Initial Growth of Physalis peruviana L. Seedlings on Different Substrates

The substrate is one of the most important factors in the formation of the seedling and must present conditions suitable for germination and development of the seedling root system. The objective of this work was to evaluate the effect of different substrates on the initial growth of Physalis peruviana L. seedlings. The experiment was conducted at the Experimental Farm, of the Federal University of Espírito Santo– São Mateus (Brazil). The experimental design used was completely randomized, with three treatments (Soil, Provaso® and Bioplant®), seven replications and seven plants per plot, using seeds with 427 days of storage. At 56 days after sowing, the 10 most vigorous seedlings were selected for evaluation. The following characteristics were evaluated: percentage of emergence, emergence speed index (ESI), mean time of emergence (MET), number of leaves (NL), stem diameter (SD), aerial part length (APL), aerial part fresh matter (APFM), aerial part dry matter (APDM), root fresh matter (RFM), root dry matter (RDM) and Dickson quality index (DQI). The Provaso® substrate showed the best performance in all studied variables, being recommended for the production of Physalis seedlings.

ABSTRACT There is an increasing use of poultry litter in seedling production. However, studies regarding the effect of different particle-size litter on plant growth are still scarce. This study aimed to evaluate the growth of Moringa oleifera Lam. fertilized with poultry litter doses (0 g dm-3, 40 g dm-3, 80 g dm-3 and 120 g dm-3) with distinct particle sizes (1 mm and 4 mm), with four replications. The following variables were evaluated: plant height; root and stem diameter; leaf, stem, shoot and root dry matter mass; shoot/root dry matter mass ratio; and the Dickson quality index. There was no influence of the particle size on the studied variables, except for plant height. The root diameter decreased with the increase of the poultry litter doses. The accumulation of dry matter mass from the shoot and root increased with the increase of poultry litter doses up to 120 g dm-3. A linear increase of the Dickson quality index, relatively to days and poultry litter doses, was observed. It is recommended to apply 80 g dm-3 of poultry litter to fertilize M. oleifera plants, independently of the granulometry used.

ABSTRACT This study aimed to evaluate the growth and quality of seedlings of Plathymenia foliolosa Benth in response to base saturation of substrate and phosphate fertilization. The treatments were arranged in a factorial design of 6 P levels (0, 120, 240, 360, 480 and 600 mg dm-3) by 5 base saturation levels (3.5, 25, 40, 55, 70 %), in randomized blocks with four replications. The height of aerial part, neck diameter, shoot dry matter, root dry matter and total dry matter were determined at 118 days after the transplanting. It was still calculated the relation shoot dry matter/root dry matter and the Dickson Quality Index. There were significant effects of the phosphate fertilization for all studied variables. The base saturation had influence on all studied variables, except for the shoot dry matter/root dry matter relation. No significant effect of the interaction between base saturation of substrate and phosphate fertilization was observed on seedlings growth and quality. For the studied conditions, it is recommended 300 mg dm-3 of P for the production of quality seedlings of Plathymenia foliolosa without the necessity of liming.

Abstract The time of formation of mangosteen seedlings propagated by seeds can be considered as the biggest difficulty in the seedling production system of this species. Considering that the use of humic acids as a growth promoter has been well documented in some species, the objective of this work was to evaluate the growth of mangosteen seedlings in response to the application of humic acid (HA) doses extracted from vermicompost (0; 2; 20; 40; 200 mg C L-1). Growth rate was determined using the following variables: stem diameter, plant height, number of leaves, leaf area, stem dry matter, leaf dry matter, shoot dry matter, root dry matter, total dry matter and Dickson quality index . The dose 150 mg C L-1 was the one that approached the maximum values and therefore should be recommended for the production of seedlings. The results at 240 days after planting (DAP) showed that the HA increased the growth of mangosteen seedlings, helping to reduce the time of seedling formation under conditions for permanent planting.

The formation of quality forest seedlings has a direct relationship with the substrates that will be used; the germination of seeds and the formation of the root system and the aerial part are associated with the particular characteristics of each substrate. Therefore, the study aimed to evaluate the influence of different substrates on the formation of ipê-branco and ipê-amarelo seedlings. The experimental design adopted was completely random, with the treatments distributed in a 2 x 5 factorial arrangement (2 species and 5 substrates), with 4 replications. We used the following components to compose the substrates: carbonized rice husks (CAC), fresh rice husks (CA), autoclaved for two hours at 120 °C, commercial substrate (SC) Bioflora, washed sand (AL), and bovine manure (EB). The study was arranged in five treatments: treatment 1 - CAC, treatment 2 - CA, treatment 3 - SC, treatment 4 - AL and treatment 5 - EB. The following morphological characteristics have been evaluated: Collection diameter, height of the seedlings and the Dickson Quality Index (DQI) of the seedlings, which was obtained through the variables: weight of total dry matter (TWMW), weight of dry matter of the aerial part (TWMW), weight of dry matter of the root (RWMW), H and DC. The emergence speed and the emergence percentage index were lower for both species in the treatment containing 100% in natura rice husk. The commercial substrate Bioflora, enabled good performance in the emergence of both species, obtaining satisfactory results in terms of the percentage rate of emergence and a higher speed of emergence between treatments. The bovine manure substrate obtained superior results in the initial development for both Handroanthus serratifolius (Vahl) S.O.Grose and Handroanthus roseo-albus (Ridl.) Mattos.

