Objetivou-se avaliar os aspectos agronômicos da formação da inflorescência de duas cultivares de couve-flor, em ambiente protegido, sob diferentes níveis de irrigação com base na aferição de sua evapotranspiração. O arranjo experimental foi em blocos casualizados, com quatro repetições, em esquema fatorial de 2 x 3, sendo dois híbridos e três regimes hídricos. Houve resposta significativa do fator híbrido Barcelona e as diferentes lâminas de irrigação para a variável massa fresca da inflorescência. O híbrido Viena apresentou melhor desempenho produtivo, não variando sua massa fresca de inflorescência mesmo com as alterações de disponibilidade hídrica. A massa fresca das folhas possui forte correlação com a massa fresca da inflorescência, principalmente, para o híbrido Barcelona. O número de folhas acima de 15 contribui positivamente para o crescimento do diâmetro da inflorescência em couve-flor.   Palavras-chave: Brassica oleracea var.botritys, lâminas de irrigação, fonte-dreno.     ANDREAN, A.

AGRONOMIC ASPECTS OF THE FORMATION OF THE INFLORESCENCE OF CAULIFLOWER UNDER DIFFERENT WATER CONDITIONS     2 ABSTRACT   Understanding the behavior of cauliflower under different water availability conditions can be an important tool to assist farmers, that will be able to make the best decisions regarding the planting time and the choice of the cultivar, in addition, even if the plant materials have the same classification of planting time and seasonality, performance and physiological means of production are often not the same. The objective was to evaluate the agronomic aspects of the formation of the inflorescence of two cauliflower cultivars, in a greenhouse under different levels of irrigation based on the measurement of their evapotranspiration. The experimental arrangement was in randomized blocks with four replications in a 2 x 3 factorial scheme, two hybrids and three water regimes. There was a significant response from the hybrid factors Barcelona and the different irrigation depths for the variable fresh mass of the inflorescence. The Viena hybrid showed better productive performance, with its fresh inflorescence mass not varying even with changes in water availability. The fresh weight of the leaves has a strong correlation with the fresh weight of the inflorescence, mainly for the Barcelona hybrid. The number of leaves above 15 contributes positively to the growth of the diameter of the cauliflower inflorescence.   Keywords: brássica olerácea var. botritys, irrigationplates, souce-sink.

A system to propagate tronchuda (Brassica oleracea var. tronchuda Bailey syn. costata L.) from main stem and side shoot cuttings was developed by removing the main stem (three to four leaves) and, later, side shoots from S-week-old plants, transplanting them into small pots, and growing them under a mist system for 4 weeks. New root growth appeared on cuttings within 3 weeks. Rooting frequency varied among cultivars and explant types. For all cultivars, side shoot cuttings rooted better than main stem cuttings (99.7% vs. 84.8%). For all cultivars, seed-propagated plants and side shoot cuttings produced leaves with significantly higher fresh weight than the main stem cuttings for three of the five cultivars. The average number of leaves per plant for four cultivars was, however, not significantly affected by propagation method. Average leaf count and fresh weight per plant were significantly higher for `Portuguesa' than for `Ana Maria'. `Couve Penca'. `Vilinda', and `Penca de Chaves' for all three propagation sources.

Soybean plant [Glycine max (L.) Merr.] Is a food crop that is a source of fat, protein, and minerals. Drought stress is a major obstacle in the cultivation of soybean plants, which causes the synthesis of excessive amounts of Reactive Oxygen Species (ROS) which triggers oxidative stress. Hydrogen peroxide (H2O2) is the most stable ROS, in low concentrations it can act as a signaling molecule and activate an antioxidant defense system to protect plants from oxidative stress. The study was conducted at the Plant Structure and Function Biology Laboratory of Diponegoro University. The study aims to determine the effect of H2O2 treatment on the condition of different levels of water availability on the vegetative growth of soybean plants variety Deja 1. Research using a completely randomized design (CRD) 4x2 factorial pattern. The first factor is H2O2 concentration (0 0.5 1 and 2 mM). The second factor is the level of water availability (100 and 35% of field capacity). Each treatment was repeated 5 times. Quantitative data were analyzed by Analysis of Variance (ANOVA) followed by DMRT test at 95% confidence level. The results showed that there was an interaction between the H2O2 concentration factor and the level of water supply to the canopy fresh weight. The 2 mM H2O2 treatment at 100% water availability and 1 mM H2O2 with 35% water availability increased vegetative growth as indicated by the canopy and root fresh weight parameters, number of leaves, stomata opening width, relative water content. Based on the results of the study it can be stated that the exogenous H2O2 treatment of leaves with certain concentrations at all different levels of water availability can increase the vegetatif growth of soybean variety of Deja 1.

