متن کاملInteractions of microtubule disorganizers, plant hormones, and red light in wheat coleoptile segment growth.
Growth response of coleoptile segments excised from 3-day-old seedlings of wheat (Triticum vulgare cv. Baart) to gibberellic acid, indoleacetic acid, and 2,4-dichlorophenoxyacetic acid, to red light, and to several microtubule disorganizers depends on the initial position of the excised segment in the intact coleoptile. Red light, 660 nm, stimulates the growth of the apical cells, but inhibits ...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولRed light and auxin effects on rubidium uptake by oat coleoptile and pea epicotyl segments.
Apical segments of etiolated oat (Avena sativa L. cv. Victory) coleoptiles showed enhanced uptake of [(86)Rb(+)] when tested 30 minutes after a 5-minute red irradiation. The response was partly reversible by far red light. Uptake was sensitive to carbonyl cyanide m-chlorophenyl hydrazone, but not to isotonic mannitol. Indoleacetic acid (10(-7) molar) caused a very pronounced and rapid stimulati...
