Brassica Oleracea L

A canola (Brassica napus L. var oleífera) é uma oleaginosa, pertencente à família Brassicaceae, resultado do cruzamento interespecífico entre repolho silvestre (Brassica oleracea L.) e mostarda (Brassica rapa L., syn. campestris). O boro é considerado um micronutriente, que atua na translocação de açúcares, formação de proteínas, crescimento do tubo polínico, germinação dos grãos de pólen, desenvolvimento das sementes e das paredes celulares. O objetivo desta pesquisa foi estudar as interferências nos componentes produtivos de dois híbridos de canola com a aplicação de adubação com boro por via foliar. Para tanto, instalou-se um experimento em condições de campo num delineamento experimental de blocos ao acaso em arranjo fatorial 2 x 3. Utilizou-se os híbridos Hyola 433 e Hyola 575 CL e três doses de boro foliar (0;100; 200) g ha-1 de B. As seguintes características foram avaliadas:  número de plantas, número de síliquas por planta, massa de parte aérea, massa de 100 grãos e produtividade. Com a aplicação de boro houve aumento da massa de grãos independente do híbrido. Para produtividade houve aumento somente para o híbrido Hyola 433, sendo a maior produtividade alcançada na dose de 200 g ha-1. O híbrido Hyola 575 CL não teve sua produtividade alterada com a aplicação de boro. Palavras-chave: ácido bórico; Brassica napus L. var. oleífera; colza; massa de 100 grãos; oleaginosa.   Leaf boron fertilization in two rapessed   ABSTRACT: Rapessed (Brassica napus L. var oleífera) is an oilseed, belongs to Brassicaceae family, resultated between inter specific crossing of wild cabbage (Brassica oleracea L.) and mustard (Brassica rapa L., syn. campestris). Boron is considered a micronutrient, acting in sugars translocation, protein formation, pollen tube growth, pollen grain germination, seeds and cell wall development. The aimed was to study the interferences in productive components of two rapessed hybrids with application of boron fertilization by leaf application. For this, a field experiment was installed by using experimental design of randomized blocks in a 2 x 3 factorial scheme.  Hyola 433 and Hyola 575CL hybrids and three doses of leaf boron (0; 100 and 200) g ha-1 of B were used. The following characteristics were evaluated: plants number, number of pods per plant, mass of one hundred grains and yield. With boron application there was an increase in grain mass independent of the hybrid. In relation grain yield there was increase only for Hyola 433 hybrid, with the highest yield reached at 200 g ha-1. The Hyola 575CL hybrid did not have its productivity altered with the application of boron. Keywords: boric acid; Brassica napus L. var. oleífera; mustard; mass of a hundred grass; oilseeds.

Ad Libitum

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.

Brassica Napus L

An improved protocol for Brassica protoplast culture and plant regeneration was developed. Isolated protoplasts from four-weeks-old in vitro shoot tip culture of Brassica oleracea var. botrytis cv. Siria F1 and Brassica napus doubled haploid of breeding line OP-1 were cultured at a density of 9.8&ndash;11.2 &times; 10<sup>4 </sup>protoplasts/ml in darkness at 25&deg;C in a modified medium containing 2% glucose, 0.25 mg/l 2,4-D, 1 mg/l BAP and 1 mg/l NAA. The first divisions of protoplasts were observed on the third day of culture in B. oleracea and on the fourth day in B. napus. The protoplast cultures were diluted with low osmotic medium on 7<sup>th</sup> and 11<sup>th</sup> day. The frequency of dividing cells was about 80% in B. oleracea and 50% in B. napus. After one month, the microcalli of approximately 0.5&ndash;1 mm in size were transferred into an induction medium with various combinations of growth regulators. Minimum duration of enzyme treatment time and extended dark period in the initial phase of culture increased the survival rate of protoplasts. Organogenesis started when the calli enlarged in size on an induction medium (1 mg/l NAA, 0.02 mg/l GA<sub>3</sub>, 1 mg/l 2iP) with 2% sucrose and 0.8% agar. Regeneration frequency of calli was found to be 69&ndash;75% in B. oleracea and 2&ndash;3% in B. napus. Well-developed shoots were transferred for rooting to a half-strength MS medium without growth regulators. More than 100 B. oleracea regenerants were transferred into soil, and they produced normal heads and set seeds. This very simple procedure is efficient and suitable mainly for B. oleracea var. botrytis and represents a background for fusion experiments. &nbsp;
