Endogenous Gibberellins in Developing Apple Seeds in Relation to Alternate Bearing
Tu, Yicheng, M.S., Purdue University, December, 2000. Endogenous Gibberellins in Developing Apple Seeds in Relation to Biennial Bearing. Major Professor: Peter M. Hirst. It is believed that Gibberellins (GA) produced in apple seeds act as an inhibitory signal to flower induction in the neighboring buds. As an exception, GA4 is not inhibitory and sometimes found to be promotive to apple flowerin...
متن کاملVariations in endogenous gibberellins in developing bean seeds I. Occurrence of neutral and acidic substances.
Activities of separated and chromatographed substances in the nonacidic, acidic ethyl acetate and acidic butanol fractions from bean seeds, Phaseolus vulgaris L., cv. Bountiful and Kentucky Wonder, were measured in the Progress No. 9 dwarf pea bioassay grown under red light. Activity in the nonacidic fraction was shown to be attributable only to neutral substances and was free of acidic gibbere...
متن کاملVariations in Endogenous Gibberellins in Developing Bean Seeds II. Changes Induced in Acidic and Neutral Fractions by GA(1).
Immature (8-mm), medium mature (11-mm), and mature green (16- and 17-mm) bean seeds (Phaseolus vulgaris L. cv. Kentucky Wonder and Bountiful) were incubated in gibberellin A(1) solutions for 24 hours at 20 degrees . Extracts from the seeds were separated into nonacidic, acidic ethyl acetate, and acidic butanol fractions. These were chromatographed. The eluates of the chromatograms were tested o...
متن کاملGibberellins and parthenocarpic ability in developing ovaries of seedless mandarins.
Satsuma (Citrus unshiu [Mak] Marc.) and Clementine (Citrus reticulata [Hort.] Ex. Tanaka, cv Oroval) are two species of seedless mandarins differing in their tendency to develop parthenocarpic fruits. Satsuma is a male-sterile cultivar that shows a high degree of natural parthenocarpy and a high fruit set. Seedless Clementine varieties are self-incompatible, and in the absence of cross-pollinat...
متن کاملDetermination of Amygdalin in Apple Seeds, Fresh Apples and the Processed Apple Juices 2
6 7 8 9 Abstract 10 Cyanogenic glycosides are natural plant toxicants. Action by endogenous plant enzymes 11 can release hydrogen cyanide causing potential toxicity issues for animals including 12 humans. We have quantified amygdalin in seeds from different apple varieties, determined 13 the effects of processing on the amygdalin content of apple juice and quantified amygdalin 14 in commerciall...
