Teramnus labialis (L.f.) Spreng is a forage legume that is used for animal feed and as a cover crop in various fruit species. However, the seeds have a low germination percentage and after the emergence of the seedling establishment is difficult due to their slow growth. Seed priming treatments are an alternative to improve germination and vigor of...
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 conditi...

High rates of gastrointestinal parasite infestation lead to the frequent use of anthelmintics for their control, resulting in resistance in the main species of gastrointestinal nematodes. Natural plant extracts, particularly those from Azadirachta indica A. Juss leaves, have been described as having antiparasitic, antimicrobial, insecticidal, antio...
Legume seeds are rich in protein, making them useful in various biotechnological processes, such as protein hydrolysates, with different uses based on biological activity. These bioproducts can be used as agricultural biostimulants due to their ability to improve nutrient absorption and assimilation processes, biotic and abiotic stress tolerance, a...
BACKGROUND: N. wightii (Leguminosae) is valued as a cover crop and as a potential source of protein in food insecure countries. However, plantlet establishment is limited by physical dormancy. Our previous work has shown that exposure of N. wightii seeds to cryogenic temperatures is able to overcome physical dormancy. OBJECTIVE: The current study i...
Euphorbia heterophylla Linn. (Wild poinsettia), commonly considered an important weed in soybean, bean and corn crops, among others, is a plant that is still being investigated how to control it. 8-10 It is a plant with highly variable morphology and one of the most invasive weed species, especially in tropical and subtropical regions of the Americ...
The main route of propagation of forage legumes is through botanical seeds, so
knowing the necessary requirements (temperature and light) during germination is
essential to guarantee high germination percentages in the seeds of these species.
The objective of this research is to determine the temperature and light requirements (photoperiods) necess...
Teramnus labialis (L.f.) Spreng shows dormancy as a result of impermeability of the seed coat, which requires scarification treatment before sowing. Liquid nitrogen (LN) as a scarifying treatment has recently been used on this species, with excellent results. However, moisture content and immersion time on LN are factors that may affect seed germin...

Background:
Teramnus labialis (L.f.) Spreng is a potentially important legume species, and can be used as an animal feed and to enhance soil physicochemical characteristics. Despite the biological and agricultural importance, the low availability of seeds, their small size and the low percentage germination limit their large-scale use by farmers....
Introduction: The hard seed is the main cause of dormancy in most of the Leguminoseae species. Seed scarification methods, where physical damage is sought to break hard seed coat without diminishing quality, have been modified over time to make them more effective. The most commonly used seed scarification methods include heat, mechanical scarifica...
