Effect of Asahi SL on China aster ‘Aleksandra’ seed yield, germination and some metabolic events

  • Krzysztof Górnik
  • Mieczysław Grzesik


The effects of Asahi SL (sodium ortho and para-nitro phenolate, sodium 5 nitro guaiacolate) sprays on China aster plant height, seed yield and some metabolic events were investigated. The plants were sprayed with Asahi SL, in concentration of 0, 0.1, 0.2 or 0.4 %, three times before or during flowering, and six times before and during this stage. It was found that Asahi SL applied three times during flowering brought about an increase in the seed yield, germination and metabolic activity and did not modify vegetative growth of plants. The chemical used earlier, before flowering, had detrimental effect on seed yield and quality, although it stimulated vegetative growth. The positive effect of Asahi SL was more prominent in weather conditions unfavourable for seed production.
