15 صفحه اولAuxin transport and conjugation in cotton explants.
Indoleacetic acid (IAA), a naturally-occurring auxin, prevents or retards abscission of plant parts under many conditions (1). When applied to the cotyledonary petiole stumps of explants of cotton (Gossypium. hirsutum L.) in a commonly used abscission test IAA in moderate physiological coIncentrations retards abscission markedly (2, 6). The disposition within the explant of the auxin applied un...
متن کاملTransport of the Auxin 2,4-Dichlorophenoxyacetic Acid Through Absiccion Zones, Pulvini, and Petioles of Phaseolus vulgaris.
Measurements were made of the transport of 2,4-dichlorophenoxyacetic acid-(14)C (2,4-D) through segments cut from the region of the distal abscission zone in young and old primary leaves of Phaseolus vulgaris L. When old leaves were used basipetal transport of 2,4-D in segments including pulvinar tissue, abscission zone, and petiolar tissue was much less than in wholly petiolar segments. In bot...
متن کاملTransport of the Auxin, Picloram, Through and Coleus and Stem Sections of Petioles of Bean Pea
The transport of the synthetic auxin, picloram (4-amino-3,5,6-trichloropicolinic acid) was investigated in sections of petioles of Phaseolus vulgaris L. and Coleus blumei Benth. and stems of Pisum sativum L. Transport of 14C-picloram was basipolar in all tissues, although the degree of polarity was dependant on age. The velocity of picloram movement was calculated at between 0.75 and 1.11 mm/hr...
