title: Phytopathogen resistance of phytohormone-deficient and low-sensitivity mutant tomatoes

description: ABSTRACT This study broadens the knowledge of plant-pathogen interactions using phytohormone-deficient and low-sensitivity mutant tomatoes. The experiment was performed under greenhouse conditions and the mutants used were provided by the HCPD laboratory, at ESALQ/USP. The hormone mutant Never ripe showed a larger final lesion size when inoculated with Botrytis cinerea, whereas curl3 was relatively resistant to this pathogen and more susceptible when inoculated with Phytophthora infestans. The transgenic 35S :: nahG was more susceptible to Oidium lycopersici, and the double mutant dgt, Nr more resistant. The low sensitivity to brassinosteroids confers greater susceptibility to P. infestans and higher resistance to B. cinerea. The deficiency of the hormone auxin promotes high resistance to diseases caused by O. lycopersici, P. infestans and B. cinerea.

title: Adaptability and stability of maize genotypes in growing regions of central Brazil

description: ABSTRACT This study aimed to estimate and compare parameters of adaptability and stability for maize grain yield in a variety of environments by different projection methods. Data from experiments on 36 maize genotypes, in simple lattice 6x6, in 2012/13 season performed at nine growing locations in central Brazil were used. Adaptability and stability analyses were performed using the methods of Lin & Binns (1988) with decomposition, MHPRVG through REML/BLUP, AMMI-Biplot, and GGE-Biplot analysis. These methods have similarities in terms of genotype ordering but differ in precision and amount of information provided on genotype-environment (GxE) interactions. When compared to GGE-Biplot, AMMI method retained a good percentage of the total square sum, based on pattern of GxE interaction. The method of Lin & Binns with decomposition is similar to MHPRVG, but these one is more accurate, practice and informative. MHPRVG and GGE-Biplot methods should be used together to select the most promising genotypes. The genotypes G5 and G8 can be recommended for cultivation in central Brazil due to their adaptability, stability, and yield.

title: Adventitious rooting of cultivars and clonal selections of Prunus spp. rootstock under intermittent mist system

description: ABSTRACT To reduce peach tree losses due the Peach Tree Short Life (PTSL), the main research line in Brazil is to select tolerant rootstock and perpetuate it by cloning methods. The objective was to evaluate adventitious rooting capacity of softwood cuttings of three cultivars and several clonal rootstock selections of Prunus spp., under intermittent mist system. Two trials were conducted and ‘Capdeboscq’, ‘Okinawa’ (P. persica) and ‘Sharpe’ [‘Chickasaw’ (P. angustifolia Marsh.) x Prunus spp.] were used as reference cultivars. After 53 days (trial 1) and 72 days (trial 2) from the cutting setting, we conclude that softwood cuttings under intermittent mist system are a feasible way to propagate peach rootstock selections of 2010/2011 PTSL selection cycle. Root quality was satisfactory in most selections, with high percentages of cuttings suitable for transplanting and excellent root number and root length. OS-GRA-10-17, VEH-GRA-10-31, VEH-GRA-10-32, VEH-GRA-10-37 and VEH-GRA-10-38 selections had the highest mortality and the lower percentages of live rooted cuttings. The ease of vegetative propagation must be taken into account in more promising rootstock.

title: Selectivity and residual weed control of pre-emergent herbicides in soybean crop

description: ABSTRACT The use of pre-emergent herbicides is important for the current agricultural production systems that present weeds resistant to herbicides. Considering the complexity of using these products, the objective of this work was to evaluate their selectivity and residual weed control in soybean crops and their effect on the weeds Amaranthus hybridus, Bidens pilosa, Digitaria insularis, Eleusine indica, and Euphorbia heterophylla. The herbicide selectivity experiments were conducted under field conditions in the 2017/18 and 2019/20 crop seasons and the herbicide efficacy experiments were conducted under greenhouse conditions. The herbicides s-metolachlor and flumioxazin can be applied on day of the soybean sowing without causing significant grain yield losses. Diclosulam and sulfentrazone are safe for soybean crops when applied at least 14 days before sowing. The herbicides used proved to be good options for weed management systems for soybean crops; flumioxazin and sulfentrazone were the herbicides that promoted the best control for all evaluated weed species and ensured a residual effect of at least 30 days.

title: Morphological characterization of fruits, endocarp, seed and seedlings of cajá-manga (Spondias dulcis)

description: ABSTRACT The Cerrado biome has several species that can generate income, and the cajá-manga is one of these native species with great potential but with scarce information about its morphological characterization. Thus, this work aimed to characterize the fruit, endocarp, seeds, and seedlings of cajá-manga morphologically. The fruits were evaluated by the characteristics of the length, width, and diameter of the fruit, endocarp, and seeds, the number of loculi, and the weight of fruits and endocarp. The plantlets were evaluated for the number of seedlings per endocarp, number of leaflets, number of leaflets of the 3rd and 4th leaves, stem diameter, length of the shoot and root, root and shoot dry matter and data analyzed by descriptive analysis. The morphometric characteristics of the fruits, endocarp, and seeds were analyzed using the Scott-Knott test. The morphological characteristics of the fruits, the endocarps, the seeds, and the plantlets of cajá-manga varied within the mother plants. These results can be used as a basis for future selection of plants with desirable characteristics on breeding programs.

