SOME PHYSIOLOGICAL AND BIOCHEMICAL CHANGES DURING FLOWER DEVELOPMENT AND SENESCENCE IN Lilium aziatische CV. FABRUANO
Faculty of Agriculture, AI-Azhar University, Cairo.
Abstract
Some physiological and biochemical changes accompanying lily (Lilium aziatische cv. Fabruano) during flower development and senescence were monitored.Flower development and senescence were categorized into 12 stages, each separated by 2 day. Flower F.Wt and O.wt increased as flowers developed (stages 1 to 5) and opened (stages 6 to 8) and then declined with senescence (stages 9, to 12),also bud length increased gradually and reaching maximum before opening at (stage6). When flowering stems placed in water directly after harvest (stage 4 or colored . buds), the first visible symptom of senescence in flowers is petal in- rolling, of the "out petal" after about 10 days, followed by "in petal" in rz" day and petal wilting in 16th day. Total soluble sugars and reducing sugars in the petal tissue increased as flower opening was completed and then declined. The protenious amino acids content decreased gradually throughout flower development and senescence, whereas phenolics concentration were decreased followed by an increasing trend with development and senescence (especially at stages 11 and 12).
