Cacti may look slow-growing, but they’re actually among the fastest-evolving plants on Earth 🌵. Researchers from @UniofReading found that what drives new cactus species isn’t flower size, but how quickly cactus flowers change shape over time. @ISTAseedtesting learns more: sciencedaily.com/releases/20… #seedquality #seedtesting

New research from @AarhusUni highlights how excess nitrogen pollution can weaken this balance, with impacts on forest health and resilience. Too much nitrogen pollution can: 🦠 Change soil microbes 🌱 Weaken roots 💨 Disrupt carbon flows ⚠️ Push ecosystems toward tipping points A reminder that even nutrients can become pollutants when there's too much of them. @ISTAseedtesting reads more: dca.au.dk/en/current-news/ne… #seedquality #seedtesting

📢¡Alerta de webinar! Dirigido a profesionales de habla hispana e interesados en el análisis de tetrazolio para especies forestales. 🌳Este webinar ofrece una visión general del @ISTAseedtesting Comité Técnico de Tetrazolio (TEZ) y de las actividades relacionadas con especies forestales que desarrolla este comité. Además, proporciona una introducción clara a la teoría y la práctica de los ensayos de viabilidad con sales de tetrazolio, una metodología ampliamente utilizada para evaluar la viabilidad de semillas forestales, especialmente aquellas recolectadas hace varios años. 📅14 de julio | 17:00 CEST 🌍Abierto a todo público 🔗Regístrate aquí: attendee.gotowebinar.com/reg… #seedquality #seedtesting #calidaddesemillas #análisisdesemillas #ISTAwebinar