One of the main stages in the production system of a crop is the production of quality seedlings since it influences the plants' final performance in the field and their production. The study aimed to evaluate different nutrient solutions in the production of Cambuci pepper seedlings. The design used was a complete randomized design, with six treatments corresponding to the nutrient solutions proposed for the pepper crop by Castellane and Araújo, Claudio Roberto, Hoagland, and Arnon, besides the commercial products Plenan® and Biobokashi®, and a control treatment without fertilization, with six replications. The final evaluation was carried out 45 days after sowing. The following variables were analyzed: stem diameter, plant height, leaf dry matter, shoot dry matter, the number of leaves, relative chlorophyll index ("Spad"), and Dickson quality index. The seedlings subjected to the applications of Claudio Roberto and Hoagland and Arnon solutions have the highest heights and number of leaves, the largest stem diameter, shoot dry matter, leaf area, and Dickson quality index with 2.60 and 2.51 mm, 0.54 and 0.62 g, 38.64 and 41.91 cm2, and 0.107; 0.097, respectively. The Hoagland and Arnon nutrient solution provided the best characteristics to produce Cambuci pepper seedlings.

ABSTRACT ‘Pitombeira’ does not have organized cultivation, thus requiring information related to the production of seedlings, particularly in relation to chemical fertilizer. In this context, an experiment was conducted in order to define the best dose of nitrogen (N), using urea as N source, to be applied in ‘pitombeira’ seedlings. The experimental design was complete randomized blocks with four replicates and ten plants per plot, testing five N doses (0, 400, 800, 1.600 and 3.200 mg dm-3). Data were submitted to analysis of variance and regression. The non-destructive measurements (number of leaves, stem diameter, shoot length and the ratio between shoot length and stem diameter) were evaluated at 30, 60, 90 and 120 days after transplanting (DAT). In addition, shoot, root and total dry matter and Dickson quality index were determined at 120 DAT. Nitrogen fertilizations, from the dose of 500 mg N dm-3 as top-dressing, were those that led to the most vigorous ‘pitombeira’ plants, while plants developed with dose above 1.600 mg of N dm-3 showed a reduction in their vigor.

Humic acids constitute a fraction of organic matter that either has direct effects on the growth and development of ornamental plants. The present study aimed to evaluate the differential growth of the leopard flower (Belamcanda chinensis) from the application of humic acids extracted from poultry litter (HAPL) and bovine manure (HABM) during the nursery garden phase. The seeds were immersed in solutions of 0, 10, 20, 30 and 40 mmol L-1 of C in HAPL and in the same way for HABM. After 150 days, the plants were collected and measured the number of leaves, plant height, fresh matter of the aerial part, dry matter of the root, total fresh matter, and dry matter of the aerial part, dry matter of the root and total dry matter. The use of the correct concentration of humic acids stimulates the growth and accumulation of total dry material in the leopard plant in the order of 33% to 58% for HAPL and HABM respectively.

This study aims to identify correlations between growth variables and the Dickson quality index in seedlings of Eucalyptus grandis and Pinus elliottii var. elliottii. The experiment was conducted in a greenhouse and the following variables were observed: stem base diameter, shoot height, number of leaves, leaf dry matter, stem base dry matter, root dry matter, shoot dry matter, total dry matter, ratio of shoot dry matter to root dry matter and ratio of shoot height to stem base diameter in E. grandis 60, 75, 90, 105 and 120 days after seedling emergence, and in P. elliottii 25, 50, 75, 100, 125, 150 and 175 days after seedling emergence. Using Pearson correlation and also path and regression analyses, correlations were analyzed between observed variables according to day after emergence and the Dickson quality index. Stem base diameter was found to have stronger correlation with days after emergence in comparison to shoot height, in both species. Root dry matter was found to have stronger correlation with the Dickson quality index. Stem base diameter was the most suitable parameter to indicate seedling quality due to its higher correlation level with the Dickson quality index. Shoot height was only effective to indicate seedling quality if analyzed together with stem base diameter. Variables relating to dry matter showed the highest correlations with the Dickson quality index (DQI), followed by stem base diameter. Conversely, number of leaves showed the poorest correlations with DQI, followed by seedling height.

The objective of this study was the selection of superior genotypes for growth traits, correlating them to initial height growth in the field, at age eight months. A random block design was used in the nursery, with eight clones, three replicates and four plants per plot. And a random block design was also used in the field, with eight clones, four replicate blocks and nine plants per plot. Data being analyzed in the nursery at age 120 days included: height of field seedling, at age eight months (Hc), height of nursery seedling (Hm), root collar diameter (Dc), shoot diameter (Db), shoot dry matter (PMSPA), root dry matter (PMSR), total dry matter (PMST), ratio of shoot dry matter to root dry matter (PMSPA/PMSR), Dickson quality index of root collar diameter (IQD-Dc), Dickson quality index of shoot diameter (IQD-Db). Analyses of variance showed that significant genetic differences exist among clones for all traits and, given the high heritability values found, the estimated genetic gains were generically very high. As for predicted indirect genetic gain, selection in nursery seedlings for Dc, PMSPA/PMSR, IQD-Dc provided the highest values of indirect gain in field seedling height.
