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.

Response of cabbage (Brassica oleracea L. var. capitata), Brussels sprouts (Brassica oleracea var. gemmifera) and broccoli (Brassica oleracea L. var italica) to reduced N rates was studied over 4 yr. Treatments were application methods, broadcast, split and banded with two rates of N; 120 and 90 kg ha−1 plus a control of 150 kg ha−1 broadcast N. Marketable yield was lower by 15, 23, and 13%, respectively, compared to the control. Banding lowered yield of cabbage and broccoli. The lower N rate had the lowest yield in all crops. Leaf N concentration varied with N rate. Key words: Broccoli, Brussels sprouts, cabbage, reduced nitrogen, yield

Broccoli (Brassica oleracea L. ssp. italica Plenck., cult Waltham 29), Brussels sprouts (Brassica oleracea L. ssp. gemmifera, cult Jade Cross), and cauliflower (Brassica oleracea L. ssp. botrytis, cult Snowball Y) were grown at four locations on Prince Edward Island with five levels of applied B at each location. The levels of applied B were: 0, 0.56, 1.12, 2.24, and 4.48 kg B/ha. No B deficiency symptoms, with the exception of hollow stem in cauliflower and broccoli, were noted. The incidence of hollow stem in these crops was not affected by applied B. The B concentration of tissues of all three crops was generally lower late in the growing season than earlier. Boron levels in the first tissue samplings were 13–70, 13–101, and 8–97 ppm in broccoli, Brussels sprouts, and cauliflower, respectively, and were found to be in the sufficiency range. A hot-water-soluble B content of 0.34–0.49 ppm in soil was sufficient for optimum growth of the crops. No B toxicity was observed even when the rate of applied B was 4.48 kg/ha.

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. Key words: Eastern Canada, Brussels sprouts yields, field studies, boron

Plant density is an important variable for achieving maximum yields and uniform vegetable maturity. Optimal plant density can be achieved by establishing appropriate distances both between the rows as well as in the rows of plants. The experiment was carried out between 2010–2012 at the experimental field of the Crimean Agrotechnological University in Simferopol, Ukraine. The experiment was established as randomised blocks with four replications. This study aimed to determine the effect of plant density on the growth, development and yield of Brussels sprouts. Increasing the area per plant resulted in a shortening of the time to the beginning of head formation, technical maturity and harvest. In all study years, increasing the distance between plants caused an increase in leaf assimilation area, stalk diameter and the number of heads per plant, however, the height of plants was lower. The most favourable parameters characterising marketable yield were found at an area per plant of 0.56 m<sup>2</sup>, however, the maximum yield from 1 ha (determining the profitability of the cultivation) was found at an area of 0.49 m<sup>2</sup> per plant.
