title: Diallel analysis of “dedo-de-moça” pepper seeds in relation to physiological potential

description: ABSTRACT “Dedo-de-moça” (Capsicum baccatum var. pendulum) is one of the main chili peppers grown worldwide. However, studies on genetics and breeding of this species are rare, when compared to other Capsicum species, manly in relation to physiological seed quality traits. In this sense, this study aimed to evaluate the combining ability of “dedo-de-moça” chili pepper in relation to physiological seed quality traits, determine the gene effects involved in the expression of these traits, and identify promising hybrid combinations. Crosses among five parents (Hortivale, Horticeres, Brs Mari, UEL 110 and UEL 111) in a full diallel mating design, resulted in 20 F1 hybrids. Griffing’s diallel model was used to estimate general and specific combining ability (GCA and SCA, respectively) as well as the reciprocal effect (RE). Wide genetic variability was observed for all evaluated traits. Significant effects of GCA, SCA and RE were also verified for all traits, showing that additive, non-additive and cytoplasmic effects are involved in the genetic control of physiological seed quality. Non-additive effects were predominant for all traits, being UEL 111 (♂) × Hortivale (♀) and Hortivale (♂) × UEL 110 (♀) considered promising hybrids for obtaining more vigorous seeds with higher germination and greater longevity.

title: Multicategorical descriptors for creole genotypes of Amazon chicory (Eryngium foetidum)

description: ABSTRACT The knowledge concerning genetic variability of creole genotypes by using morphological descriptors in species such as Amazon chicory is crucial to quantify local diversity and protect improved cultivars. Accordingly, this study aimed to propose multicategory leaf morphological descriptors for Amazon chicory species. To achieve that, an experiment was arranged in randomized block design with four repetitions. The treatments comprised eight creole genotypes of Amazon chicory, which were obtained from local producers’ collection. The proposed multi-categorical descriptors are based on limb shape, leaf apex shape, leaf base shape, leaf margin, bract consistency, and bract margin traits. Once the multicategorical clustered data were obtained, they were transformed into a dissimilarity matrix. The limb shape presents dissimilarity, being either lanceolate or spatulate; as well as for leaf margin, which can be dentate or serrate. Thus, both limb shape and leaf margin constitute important qualitative descriptors for genetic diversity assessment and conservation for Amazon chicory, besides a recommended tool to be exploited in breeding programs.

title: Selection of kale accesses to dehydration post-harvest by model identity test

description: ABSTRACT The selection of kale genotypes more resistant to dehydration is important, since this product is marketed fresh and characterized as perishable. For the post-harvest study, the adjustment of regression models is useful. However, when there are many treatments, it is difficult to identify the superior one through the graphical representation of the curves. In this sense, the model identity test groups the curves establishing genotypes that have statistically similar behavior. Thus, we aimed to select kale accesses for post-harvest dehydration using the model identity test. The accumulated loss of fresh matter of 22 kale genotypaes was evaluated, being 19 of the germplasm bank of the UFVJM and three commercial cultivars (COM). The model identity test was used for the statistical grouping of the regression curves. The UFVJM-19 and UFVJM-32 accessions had lower rates of dehydration as a function of time. The test facilitated the interpretation of the results, with a reduction of 22 to six regression curves, helping to select the best genotypes. The UFVJM-19 and UFVJM-32 accessions are the most indicated because they present lower post-harvest dehydration, being the most recommended for commercialization.

title: Virus-free garlic: yield and commercial classification as a function of plant spacing and seed size

description: ABSTRACT Studies on the interaction between garlic plant density and virus-free seed size are scarce in Brazil. Thus, this study was installed to evaluate the effect of plant spacing and seed size on garlic traits and yield for infected and virus-free bulbs. Treatments were arranged in a randomized block design and 2x5x3 factorial combination [infected and virus-free bulbs, five plant spacings (210, 260, 300, 360, and 390 cm2 per plant), and three bulbous seed sizes (sieve one, two, and three)]. The highest bulb yield was observed for virus-free seeds at a plant spacing of 390 cm2 plant-1, while the highest commercial yield was verified for 210 cm2 plant-1 spacing. The combination of virus-free seeds, larger bulbs, and 332 cm2 plant-1 spacing promoted the highest leaf area index. For virus-free garlic, lower plant densities resulted in higher yields and garlic bulb quality. The best option for higher yields and improved commercial quality bulbs was the use of medium-sized virus-free bulbils at a plant density of about 300 thousand plants ha-1.

