Brassica Oleracea L

Boron application rates as high as 8 and 16 kg ha−1 were not toxic to Brussels sprouts (Brassica oleracea L. ssp. gemmifera). These rates resulted in leaf tissue B levels of 123 and 161 μg g−1 and of 7.6 and 9.1 μg HWS B g−1 soil, respectively. Rates of 8–16 kg B ha−1 would, however, be seriously toxic to many crops. It is therefore strongly recommended that rates of B applied to Brussels sprouts should not exceed 2 kg ha−1. Such B applications should eliminate B deficiency in most crops and would not pose a threat of B toxicity to crops grown in the following year.

Maximizing yield and quality of processing broccoli (Brassica oleracea L. var. italica) is critical to successful production in Atlantic Canada. Field studies were conducted from 2004 to 2006 to evaluate the effect of plant density and trickle irrigation on the yields and incidence of hollow stem for early and late transplanting of broccoli. Treatments consisted of five plant densities ranging from 3.17 to 6.35 plants m–2. Each plant density was either not irrigated or trickle irrigated to maintain at least 25 mm total precipitation per week. The highest marketable yield was achieved at 5.56 plants m–2 when grown in an early transplanting with trickle irrigation in a single row with 90 cm between the row and 20 cm within the row. Overall, earlier transplanting dates were more productive. Trickle irrigation increased marketable yield by an average of 12% over the 3 yr of tests. Average head weight, head diameter, and the incidence of hollow stem decreased as plant density increased. Leaf tissue N was not affected by plant density, trickle irrigation or transplanting date.Key words: Brassica oleracea L. italica, plant density, yield, growth

AbstractAgeing causes a delay in the onset of DNA replication in seeds. Aerated hydration for 8 h, a treatment to invigorate seeds, resulted in a reduction of about 12 h in the time difference in the onset of DNA synthesis between unaged and aged embryos of brassica seed. This effect is consistent with a recovery process occurring during aerated hydration of the seed involving the repair of accumulated DNA damage. The occurrence of hydroxyurea-resistant 3H-thymidine incorporation in aged Brussels sprouts embryos during the period 16–32 h from the start of hydration supports this interpretation.

Soil Potassium

Brussels sprouts (Brassica oleracea var. gemmifera DC., Jade Cross) require no potassium fertilizer on Prince Edward Island soils if exchangeable soil K as determined by neutral 1 N ammonium acetate exceeds 100 ppm. Below 75 ppm exchangeable soil K, 186 kg K/ha must be applied for maximum yields. Potassium treatments increased yields at only three of 12 locations studied. Leaf tissue potassium concentration was significantly increased at all locations by the fertilizer treatments. Neutral 1 N ammonium acetate for determining exchangeable K was the best soil analysis extract among those tested for measuring available potassium. Tissue analysis gave no information beyond soil analysis for predicting potassium fertilizer requirements on any soil studied.

Glucosinolate Concentration

Glucosinolates (GSL) are bioactive compounds found in cruciferous vegetables that have been shown to have chemopreventive benefits for human health. The objective of this study was to determine whether foliar application of jasmonic acid (JA) increases glucosinolate accumulation and yield in cabbage (Brassica oleracea L. Capitata group). Field studies were conducted in 2004 and 2005 with a green (‘Quisto’) and red (‘Ruby Perfection’) cabbage cultivar. Foliar JA application rates were 0.1 mm, 0.2 mm, and split application of 0.2 mm JA with surfactant, surfactant control, and water control. Yield of both cabbage cultivars was not changed by JA application in both years of the study. In both years, ‘Ruby Perfection’ had significantly higher glucosinolate concentrations than ‘Quisto’ with sinigrin being the predominant glucosinolate in both varieties. JA application consistently increased sinigrin, gluconapin, and glucoiberin concentrations across cultivars and years of the study. JA application also increased progoitrin and total GSL concentrations, but the effect was inconsistent between years and cultivars. In most cases, a split application of 0.2mm JA resulted in the highest GSL accumulation. GSL accumulation was significantly higher in 2005 than 2004 for both cultivars. Climatic data suggest that annual differences in temperature may have influenced the variability in glucosinolate concentration in cabbage.

Brassica Oleracea L

The potential to produce broccoli (Brassica oleracea L. spp. Italica Plenck 'Green Valiant' and 'Emperor') at high latitudes was evaluated by measuring yield, head size and incidence of hollow stem in plantings at two sites and eight spacings. The maximum yield of individual heads for fresh market was obtained at a spacing of 45 × 30 cm using single plant transplants. At this spacing, yields for Green Valiant and Emperor were 18.3 and 15.0 MT ha−1, respectively. Broccoli heads small enough to be used for processing were obtained at a spacing of 45 × 40 cm using two plants per transplant plug with yields of 21.4 MT ha−1 for Green Valiant. These yields were compared with published studies and it was concluded that there was no effect of latitude on broccoli yields or head weights. The incidence of hollow stem was low in Alaska and occurred in Green Valiant planted at wide spacings. Only plants that produced heads with the largest mean weights and mean diameters exhibited hollow stem. The use of multiple plants per transplant plug decreases mean head weight and diameter and reduces the incidence of hollow stem.

The effects of various rates of nitrogen, phosphorus, and potassium on the boron concentration of leaf tissue of cauliflower (Brassica oleracea var. botrytis L. ’Snowball Y’), Brussels sprouts (Brassica oleracea var. gemmifera Zenker ’Jade Cross’) and peas (Pisum sativum L. ’Dark Skin Perfection’) were investigated at several locations in Prince Edward Island. Except for N on cauliflower, B concentrations of leaf tissues of these crops were not greatly affected by the N, P, or K treatments. Applied N increased the B concentration of cauliflower leaf tissue at eight of the nine locations investigated.
