🌱 How to control Poa annua without resorting to herbicides? Researchers evaluated the use of Prohexadion-Ca (Regalis®) and growth-promoting microorganisms (Rhizoflo Premium®) as sustainable alternatives in the management of annual bluegrass, a common w**d in sports and ornamental lawns. Regalis® significantly reduced the presence of Poa annua and the overall growth of grasses, while Rhizoflo Premium® favored the development of the lawn without directly affecting the w**d. The combination of these strategies, combined with seasonal heat stress, has proven effective in integrated management practices, reducing the dependence on herbicides and promoting healthier lawns.

🌿 Nepenthes spp. (carnivorous plants) is an ornamental genus with modified leaves to capture prey.

🔎 This study developed SSR markers to evaluate the genetic diversity of nine species native to Nepenthes in southern Thailand.

🪴 SSR markers revealed variability between species, being useful for studies of genetic diversity, parental selection in breeding programs and conservation of threatened species.

🌿 Portulaca oleracea L., known as beldroega, is a plant with multiple uses - ornamental, medicinal, food and phytoremedial.

🔎 Researchers sought to identify the best pot size to promote healthy and sustainable growth of the species in a protected environment. The study evaluated three sizes of vessels, being analyzed height, crown diameter and number of leaves.

🪴 For the rational and commercial cultivation of the belly, medium pots offer excellent cost-benefit.

hold genetic secrets that could transform ornamental breeding! In a study published in Ornamental Horticulture, researchers analyzed the DNA of diploid and tetraploid varieties of Adenium obesum and A. arabicum using flow cytometry, karyotyping, and FISH. The results indicate significant genomic differences, suggesting that they are not varieties of the same species — a discovery with a direct impact on taxonomy and genetic breeding. 🔗 DOI: https://doi.org/10.1590/2447-536X.v31.e312810 🔗 Download article: https://ornamentalhorticulture.com.br/rbho/article/view/2810/2076
