Peppers of the Capsicum annuum species are the most suitable for use in ornamentation, for having characters that confer aesthetic value, for being easy to cultivate and for good adaptability in pot. Despite the great variability that exists, in Brazil few commercial varieties are used for this purpose. It is of interest to the plant breeder, an ideotype that contains all the characteristics of interest for commercialization. The aim of the present study is to evaluate and select C. annuum genotypes, with potential for ornamentation that most closely resemble the proposed ideotype. 14 quantitative traits and seven qualitative traits were evaluated in 29 C. annuum genotypes, in a completely randomized design with five replications. The cultivar Calypso was used as an ideotype for presenting desirable characters to the ornamental pepper market. Nine genotypes were selected as the most similar to the Calypso ideotype (ideotype), with the potential to be used in future crossings between them and / or with the ideotype.

Aim: This study was conducted to develop liquid enhancer containing KCl, TU, GA, and SA for germination of drought-stressed Oryza sativa subsp. indica cv. MR284 seed. Study Design: All experiments were conducted in a completely randomized design. Two steps were involved in the development process which are to select an ideal concentration for each KCl, TU, GA, and SA, and to find an ideal combination of chemicals from the selection of ideal concentrations acquired in step 1 to form liquid enhancer. There were 20 treatments for step 1 and 9 treatments for step 2. All of these treatments with 6 replicates. Place and Duration of Study: Department of Biology, Faculty of Science, University Putra Malaysia, between June 2018 and December 2018. Methodology: The sterilized rice seed cv. MR284 was stressed in the -1.2 Mpa PEG 6000 solution for three days and germinated in the KCl, TU, GA, and SA solution in a series of concentration for 10 days, in a controlled room. Seed germination was observed daily. Results: In the first step, drought-stressed rice seed showed the best germination performance in the 30 mM of KCl, 2.0 mM of TU, 0.24 mM GA, and 0.5 mM SA. Meanwhile, in the second step, the drought-stressed rice seed showed the best germination performance in the combination of 30 mM KCl + 2.0 mM TU + 0.24 mM GA + 0.5 mM SA. The best germination performance was evaluated by the highest germination percentage (%), germination index, seed vigor, leaf length, root length and biomass. Conclusion: Therefore, the combination treatments of 30 mM KCl + 2.0 mM TU + 0.5 mM SA was found to be the most effective and simplest liquid enhancer formula that has an ability to enhance seed germination of drought-stressed rice cv. MR284 seed.

Abstract: The objective of this work was to estimate the damage caused by Meloidogyne enterolobii in okra (Abelmoschus esculentus) and to verify the reliability of the reproduction factor as a suitable measure for selecting resistant okra genotypes. Increasing populations of M. enterolobii - 0, 500, 1,500, 3,000, 5,000, and 7,000 eggs and second-stage juveniles (J2) per plant, - were evaluated, in a completely randomized design. The pathogen showed a parasitism pattern similar to that of M. incognita, causing a significant decrease in morphological and agronomic traits. The pathogen reproduction factor should be used in the selection of okra genotypes for tolerance to M. enterolobii, in populations above 3,000 eggs or J2.

Parsley seeds are commercialized without classification by size during processing, unlike other crops. This classification procedure allows the standardization of seed size for high precision in sowing, disposal of unwanted material, and selection of high quality seeds. The aim of this study was to verify the effect of seed size on germination, vigor, and yield performance of two parsley cultivars. Seeds from eight lots of parsley of ‘Portuguesa’ and ‘Chacareira’ cultivar were separated into three size classes, represented by the seeds retained in the sieves of 0.84, 1.00 and 1.41mm mesh opening. After classification, seeds were evaluated in the laboratory for water content, germination percentage, first count, and thousand seed weight. In the field, the fresh and dry weight of aerial part and the final number of plants (stand) were evaluated after 78 days of sowing. The experimental design was the completely randomized design in an 8 x 3 factorial scheme (eight lots and three sieve opening) with four replicates, for both cultivars. Data obtained were subjected to analysis of variance and means were compared using Tukey test at 5% probability level. It was concluded that the parsley seeds separated by the 1.41 mm sieves showed higher vigor, and consequently, greater success in stand establishment at the field than those separated by other sieve size. The use of sieves in the classification of parsley seeds helps in obtaining lots with superior physiological quality.

Sausage is a popular food for both children and adults. The main problem in sausage processing is their short shelf life. Synthetic preservatives such as nitrites are often added to sausage dough to extend the shelf life of sausages. Preservatives such as nitrites, if consumed too often can have harmful effects on health. The content of active compounds found in jasmine flowers is expected to be used as a source of natural preservatives in the processing of tempeh sausage in this study. This study aims to determine the acceptability of sausage formulations with the addition of natural preservatives. This study consisted of 3 treatments, namely tempeh sausage with extract variations of 0%, 0.1%, and 0.25%. This study used a completely randomized design (CRD). The concentration of jasmine flower extract had a significantly different effect on the taste of tempeh (p <0.05), where the higher the concentration of jasmine flower extract added to the tempeh sausage, the panelists' preference for the taste of the tempeh sausage would decrease. This is because the two basic ingredients of sausage, namely tempeh and jasmine flowers, already have a specific basic taste. The selection of preservatives made from natural ingredients can be a choice in developing food products, to minimize the use of synthetic preservatives in food products that are carcinogenic.

