Influence of Nitric oxide donor nanoencapsulation on Dyckia excelsa Lema (Bromeliaceae) germination

Bromeliads are used in landscaping due to the beauty of their leaves and flowers. The use plant regulators such as nitric oxide (NO) promotes stimulus germination it has been a way out enhance production reduce search for plants nature nanoencapsulation aims optimize its effect. objective this work was evaluate effect using free nanoencapsulated NO donor on D. excelsa. treatments consisted soaking seeds 5 minutes with s-nitrosoglutathione (GSNO), chitosan/sodium tripolyphosphate nanoparticles containing GSNO (NP CS/TPP-GSNO) empty CS/TPP) at doses: 15 mM 20 mM. control imbibition distilled water. For each treatment, 4 replications 50 were used. following variables evaluated: percentage (GER), first count (FGC), speed index (GSI), average time (AGT) addition length (SL) seedling dry weight (SDW). To characterize seeds, water content viability evaluated. excelsa had 9.9% 64% viability. GER, ranged from 43 60%. application stimulated process did not cause any difference results compared GSNO. It concluded that or is recommended stored
