Foliar application may be used to supply boron (B) to a crop when B demands are higher than can be supplied via the soil. While B foliar sprays have been used to correct B deficiency in sunflower (Helianthus annuus L.) in the field, no studies have determined the amount of B taken up by sunflower plant parts via foliar application. A study was conducted in which sunflower plants were grown at constant B concentration in nutrient solution with adequate B (46 mum) or with limited B supply (0.24, 0.40 and 1.72 mum) using Amberlite IRA-743 resin to control B supply. At the late vegetative stage of growth (25 and 35 d after transplanting), two foliar sprays were applied of soluble sodium tetraborate (20.8 % B) each at 0, 28, 65, 120 and 1200 mm (each spray equivalent to 0, 0.03, 0.07, 0.13 and 1.3 kg B ha(-1) in 100 L water ha(-1)). The highest rate of B foliar fertilization resulted in leaf burn but had no other evident detrimental effect on plant growth. Under B-deficient conditions, B foliar application increased the vegetative and reproductive dry mass of plants. Foliar application of 28-1200 mm B increased the total dry mass of the most B-deficient plants by more than three-fold and that of plants grown initially with 1.72 mum B in solution by 37-49 %. In this latter treatment, the dry mass of the capitulum was similar to that achieved under control conditions, but in no instance was total plant dry mass similar to that of the control. All B foliar spray rates increased the B concentration in various parts of the plant tops, including those that developed after the sprays were applied, but the B concentration in the roots was not increased by B foliar application. The B concentration in the capitulum of the plants sprayed at the highest rate was between 37 and 93 % of that in the control plants. This study showed that B foliar application was of benefit to B-deficient sunflower plants, increasing the B status of plant tops, including that of the capitulum which developed after the B sprays were applied.

This paper examines 116 articles related to sexual and reproductive health translated into English from the Khmer press from April 1997 to February 2004. These excerpts were found in The Mirror, a publication of the non-governmental organisation Open Forum of Cambodia, which collates Grid reviews all issues of the Khmer press on a weekly basis. Five major themes were identified: the politics of women's health, government regulation and control, the sex industry in Cambodia, rape, and the HIV epidemic. Discourse analysis of these articles in the context of other sources and experience allows a gendered exploration of the reporting of sexual and reproductive health and rights issues in Cambodia by the Khmer print media. The reports explore the contested political empowerment of women in this strongly hierarchical society, and the mechanisms used to regulate and control sexual activity. The expanding sex industry and associated sexual trafficking ore reported, together with the corruption of legal structures designed to regulate health systems and protect women and children from sexual exploitation and rope. The growing problem of AIDS and successes in reducing HIV transmission through the collaboration of sex workers in the 100% condom use policy is documented, and the tensions implicit in G Cultural representation of women that both protects and constrains women ore explored.
