In the nursery, two experiments on the production of L. tuyrana seedling were evaluated. In the first experiment, three container volumes and the absence or presence (3 g L -1 ) of a controlled-release fertilizer (CRF) were evaluated. The use of tube trays (700 cm 3 ) and CRF significantly increased the height, biomass, and Dickson quality index of the seedlings (between 28 to 61 %) compared to those not fertilized. In the second experiment the light acclimation of seedlings was evaluated in two environments: full sun at 50% and 100%. There were no changes in photosynthetic rates when the seedlings were kept in the shade for longer, but there was a lesser accumulation of biomass. A light intensity of approximately 1 600 µmol m -2 s -1 is considered optimal for L . tuyrana seedling.","PeriodicalId":46895,"journal":{"name":"Floresta e Ambiente","volume":"140 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80546525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated germination performance and reserve mobilization in Dalbergia spruceana Benth. seeds incubation at 20, 25, 30, 35, and 40°C. The germination process was favored by incubation at 25 to 35°C and negatively affected at 20 and 40°C. At 35°C there reduction in germination speed, however, without significantly compromising the final germination percentage. The results showed that lipids and proteins are the predominant metabolites in D. spruceana seeds. Mobilization of soluble sugars was highest at 25 and 30°C. At 20 and 40°C, mobilization occurred more slowly, negatively affecting germination. This finding, combined with changes in lipid and protein reserves, suggests that lipid and protein hydrolysis products were used for starch synthesis. Reserve mobilization patterns in D. spruceana embryos were influenced by germination temperature, with the highest utilization efficiency occurring between 25 and 35°C.","PeriodicalId":46895,"journal":{"name":"Floresta e Ambiente","volume":"46 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83065357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