title: Agronomic performance of onion cultivars as affected by phosphate fertilization

description: ABSTRACT Phosphorus (P) is an important nutrient for obtaining high yields and has been the one that most often limits production. The objective of this study was to evaluate the agronomic performance of onion cultivars as a function of phosphate fertilization. The experiments were installed at the Rafael Fernandes Experimental Farm, of the Federal Rural University of the Semi-Arid Region, Mossoró-RN, Brazil, from July to October 2016 and from June to October 2017. The design used was randomized blocks, in a 2 x 6 factorial scheme, with four replicates. The treatments consisted of the combination of two onion cultivars (IPA11 and Rio das Antas) and six P doses (0, 60, 120, 180, 240 and 300 kg ha-1 P2O5). The economical doses of P, associated with the maximum marketable yields of onion were estimated at 212.45 and 207.65 kg ha-1 of P2O5, respectively for the cultivars IPA 11 and Rio das Antas. In general, the cultivar Rio das Antas was more productive than IPA 11, in the two growing periods.

title: Jambu varieties performance under shading screens

description: ABSTRACT Shading screens have been extensively used in leafy-vegetables production system. Nevertheless, there is still a substantial lack of knowledge regarding the effects of this technology on the performance of non-conventional vegetables such as jambu, a typical staple food with social and economic importance for the Amazon region. This study thus aimed to evaluate the effects of shading screens on the agronomic performance of two jambu varieties. The experiment was performed in a randomized block design, in a 4 x 2 factorial scheme (shading screens and varieties), with four replications. Plants were then evaluated for morphophysiological and yield parameters. As an outcome, there was no significant interaction between shading screens and varieties for assessed variables. On the other hand, the shading screen itself affected significantly jambu varieties yield. The 50%-shading screen for instance provided both higher fresh weight accumulation and higher shoot water content. Moreover, 50%-shading screen led to an increase in both productivity (Kg m-2) and yield (bunch m-2) by 46%, respectively. The use of 50%-shading screen improves the agronomic performance of jambu, hence being a suitable technological alternative available for the farmers.

title: Increased yield and nutrient content of Tropaeolum majus L. with use of chicken manure 1

description: ABSTRACT Nasturtium (Tropaeolum majus L.) is an unconventional plant or vegetable grown for ornamental, food and medicinal purposes. However, information on cultivation of the species involving organic residue is incipient. Therefore, aimed to evaluate plant growth, flower yield, and nutrient contents of leaves and flowers of Nasturtium cultivated with addition of chicken manure. Five doses of chicken manure were studied, applied in the soil incorporated (I) (1, 6, 10, 14 and 19 t ha-1) and cover (C) (1, 6, 10, 14 and 19 t ha-1) forms, using the experimental array Plan Puebla III, leading to nine combinations of doses and forms of adding the chicken manure, in randomized blocks with four replicates. The greatest plant height (35.75 cm) was achieved at 168 days after transplanting (DAT) under 10 t ha-1 I and 10 t ha-1 C. The greatest yield terms of in number (15.4 million ha-1) and fresh (10.45 t ha-1) and dry weights (0.849 t ha-1) of flowers were found by using doses close to 10 t ha-1 I and 10 t ha-1 C. To obtain the best development and yield of Nasturtium flowers, 10 t ha-1 I and 10 t ha-1 C of chicken manure should be used.

title: Use of methyl jasmonate in bird of paradise

description: ABSTRACT The MeJA has been shown to be promising in reducing the damages caused by cold and maintaining the quality in several products. Nevertheless, few studies are conducted with flowers and there are no studies of its use in bird of paradise. The objective of this study was to determine whether the pulsing application with MeJA submitted to cold storage promotes physiological changes of the bird of paradise. Flowers were placed in solutions of 200 g L-1 sucrose added with 100, 250 and 400 μmol L-1 MeJA and control without MeJA, for 24 h. The stems were transferred to containers with water at 5 ºC for 28 days. During storage, the water absorption, transpiration and fresh mass were reduced, while the extravasation of electrolytes and phenolic compounds increased. The application of MeJA did not reduce the loss of fresh mass and extravasation of electrolytes. The application of 400 μmol L-1 MeJA has increased peroxidase activity since day 14 of storage. It is concluded that the application of MeJA with pulsing under refrigeration does not promote positive physiological changes for the maintenance of the quality in bird of paradise flowers.

title: Shoot growth, tuber yield and quality of two potato cultivars as affected by prohexadione-calcium application

description: ABSTRACT This study evaluated the effects of the rates and timings of prohexadione-calcium (prohexadione-Ca) application on shoot growth, tuber yield, and quality of two potato cultivars (Agata and Mondial). An experiment with each cultivar was carried out in a greenhouse using a randomized block design with four replications. Treatments consisted of a control and single or sequential foliar applications of prohexadione-Ca at the rate of 50 or 100 g ha-1 (50 g ha-1 applied once, 50 g ha-1 applied twice, 50 g ha-1 applied three times, 100 g ha-1 applied once, 100 g ha-1 applied twice, and 100 g ha-1 applied three times). Prohexadione-Ca application changed the distribution pattern of tuber size in both cultivars. A rate of 100 g ha-1 prohexadione-Ca was applied three times between the stages of tuber initiation and tuber bulking, making the haulm length of the plants short for a long time. Prohexadione-Ca application did not alter the tuber yield and quality of the cultivar Agata, but 50 g ha-1 applied three times or 100 g ha-1 applied twice increased tuber yield in the cultivar Mondial. Only in the cultivar Mondial, 50 g ha-1 prohexadione-Ca applied three times increase tuber dry matter, starch, and protein contents.
