Morphological and Radical Parameters Associated with the Seedlings Quality of Anadenanthera peregrina (L.) Speg.in Different Substrates. In this research, we evaluated the effects of different substrate formulations on the quality of angico-vermelho seedlings (Anadenanthera peregrina (L.) Speg). The tested substrates corresponded to eight different formulations: Bioplant®, Carolina Soil, Coffee husk, Coconut fiber and Vermiculite. In the nursery phase, the following were evaluated: height of the aerial part (H); neck diameter (D); fresh and dry biomass of the aerial parts and radical system; dickson quality index (IQD); number of roots regenerated in tubes; and length of roots regenerated in boxes. In the field phase, the following were evaluated: survival; crown diameter; number of lateral roots; and length of the pivoting root. To produce seedlings, a completely randomized design with eight treatments and four replications was used, and for the evaluation of the root regeneration potential (P.R.R.), six replications were used. In the field, the experimental arrangement consisted of subdivided plots, arranged in randomized blocks with four replications. Seedlings with higher averages for most of the evaluated characteristics were produced in the formulation of substrate containing 50% Bioplant® + 30% coffee husk + 20% coconut fiber. The values related to the IQD were positively related to the substrate formulations containing Bioplant®, coffee husk and coconut fiber, which were also positively associated with P.R.R. The substrate formulations containing Bioplant®, coffee husk and coconut fiber resulted in seedlings with a higher P.R.R., evaluated in boxes. Substrates containing Bioplant®, Carolina Soil, coffee husk and coconut fiberfavored the production of seedlings with a better radical system and, consequently, better in the field.

Azadirachta indica A. Juss. of the Meliácea family originates from India. It is considered important in Brazil due to its multiple uses. The plant is usually propagated by sexual reproduction (seeds), however, after harvest the seeds have to be sown as soon as possible because they lose germination viability very quickly. The use of juvenile propagules for A. indica seedlings propagation is a viable option, since there is a high demand in the semi arid regions due to wide use in urban afforestation. The objective of this research was to evaluate the effect of fertilization regimens and environments on obtaining Apical cuttings of juvenile origin and on the quality of cloned seedlings of Azadirachta indica. The research was carried out at the Forest Nursery of UFCG/Patos-PB, Brazil, with vegetative propagules (cuttings) obtained from three environments and two fertilization regimes: Biweekly and monthly, in addition to the control (without fertilization). The experiment was arranged in completely randomized design, factorial 3 x 3 (environments of origin of cuttings x fertilization regimes), with six replications, where each plot consisted of a cutting, totaling 54 experimental plots. Results indicated that propagation of Azadirachta indica through cuttings of juvenile origin is feasible, with an average rooting of 95.2%. It is recommended to use the monthly fertilization regimen, since in general it did not differ significantly from the biweekly regime. Fertilization provided better development and quality of the root system and aerial parts.

The quality of the seedling produced is directly related to substrate composition, so it is essential to select constituents with adequate characteristics. The objective of this study was to evaluate Eucalyptus urophylla, Peltophorum dubium and Eremanthus erythropappus seedlings and to relate the physical and chemical characteristics of the formulated substrates to their quality. For each species, an experiment was carried out in a completely randomized design (CRD), consisting of five treatments, five replicates, and plots composed of 20 seedlings. In order to evaluate the quality of the seedlings, the biometric variables were measured and, as a qualitative analysis, the ease to remove the seedlings from the tubes (ERT) and root aggregation to the substrate (AGGR) were evaluated. Seedlings produced in the substrates formulated with alternative constituents showed higher values when compared to seedlings produced with commercial substrate, for most of the analyzed variables. Coffee husk can be applied in the production of seedlings of P. dubium and E. urophylla. For the formation of E. erythropappus seedlings, none of the formulations tested are recommended.

Abstract The objective of this work was to evaluate the effect of different compositions of renewable substrates and seasons of the year on the quality of Piptocarpha angustifolia clonal plants. The experiment was carried out in a completely randomized design in a 4x6 factorial arrangement (four seasons x six substrate compositions). The analyzed substrates were: S1, commercial substrate with pine bark and coconut fiber base (CF); S2, carbonized rice husk (CRH); S3, fibrous and grainy CF; S4, 50% CF and 50% CRH; S5, 30% CF and 70% CRH; and S6, 70% CF and 30% CRH. Minicuttings of 8±1 cm were planted in tubes of 110 cm3 and placed in a greenhouse, during the four seasons of the year. The evaluated variables were: survival and number of roots at 70 days; survival and emission of shoots at 100 days; rooting, shoot height, stem diameter, and their ratios; easiness of removal from tubes; aggregation to the substrate; and multiplication rate at 130 days. The highest CRH/CF ratio favored the development of better-quality plants, and S5 was the most adequate substrate. Spring is more favorable to the survival and quality of cuttings, and, together with summer, favors the highest multiplication rates. The S5 substrate has better physical and chemical quality and improves P. angustifolia clonal plants.

ABSTRACT Brazil is the world’s largest producer of sugarcane (Saccharum officinarum L.) and research aimed at propagation has promoted higher quality in production. The objective of this study was to investigate the effect of the variation of micrometeorological elements on the survival and quality of pre-sprouted sugarcane plantlets. The study was carried out in a protected environment (UFRPE). Plantlets of the cultivar RB92579 were obtained by the technique of production of pre-sprouted plantlets. The protected environments were divided into four modules covered with low-density polyethylene plastic + photo-selective shade nets and one module without shade net. Micrometeorological data of global and photosynthetically active solar radiation, air temperature, substrate temperature, relative humidity and the solar radiation spectrum were recorded in each module. The experiment was conducted in a completely randomized design and the principal component analysis was used to verify the association between the cultivation modules, micrometeorological variables and crop variables. Anti-UV low-density polyethylene plastic + freshnet led to lower transmittance of global solar radiation, higher percentage of photosynthetically active radiation and lower plantlet mortality. Substrate temperature above 30.2 °C resulted in higher plantlet mortality. Larger spectrum in the red range led to the production of better quality plantlet. The use of freshnet shade net promoted adequate conditions for the cultivation of sugarcane plantlets and allows obtaining better quality plantlets.