Abstract:In 1987, the American Rheumatism Association issued a set of criteria for the classification of rheumatoid arthritis (RA) to provide a uniform definition of RA patients. Fuzzy set theory and fuzzy logic were used to transform this set of criteria into a diagnostic tool that offers diagnoses at different levels of confidence: a definite level, which was consistent with the original criteria definition, as well as several possible and superdefinite levels. Two fuzzy models and a reference model which provided results at a definite level only were applied to 292 clinical cases from a hospital for rheumatic diseases. At the definite level, all models yielded a sensitivity rate of 72.6% and a specificity rate of 87.0%. Sensitivity and specificity rates at the possible levels ranged from 73.3% to 85.6% and from 83.6% to 87.0%. At the superdefinite levels, sensitivity rates ranged from 39.0% to 63.7% and specificity rates from 90.4% to 95.2%. Fuzzy techniques were helpful to add flexibility to preexisting diagnostic criteria in order to obtain diagnoses at the desired level of confidence.

Relative sensitivity of selected vegetable and weed seedlings to ultraviolet-B (UV-B) radiation (280–320 nm) was investigated. Seedlings were grown for 4 weeks in a greenhouse, in chambers equipped with UV-B-emitting fluorescent tubes and Mylar (control) and cellulose acetate (UV-B) filters. UV-B radiation reduced seedling height, leaf area, and leaf fresh weight in tomato (Lycopersicon esculentum `Cour Di Bue'), broccoli (Brassica oleracea var. Italica `Purple Sprouting'), cabbage (Brassica oleracea var. Capitata `Red Drumhead'), and cucumber (Cucumis sativus `Straight Eight'), leaf area and leaf fresh weight in beet (Beta vulgaris `Cylindra' and `Early Wonder'), seedling height and leaf area in spinach (Spinacia oleracea `Long Standing Bloomsdale'), lettuce (Lactuca sativa ``Red Salad Bowl Everest') and `Savoy' cabbage, and seedling height in `Chinese Tip Top' cabbage and lettuce (`Saladin'). `Winterton' cabbage was not affected. UV-B radiation decreased leaf area and leaf fresh weight in common chickweed (Stellaria media) and corn spurry (Spergula arvensis) and seedling height in green foxtail (Setaria viridis) and redroot pigweed (Amaranthus retroflexus). Tillering was stimulated in response to UV-B in green foxtail. There was no effect of UV-B on lady's-thumb (Polygonum persicaria) growth. Leaf number was not affected by exposure to UV-B in any species. The differential morphological sensitivity of vegetable and weed seedlings may result in altered competitive relationships under enhanced UV-B levels expected with the depletion of the earth's ozone layer.

Soil water availability is the main cause of reduced productivity, and the early development period most sensitive to water deficit. This study aimed to evaluate the drought resistance of the varieties of sugar-cane RB867515 and SP81-3250 during the early development using different levels of water deficit on four soil depths. The experiment was conducted at the Department of Biosystems at Escola Superior de Agricultura "Luiz de Queiroz" (ESALQ/USP) in a greenhouse in soil classified as Oxisol, sandy loam texture (Series "Sertãozinho"). Once exhausted the level of available water in the soil, the dry strength of the studied strains are relatively low. Water balance with values less than -13 mm cause a significant decrease in the final population of plants, regardless of the variety, and values below -35 mm, leads to the death of all plants.

An experiment was conducted with a local cultivar of garlic to study the effects of planting date and gibberellic acid on the growth and yield of garlic at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during November 2001 to April 2002. Early planting influenced the plant height, leaf number, bulb diameter and total dry matter. With the delay in planting time starting from November 7, the yield was chronologically reduced in later plantings. Significantly the highest bulb yield (2.67 t/ha) was recorded when planting was done on November 7 and lowest yield (0.92 t/ha) was obtained from December 22 planted crop. Bulb yield was higher in control plants than those of GA3 treated plants. The interaction effects of planting date and different concentrations of GA3 differed significantly in respect of plant height, number of leaves, bulb diameter and dry weight of roots, leaves and bulbs and yield of garlic.

Different Levels

ABSTRACTA classification is proposed, based mainly on major element analytical data plotted in a coherent set of three simple chemical-mineralogical diagrams. The procedure follows two complementary steps at two different levels. The first is concerned with the individual sample: the sample is given a name (e.g. granite, adamellite, granodiorite) and its chemical and mineralogical characteristics are determined. The second one is more important: it aims at defining the type of magmatic association (or series) to which the studied sample or group of samples belongs. Three main types of association are distinguished: cafemic (from source-material mainly or completely mantle-derived), aluminous (mainly or completely derived by anatexis of continental crust), and alumino-cafemic (intermediate between the other two types). Subtypes are then distinguished among the cafemic and alumino-cafemic associations: calc-alkaline (or granodioritic), subalkaline (or monzonitic), alkaline (and peralkaline), tholeiitic (or gabbroic-trondhjemitic), etc. In the same way, numerous subtypes and variants are also distinguished among the aluminous associations using a set of complementary criteria such as quartz content, colour index, alkali ratio, quartz–alkalies relationships and alumina index.Although involving a new approach using partly new criteria, this classification is consistent with most of the divisions used in previous typologies. The method may also be used in the classification of the volcanic equivalents of common plutonic rocks.
