Biometry, Emergence and Initial Growth of Accessions and Mangaba Progenies

Mangaba (Hancornia speciosa Gomes) is a native fruit of great economic, cultural, and environmental importance in its areas of occurrence. Due to extractive activities and real estate pressure, the number of natural populations has considerably decreased. The propagation of the species is still one of the primary obstacles for orchard implantations, thus, studies that provide a better understanding of the dynamics of the species’ growth should be developed. This work aimed to evaluate the biometry, emergence, and initial growth of mangaba progenies (Hancornia speciosa Gomes), using the plant material from the Active Germplasm Bank of Embrapa Coastal Tablelands, located in Itaporanga d’Ajuda, SE, Brazil. Treatments consisted of progenies from 17 accessions. The experiment was carried out in a completely randomized design with four replications of 25 seeds. Number of seeds per fruit, as well as fruit and seed weight (g), length (mm), width (mm), and thickness (mm) were evaluated. For emergence and initial growth, the following variables were analyzed: percentage of emergence (PE%), emergence speed index (ESI%), survival rate (SR%), height (H), stem diameter (SD), and the number of leaves (NL). Biometric analyses of fruits and seeds revealed significant phenotypic variability among mangaba accessions. Progenies of the accessions LGP1, LGP3, LGP4, PTP4, TCP2, TCP6, ABP1, ABP2, ABP4 and BIP4 showed better results for all emergence and initial growth variables. The progenies of accessions TCP1, BIP4, CAP5 and PRP5 expressed lower emergence and survival percentages, and low vigor.

The application of Trichoderma fungus can be used to obtain seedlings of higher quality for plantations. The objective of this study was to evaluate the effects of Trichoderma isolates on the germination and initial growth of açaí seedlings. Two trials were set up. In the laboratory, the seeds were inoculated in suspensions prepared with each of the isolates for 24 h, and they were arranged in trays containing filter paper in a completely randomized design with five replicates containing 50 seeds each. For the control, the seeds were submerged only in water. Part of the seedlings resulting from seeds treated and not treated with Trichoderma were transferred to bags containing forest soil and were submitted to seven modes of application of Trichoderma and kept in a nursery. The speed of germination and hypocotyl were not influenced by the biological treatment. The application of the different Trichoderma isolates positively influenced the height, collar diameter, number of leaves, root size, leaf area and root, and aerial part dry mass of the açaí seedlings. The application of the Trichoderma isolate TAM01 on the preplanting substrate and biweekly applications on the postplanting substrate was the combination that most positively influenced the development of açai seedlings.

The objective of the current study was to measure the genetic variability of natural populations of Hancornia speciosa using RAPD type molecular markers to assay variation in existing sampled genotypes, using morphological variables, and so assess germplasm bank composition. Morphological and chemical characteristics H. speciosa fruits and seeds were evaluated using descriptive statistics and principal components analysis. Cluster analyzes was conducted using Jaccard's similarity index, via the UPGMA hierarchical agglomerative method. Phenotypic variability was found in the two studied populations. However, variability was higher in the São Judas population, where the variables: pulp yield and soluble solids content were higher than those in the Canaã population. High genetic variability was found in both study populations, and between- and within-population morphological and genetic variation was present in the studied populations. The nine primers generated 70 bands, of which 68 were polymorphic, with the primers A-08 and C-04 generating the highest number of polymorphic bands. The two populations differ principally in the pulp ratio and the proportion of total solids in the pulp (°Brix). RAPD markers used gave acceptable results and, to initiate the Federal University of Tocantins Active Mangaba Germplasm Bank, seven genotypes were sampled from the Canaã population and five from the São Judas Tadeu population.

ABSTRACT: The objective of the current study was to assay the germination behavior of seeds from fruits collected from three natural populations of H. speciosa, located in remnant areas of Cerrado in the municipality of Porto Nacional, Tocantins state, Brazil. The studied populations were: Canaã, São Judas Tadeu and Providência. Seven genotypes were selected from each population and twenty fruits of each genotype were collected. After ripening, the fruits were manually pulped and seeds of the same genotype pooled. After cleaning, removing adhered pulp and exterior sterilization, seeds were sown in a nursery. The experimental used a Completely Randomized Design (CRD) with three replications. Four seeds of each genotype were sown per polyethylene bag and the germination monitored until the 45th day after sowing. Variables used to assay germination behavior were: Germination (G,%); Mean Time of Germination (MTG, days); Average Speed of Germination (ASG, d-1), Germination Time Variation Coefficient (VCt) and Germination Synchrony Index (Z). For germination data, nonparametric Kruskal-Wallis analysis of variance was performed, followed by Dunn's test at 5% probability. There was a difference between populations for all germination variables, with the Providência population performing the best. The variables MTG, ASG and Z were significantly higher for the Providencia population. In absolute terms, the Providencia population had the highest percentage of germination (G), but did not differ significantly from the São Judas Tadeu population. The results generated are important for understanding the germination of seeds of different populations of H. speciosa. This information is relevant for the ex situ spread of the species.

The aim of this study was to prove that Arabica coffee introgressed with C. liberica, have resistance to Meloidogyne paranaensis (Mp). Open pollinated fruits were harvested from mother plants of 29 Arabica coffee genotypes from the IAPAR germplasm bank. Seeds were collected from the fruits and were sown to obtain seedlings to test the resistance to Mp. The experiment was set up in a completely randomized design with 29 coffee genotypes, 8 replications, and one plant per plot. Cultivars Catuaí Vermelho IAC 99 and IPR 100 were used as susceptible and resistant checks, respectively. Seedlings with three to four pairs of leaves were inoculated with 1,400 eggs and juveniles J2 of Mp (IP). At 120 days after inoculation, seedlings were evaluated by counting the nematodes per gram of roots, and the final nematodes population was obtained (FP). The reproduction factor (RF) was calculated using the formula: RF = FP/IP. The reproduction factor reduction was used to classify the resistance levels of genotypes, which were classified as highly resistant (HR), resistant (R), moderately resistant (MR), moderately susceptible (MS), susceptible (S) an highly susceptible (HS). All genotypes differed from Catuaí in resistance factor (RF), five of which did not differ from IPR 100 for RF, and only the line IAPAR 15242 had RF < 1.0. Out of 28 Arabica genotypes introgressed with C. liberica, five HR, 11 R, 11 MR and one MS were identified. However, only IAPAR 15242 and IPR 100 were classified as HR and presented 100% of HR plants, but only the first showed an RF < 1.0. Results revealed that these Arabica coffee genotypes with introgression of C. liberica genes have great potential to be used in breeding programs and they are a new alternative as a source of resistance.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.
