“…Other studies have shown that the environment could also affect morphometric evaluation. Hydric stress seems to affect the seedling leaf area [13], and light exposure could also influence some seedling measurements, such as the collar diameter [20]. Hence, it is possible that studies using different conditions could also find variations in the results mentioned here.…”

“…In the literature, it is also possible to find the opposite scenario, in which the given information is consistent with population I but not to population II when the study data is compared to the mean values we found. For instance, the mentioned by Costa et al [20], in which the seedling collar diameter raged from 4.9 to 5.07 mm.…”

“…Morphological characterization and influence on seed and fruit quality have been scarcely explored to forestry seeds [9]. In this context, H. courbaril has the potential for quick production and high seedling survival in the field [11], [20]. These features favor faster seedling production and establishment in the field, which also promotes the regular use of this species in forestry and afforestation programs [20].…”

Morphological integrations are unknown to forestry seeds. Understanding if seed measurements could predict its future seedlings features is a central question in seedling production. Hymenaea courbaril is an important species in this context and to the applied forestry.Thus, this study aimed to understand how some seedling features, could be related to the seed weight, and be affected by the population origin. The measurements consisted of seedling collar diameter, weight, protophilus area, central and lateral vein. Seed weight consistently varied between the populations in the study. Both populations had higher weight ranges than mentioned in the literature. There was no strong evidence that greater seed weight requires lesser time to germinate, conflicting with previous information. All the measurements presented enough shreds of evidence to be considered different when comparing the populations, except for the protophilus area and lateral vein length. All the studied measurements presented low correlation indexes to seed weight, except for seedling collar diameter, and seedling weight, which presented a moderate correlation. Protophilus elongation pattern was strongly associated with the leaf width when compared to midvein.

“…In order to promote germination, in the commercial seedling production context, there are two main processes, open-field germination, where seeds are directly exposed to environmental conditions such as sunlight and temperature, or germination in a greenhouse, where seeds are exposed to greater temperature and moisture but less sunlight than the production area [21], [22]. These different techniques could also impact seed germination and seedling persistence [23], and aspects that have not yet been explored to E. edulis.…”

ABSTRACTEuterpe edulis is an endangered species with high importance ecologically and economically. Seedling production seems to be one of the most important alternatives to population recovery. Besides that, the knowledge of seedling production methods’ influence over germination is very restricted. Thus, this study aimed to evaluate the effects of parent populations, germination conditions, and the substrate to commercial seedling production of E. edulis. Nine thousand seven hundred and thirteen seeds were distributed between the heated water and control, greenhouse and open-field treatments. The parent population presented high differences between most of the germination indexes. Influencing the germination rate, mean germination time and germination speed, but not affecting synchrony and uncertainty indexes. Heated water treatment did not affect any of the studied indexes, presenting a close pattern of germination over time, indicating it is an appropriate method for seedling production. Greenhouse and open-field treatment presented variations at the same indexes affected in the parent population analysis. The most profitable method for E. edulis seed germination was the greenhouse production method, which provided the best indexes results.

Jatobazeiro seedlings associated with arbuscular mycorrhizal fungi

The symbiotic association between native fruit species with Arbuscular Mycorrhizal fungi (AMFs) can contribute to the growth and quality of seedlings in soils with low nutrient availability. Thus, the objective of this study was to evaluate the effects of inoculation with AMFs and phosphate fertilization on the growth and quality of jatobazeiro seedlings ( LHymenaea courbaril.). The experiment was conducted in a completely randomized design in a 5 x 5 factorial scheme. The treatments were constituted by inoculation with the AMFs: Clareoideoglomus etunicatum, Rhizoglomus heterosporum, Rhizoglomus clarum, MIX (mixture of inoculations) and without inoculation with the AMFs, associated with five P doses: 0, 60, 120, 180 and 240 mg kg-1, with growth evaluation at 30, 60, 90, 120 and 150 days after transplantation (DAT). At 150 DAT, the production of biomass, the quality of seedlings, the chlorophyll index, the dependence and mycorrhizal efficiency were determined. Phosphorus did not contribute to the jatobazeiro seedlings growth in the conditions of this study. Seedlings with R. clarum and MIX had the highest growth at 150 DAT, while seedlings with R. clarum also resulted in a greater biomass accumulation. The mycorrhizal dependence and efficiency was affected by phosphate fertilization, evidencing that jatobazeiro is a kind of optional mycorrhizal association.
