Prohexadione-Ca, an acylcylohexadione, is a plant growth retardant jointly developed by BASF, Germany and Kumiai Chemical Industry, Japan. In 2012, a trial on 11-year-old 'Aroma'/'M 9' apple trees growing on the experimental farm at NIBIO Ullensvang, western Norway was initiated. Trees were treated with prohexadione-Ca (trade name Regalis®, 10% prohexadione-Ca as active ingredient) 10 days after full bloom (June 6) at concentrations of 125 or 250 g ha-1; other trees were also sprayed 10 days after full bloom and again one month later (July 5) at the same concentrations and compared against an untreated control. Treatments were applied to individual whole trees in a randomized complete block design with four replications. Prohexadione-Ca treatments significantly reduced shoot growth of treated apple trees. Two treatments with 125 g or one treatment of 250 g reduced growth by ~80%. Prohexadione-Ca had little effect on yield and fruit quality. Shoot growth was also retarded in the year following application and this is attributed to a carry over effect of the prohexadione-Ca application(s).
Abstract
Swede is a root vegetable grown under a range of growth conditions that may influence the product quality. The objective of this controlled climate study was to find the effect of growth temperature on sensory quality and the contents of glucosinolates, vitamin C and soluble sugars. High temperature (21 °C) enhanced the intensities of sensory attributes like pungent odour, bitterness, astringency and fibrousness, while low temperature (9 °C) was associated with acidic odour, sweet taste, crispiness and juiciness. Ten glucosinolates were quantified, with progoitrin as the dominant component followed by glucoberteroin, both with highest content at 21 °C. Vitamin C also had its highest content at 21 °C, while the total sugar content was lowest at this temperature. In conclusion, the study demonstrated clear effects of growth temperature on sensory quality and some chemical properties of swede and indicated a good eating quality of swedes grown at low temperatures.
