility. However, their use is limited due to low seed availability and low germination rates.
Questions: Which scarification treatment is most effective in increasing germination? What is the response of plants to growth under field conditions?
Studied specie: Teramnus labialis (L.f.) Spreng.
Study site and date: Ciego de Ávila, Cuba, 2019 year.
Methods: Four scarification treatments (sanding, sulfuric acid, hot water, and liquid nitrogen (LN)) were evaluated under controlled laboratory and field conditions. Seed coat structures, imbibition capacity, electrolyte loss, and germination were studied under controlled laboratory conditions. Under field conditions, plant morphological traits were evaluated during the vegetative and reproductive phases.
Results: Scarification with LN caused multiple cracks in the seed coat, while sulfuric acid caused wear and detachment of the seed coat. With the use of LN, seed imbibition and germination were improved. In addition, 78 % of plants emerged with this treatment and crop establishment was achieved 120 days after sowing.
Conclusions: Scarification with LN of T. labialis seeds was the most effective treatment to improve germination and reduce the time to establishment of the species.