ABSTRACT Ornamental plants are all plants grown for their beauty and are commonly used in gardening and landscaping. The colorful fruits and varied foliage colors that typify ornamental peppers provide a vibrant garden display that rivals other ornamental plants. This study aimed to evaluate the potential ornamental use of eight pepper accessions, Capsicum annuum, from the Capsicum Germplasm Bank of the Universidade Federal do Piauí, using qualitative and quantitative descriptors. The experiment was carried out in a greenhouse at the Department of Plant Science, Centre of Agricultural Sciences of Universidade Federal do Piauí, where the accessions were evaluated through a completely randomized design, with eight replicates, one plant per plot, and characterized based on 35 descriptors, 23 of which were qualitative and 12 quantitative. Data on quantitative descriptors were submitted to univariate analysis of variance, followed by Scott-Knott clustering test at 5% probability. Data on qualitative multicategorical descriptors were considered based on observations of statistical mode. The eight accessions evaluated have ornamental potential and are within the standards established by the Instituto Brasileiro de Floricultura. The accessions BAGC 98, 100, 203, 207, 224, and 236 accessions are suitable for cultivation in pots, while BAGC 220 is suitable for garden cultivation. BAGC 199 is the most promising accession because it supports all quality criteria required for size, foliage, flowers, and fruit proposed by the Veiling Holambra Cooperative.

Dryland area in Indonesia reaches 108.8 millions ha (69.4%) of the total dry land with the potential to expand the area of food crops reaching 7.1 million ha, which is dominated by ultisol and oxisol soil types. Plant constraint cultivation on ultisol soil types is the acidic soil pH with high Al and Fe levels. One of the efforts that can be made to cultivate plants on ultisol soil is the selection of plants that are tolerant of Fe stress. This study aimed to determine a tolerance level and F6 red rice lines that were tolerant of iron (Fe) stress in ultisol soils. The experimental design used was factorial Completely Randomized Design (CRD) consisting of 2 factors, the first factor consisted of 12 treatments (10 test lines and 2 comparison varieties) and the second factor  was iron stress with concentrations (0 ppm and 551,55 ppm). The stress was applied after 3 WAP. The stress resistance test to iron (Fe) should that all lines of red rice F6 on ultisol soils have a score of 1 which indicates the stress tolerance of Fe at a concentration of 551,55 ppm Fe. The 23A-56-30-25-12 and 23A-56-30-25-13 lines were the best lines that were tolerant of 551,55 ppm iron (Fe) stress with the highest growth and yield. The lines tested can be developed on ultisol soils because they are tolerant of Fe.

ABSTRACT Cyperus iria (CYPIR) is one of the main weeds in irrigated rice crops. The intense chemical control with acetolactate synthase (ALS) inhibiting herbicides favors the selection of cross-resistance. This study aimed to evaluate the crossresistance of CYPIR to ALS-inhibiting herbicides in irrigated rice in Rio Grande do Sul. Two experiments arranged in a factorial scheme, in a completely randomized design, with four replications were conducted. Experiment I consisted of resistant (CYPIR-R) and susceptible (CYPIR-S) biotypes and ALS-inhibiting herbicide doses: imazethapyr (106 g a.i. ha-1); pyrazosulfuron-ethyl (20 g a.i. ha-1); penoxsulam (36 g a.i. ha-1) and, as an alternative herbicide, bentazone (960 g a.i. ha-1); corresponding to 0; 1/16; 1/8; 1/4; 1/2; 1; 2; 4; 8 and 16x (x = maximum registered dose). Experiment II followed the same procedures, with doses of 0; 1/64; 1/32; 1/16; 1/8; 1/4; 1/2; 1 and 2x for CYPIR-S and 0; 1/2; 1; 2; 4; 8; 16; 32; 64 and 128x for CYPIR-R; including bispyribac-sodium (50 g a.i. ha-1). The variables evaluated were: visual control at 7, 14, 21 and 28 days after the treatments (DAT) and shoot dry matter (SDM) at 28 DAT. The results, fitted by nonlinear regression, show varied and high levels of cross-resistance of CYPIR-R to ALS-inhibiting herbicides from the group of imidazolinones, sulfonylureas, triazolopyrimidines and pyrimidinyl(thio)benzoates. Bentazone can be used as an alternative herbicide, however, not exclusively in the control of this biotype.
