“…Regarding the height of seedlings, it is observed in Figure 5 that the best performances were obtained with the treatments T1 (sand), T2 (sand + coconut fiber) and T4 (sand + bovine manure) with averages 25.9; 26.2; 25.8 cm respectively, statistically correlating with treatment T3 (sand + rice husk), which showed an average of 24.9 cm, but differing from treatments T5 (sand + pine powder), T6 (sand + chicken manure) and T8 (sand + quail bed) in which they presented lower performances with averages of 22.5; 14.5 and 15.4 cm. In an emergency study with Campomanesia pubescens, Periotto and Gualtieri [22] using the substrate sand + coconut powder obtained shorter lengths in height. Guimarães, et al [23] evaluating substrates containing different organic residues and mineral fertilizers for the production of castor beans, concluded that the substrate composed of bovine manure provided the best growth of castor.…”

The Moringa oleifera Lam. it is a perennial, arboreal species, rapidly growing, resistant to drought and with leaves, flowers and edible fruits. With this research the objective to evaluate the effect of different substrates in the emergence and development of seedlings of Moringa. The experiment was carried out at the Plant Ecology Laboratory of the Department of Phytotechnics and Environmental Sciences, at the Center for Agricultural Sciences, at the Federal University of Paraíba. The experimental desing was completely randomized, with eight treatments T1= sand washed (control), T2= sand + coconut fiber, T3= sand + rice bark, T4= sand + bovine manure, T5= sand + pine powder, T6= sand + chicken manure, T7= sand + vegetable ash and T8= quail, with four repetitions of 25 seeds totaling 100 seeds for each treatment. The substrates were used in proportion 3:1, and these proportions were determined in terms of weight and all the sieved substrates, arranged in 6 cm x 29.5 cm x 45.5 cm trays, with an approximate capacity of 7 liters of substrate. The following parameters were evaluated: the emergence percentage, first count, emergence speed index, seedling height, plant height, root length, number of leaves, dry leaf biomass, stalk, root and total. The germination and initial development of M. oleífera seedlings were satisfactory in sand and favored when fibrous materials of vegetable origin (coconut fiber, rice bark or pine powder) or bovine manure were added to the substrate. The addition of manure sand from birds (chicken and quails) and vegetable ash did not favor the substrate for germination of Moringa oleifera Lam. seeds. Contribution/Originality: In search of alternatives to reduce costs and maintain the yield and quality of the production of Moringa oleifera Lam, we tested the use of alternative natural substrates. The influence of using different substrate alternatives on the nutritional quality of this crop is an economically viable and beneficial to the environment.Popularly known as moringa (Moringa oleifera Lam.), It is a species belonging to the Moringaceae family [1]. It is an arboreal vegetable that reaches 8 to 12 meters in height, has slight growth, the ability to resist in poor soils,

SEED, SEEDLING AND FRUIT MORPHOLOGY AND SEED GERMINATION OF Psidium sobralianum PLANTS OF THE SÃO FRANCISCO VALLEY, BRAZIL

et al. 2018

View full text Add to dashboard Cite

The Northeast region of Brazil has the second highest number of species of the Myrtaceae family. It is mostly covered by the Caatinga biome, which is very degraded, making it difficult to preserve species of this family. Thus, the objective of this work was to describe the seed, seedling, and fruit morphology, and seed germination of Psidium sobralianum Landrum & Proença plants of the São Francisco Valley, Brazil. The fruits were collected in an area of the Brazilian Agricultural Research Corporation (Embrapa Semiarid), in Petrolina PE, Brazil. The evaluations consisted of determinations of fruit shape, consistency, and number of seeds; seed form, cotyledons, hilum, hypocotyl-radicle axis, and embryo type; epicarp, mesocarp, endocarp, and seed staining; longitudinal, transversal, and ventral diameters of fruits and seeds; fruit, pulp, and seed fresh and dry masses; germination test; first count of germinated seeds; germination speed index; shoot and root lengths; shoot and root fresh and dry masses; and imbibition test. Psidium sobralianum has polyspermic, berry fruits, subclassified as solanidium, with persistent sepals and globular shape, consisting of epicarp, mesocarp, endocarp and seeds. The fruits have green with orange epicarp, pale-green mesocarp, and white endocarp. The seeds have a pilose and bony aspect, a pimentoid type of embryo, foliaceous cotyledons, presence of operculum and hilum, and pale-yellow tegument. The germination is epigeal phanerocotiledonar, with root protrusion from 26 days after sowing (DAS); it presents a short, glabrous, thick radicle, and a rounded, pale-green apex. The germination is slow, probably due to the mechanical barrier of the tegument, and stabilizes at 90 DAS.

Campomanesia guazumifolia (Cambess.) O. Berg. is a native fruit species, with ecological importance and potential to be exploited by food and medical industries. There is a lack of studies enabling its on-site conservation and propagation for commercial purposes. The objective of this work was to morphologically characterize the fruit, seed and seedling development stage of this species, as well as to determine an efficient protocol for the germination test, aiming at the commercial production of seedlings. Different temperatures (20, 25, 30 and 20-30 °C), substrates (blotting paper, sand and vermiculite) and light regimes (presence and absence) were tested in order to evaluate the germination power of seeds. Fruits are bacoid, rounded, with a fleshy pericarp and hairy surface, and with an intense yellow coloration. Seeds have a reniform shape and a lateral recess, with a membranous, brown and verrucose-glanulose tegument. It has a crass embryo, with a well developed hypocotyl-radicle axis and vestigial cotyledons. Seedlings are epigeal and phanerocotylar. It is recommended to conduct the germination test for the species with temperatures of 25 or 30 ºC, on paper substrates, with light presence or absence, and with the first test count performed 23 days and the final count 50 days after sowing.
