“…The substrates 2, 3, and 4 did not show a pH value within the range considered adequate for the development of seedlings (from 5.5 to 6.5), according to the classification described by Smiderle et al (2021a). The other tested substrates showed pH values adequate to those considered satisfactory.…”

The objective was to investigate the effect of substrate compositions with and without the addition of controlled release fertilizer (CRF) and to determine the correlations between the morphological characteristics of Agonandra brasiliensis. The variables studied were: shoot height, collet diameter, increase of height of shoot and collet diameter, shoot dry weight, root dry weight, total dry weight, the relation between the dry matter weight of the shoot and the dry matter weight of the roots, the relation between shoot height and collet diameter, the relation between shoot and root dry weight, and Dickson quality index. The results of the total dry weight of the ivory-wood plants allowed to infer a positive influence of the addition of CRF in the Sub 1 (8.3 g plant-1), Sub 2 (8.2 g plant-1), and Sub 4 (7.3 g plant-1) showing an increase of 72.2 %, 52.4 %, and 68.5 % respectively, when compared to Sub 1 (2.3 g plant-1), Sub 2 (3.9 g plant-1), and Sub 3 (2.3 g plant-1) without CRF addition. The substrates (sub 5) and (sub 1) with addition of CRF are indicated for the production of seedlings of Agonandra brasiliensis.

“…One of the main problems encountered in the formation of stands aiming at forest restoration is the quality of seedlings (Smiderle et al, 2021a). These, together with environmental factors and silvicultural techniques, are important for reducing costs and decreasing the time of settlement formation (Herrero et al, 2019).…”

“…This is why obtaining information on seed tolerance to drying relative to germination power is of great importance, since the germination test is the most-used official parameter to evaluate the physiological quality of seed batches (Souza et al, 2017;Menegatti et al, 2019;Smiderle et al, 2021). The above authors, however, attributed serious limitations to the germination test.…”

Eugenia stipitata is a fruit species from the Amazon that is important in traditional medicine due to its therapeutic properties. Estimates of seed viability in this species are still scarce, and it is necessary to develop rapid tests to determine the quality of the seeds. The aim of this study was to determine the applicability of the tetrazolium test to estimate viability and germination in seeds of E. stipitata with and without storage. The design was completely randomised in a 2 x 2 factorial scheme with 10 replications. The results of the tetrazolium and germination tests show that seeds of E. stipitata lose their viability when stored for six months in water at ambient temperature. Neither small nor large seeds stored for six months in water at ambient temperature are recommended for use with the tetrazolium test. Small, freshly harvested, unstored seeds show a germination potential of 100%. The tetrazolium test is efficient in determining the viability of small and large seeds of Eugenia stipitate with no storage.

Do stimulate® and acadian® promote increased growth and physiological indices of Hymenaea courbaril seedlings?

et al. 2022

Products that have biostimulant action on forest seedlings, such as those based seaweed Acadian® and hormones, have been used due to their beneficial effect on the physiology and growth of plants, in order to improve the quality of forest seedlings. The present study establishes as research problem: Can doses of Acadian® algae extract and Stimulate® be effective for the initial growth and physiological indices of jatobá seedlings? The variables evaluated were: shoot height (H), stem diameter (SD), increments in stem diameter (?SD) and shoot height (?H), shoot dry mass (SDM, g plant-1), root dry mass (RDM, g plant-1) and total dry mass (TDM, g plant-1), and Dickson quality index, net assimilation rate (EA, g.m-2.day), leaf relative growth rate (RA, g.m-2.day), leaf area ratio (FA, m2.g-1), specific leaf area (SA, cm2.g-1), leaf mass ratio (Fw, g/g-1) as well as nitrogen balance index (NBI) and chlorophylls. The plant growth regulators (Acadian®) at the dose of maximum technical efficiency of 0.28 ml L-1 promotes an increase in stem diameter in Hymenaea courbaril. Acadian® increases chlorophyll a and b contents in Hymenaea courbaril seedlings. The tested doses of Stimulate® do not increase chlorophyll a and b contents in H. courbaril seedlings.
