1. Atributos físico-químicos de Brassicas cultivadas sobre diferentes coberturas em plantio direto
RESUMO A couve-flor e o repolho são plantas que necessitam de elevados aportes de nutrientes em curtos períodos de tempo; contudo, o uso intensivo de fertilizantes inorgânicos pode causar o desequilíbrio nutricional destas plantas e influenciar a qualidade do produto final. Neste estudo avaliou-se a composição química e a produtividade da couve-flor e

2. Forced-air, vacuum, and hydro precooling of cauliflower (Brassica oleracea L. var. botrytis cv. Freemont): Part II. Determination of quality parameters during storage
Cauliflower heads, which were precooled using four different methods including vacuum, forced-air, and high and low flow hydro precooling, were stored under controlled atmosphere and room conditions. Controlled atmosphere conditions (CA) were as follows: 1°C temperature, 90 ± 5% relative humidity, and 0:21 [(%CO2:%O2) – (0:21) control] atmosphere composi

3. Forced-air, vacuum, and hydro precooling of cauliflower (Brassica oleracea L. var. botrytis cv. Freemont): part I. determination of precooling parameters
The aim of the present study was to precool cauliflower using forced-air, vacuum and high and low flow hydro cooling methods. The weight of the precooled cauliflower heads (5000±5 g) was measured before they were placed in standard plastic crates. Cauliflower heads, whose initial temperature was 23.5 ± 0.5 ºC, were cooled until the temperature reached at

4. Potencial alelopático de Cyperus rotundus L. sobre espécies cultivadas
Metabótitos secundários produzidos em algumas plantas podem provocar alterações no desenvolvimento de outras plantas ou até mesmo de outros organismos. Neste trabalho, objetivou-se identificar possíveis efeitos alelopáticos de extratos aquosos de folhas de Cyperus rotundus na germinação e no crescimento de plântulas de Brassica campestris, Brassica

5. Potencial fisiológico de sementes de couve-flor
A eficiência da determinação do potencial fisiológico de lotes de sementes é essencial para a obtenção de informações consistentes, permitindo a composição de programas de controle de qualidade de sementes e a obtenção de informações consistentes para a redução de problemas pós-colheita e durante a comercialização. O objetivo desta pesqui

6. Avaliação do potencial fisiológico, métodos de condicionamento e desempenho de sementes de couve-flor (Brassica oleracea L. var. botrytis) durante o armazenamento e em campo / Evaluation of the physiological potential, priming methods and performance of cauliflower (Brassica oleracea L. var. botrytis) seedlots
The objectives of this research were to identify reliable methods to evaluate the physiological potential of cauliflower seeds, verify the relationship between seed physiological potential and field performance, as well as to define a suitable procedure for seed priming and identify efficient drying methods to avoid the possible reversion of beneficial primi

7. Activation Kinetics of NAD-Dependent Malic Enzyme of Cauliflower Bud Mitochondria 1
NAD-dependent malic enzyme (EC 1.1.1.39) was obtained from isolated mitochondria of cauliflower buds (Brassica oleracea L., var. botrytis). The NAD-linked activity is accompanied by a minor NADP-linked activity. Some contaminant NADP-malic enzyme from the supernatant and the plasma membrane is usually present in crude mitochondrial preparations. NAD-dependen

8. An Evaluation of 4-S-Methyl-2-Keto-Butyric Acid as an Intermediate in the Biosynthesis of Ethylene
Stimulation of ethylene production by cauliflower (Brassica oleracea var. botrytis L.) tissue in buffer solution containing 4-S-methyl-2-keto-butyric acid is not due to activation of the natural in vivo system. Increased ethylene production derives from an extra-cellular ethylene-forming system, catalyzed by peroxidase and other factors, which leak from the

9. Microsomal Lyso-Phosphatidic Acid Acyltransferase from a Brassica oleracea Cultivar Incorporates Erucic Acid into the sn-2 Position of Seed Triacylglycerols.
Developing seeds from Brassica oleracea (L.) var botrytis cv Sesam were examined for the ability to biosynthesize and incorporate erucic acid into triacylglycerols (TAGs). Seed embryos at mid-development contained a high concentration of erucic acid in diacylglycerols and TAGs, and substantial levels were also detected in free fatty acids, acyl-coenzyme A (C

10. Zinc Requirement for Stomatal Opening in Cauliflower.
Zn deficiency induced increases in epicuticular wax deposits, lamina thickness, degree of succulence, water saturation deficit, diffusive resistance, and proline accumulation and decreases in carbonic anhydrase activity, water potential, stomatal aperture, and transpiration in the leaves of cauliflower (Brassica oleracea L. var botrytis cv Pusa) plants.