title: Nitrogen levels via fertigation and irrigation depths in the arugula culture

description: ABSTRACT In vegetables, especially the leafy ones, nitrogen (N) and water are essential in its growth, being N the second most absorbed and identified nutrient in the arugula leaf tissue. Water is essential for horticultural crops, so its use must be rational in order to achieve high yield. The objective of this study was to evaluate the effect of nitrogen levels and irrigation depths on the productive characteristics, the total leaf chlorophyll index (ICF) and nitrogen contents in the arugula culture. The experiment was arranged in a randomized block design subdivided in plots, with two factors: A) nitrogen levels applied in coverage (25, 50, 100, 125 and 150 mg dm-3) and B) irrigation depths [(50 and 100% of the available water capacity (AWC)]. At harvest, 37 days after transplantation (DAT), we observed a significant effect of the treatments when individually analyzed, and also a significant interaction between factors of the analyzed variables. The nitrogen content in the plant showed no effect for irrigation depths. However, the highest content was found in the level of 129 mg dm-3 (27.8 g kg-1), corresponding to an increase of 26% in relation to the lowest level (25 mg dm-3; 22.07 g kg-1). In conclusion, the supply of 150 mg dm-3 nitrogen and full irrigation management (100% of AWC) provided substantial increase in height, leaf area and fresh mass of aerial part of the plant.

title: Growth and production of basil under different luminosity and water replacement levels

description: ABSTRACT Basil is used as spice and for medicinal purposes. Its growth is influenced by environmental factors, mainly soil moisture and air temperature. Thus, this study was installed to evaluate growth and production of basil under different levels of luminosity and water replacement. The experimental design was completely randomized, with six replicates, arranged in split plot scheme, with three luminosity levels in the plots (full sun, 50% and 70% shading) and four water replacement levels in the subplots (25, 50, 75 and 100% ETc). We evaluated plant height, stalk diameter, number of leaves and branches, root system volume, the largest root length, fresh and dry mass of roots and leaves. Data were submitted to variance analysis to observe significant differences between treatments and interactions. Luminosity effects were evaluated using Tukey test (p≤0.05%) and the effects of water regime, with the aid of regression analysis. According to data, 50% shading and 100% water replacement, lost through crop evapotranspiration, resulted in higher values of plant height, stalk diameter, branch growth, fresh and dry mass of leaves, and number of leaves. Full sun environment and 100% water replacement provided an increase in root dry mass and volume.

title: Spear leaf in determining the harvest timing of peach palm heart

description: ABSTRACT The harvest timing of peach palm stems for heart-of-palm production is mainly defined by the height and diameter of the stem. Spear leaf parameters could be used in the field to obtain a higher heart-of-palm yield. The aim of this study is to verify if the length and opening of the spear leaf are related to the peach palm heart production. Three harvests were carried out in Campinas (SP), over a period of one year. Before harvest the plants were measured: main stem circumference, height, number of tillers and leaves, length and degree of spear leaf opening. After stem harvest, heart-of-palm production was evaluated. Regardless of the harvest date, the length of the first-rate heart-of-palm was longer when the spear leaf was open. Total mass production of heart-of-palm as a function of spear leaf opening is variable and dependent on weather conditions. When there was a difference in total mass production, this was higher when spear leaf was open. There was no correlation between spear leaf length and total heart-of-palm production. Although there may be an increase in the number of stalks, this had not resulted in a significant effect in terms of mass. The insertion of the spear leaf openness criterion in the determination of the harvest timing may not be worthwhile, since the payment to the producer occurs on the total mass of first-rate heart-of-palm, which may not be higher due to the degree of spear leaf opening.

title: Evaluation of onion genotypes to slippery skin caused by Burkholderia gladioli pv. Alliicola

description: ABSTRACT Onion’s (Allium cepa) slippery skin caused by Burkholderia gladioli pv. alliicola is one of the bacterial diseases that stand out in producing regions of the Brazilian Northeast. Given the importance and potential threat of this disease, and the absence of resistant varieties, the aim of this study was to evaluate the reaction of onion genotypes to slippery skin and to analyze the tolerance stability of the most promising genotypes to different strains of the bacteria. Nine strains of B. gladioli pv. alliicola were artificially inoculated in onion bulbs cv. Baia Periforme and the three most aggressive strains (CCRMBG39, CCRMBG172 and CCRMBG212) were selected to evaluate the tolerance to the disease. Fifty-eight onion genotypes were challenged with the most aggressive strain (CCRMBG39) and 34 genotypes were considered as tolerant, with a disease severity varying from 9.79 to 13.42 mm. The fifteen most promising genotypes and the most susceptible genotype were selected to study the stability of tolerance using the three selected strains. The genotypes F2 (EHCEB 20151030 x EHCEB 20133015), Cascuda T5, Crioula Mercosul, Juporanga, EHCEB 20111036, Cascuda T6 and EHCEB 20142028 remained tolerant to the disease when inoculated with the three strains, with a disease severity ranging from 9.13 to 14.19 mm. In view of these results, we conclude that these genotypes can be used as potential sources of tolerance to onion slippery skin.
