Abstract

[8-(14)C]Benzylaminopurine (BA) translocation was studied in whole plants of Phaseolus vulgaris L. under three different light regimes (continuous light, 8-hour light + 16-hour dark, dark). Applications were made to the apex, to a cotyledonary leaf, or to the root system. Results showed that no BA basipetal translocation occurred, however BA is easily absorbed by the root system and is translocated acropetally.The amount of BA absorbed and its acropetal translocation rate depend on the light regime. The hypothesis of a passive cytokinin transport through the xylem, regulated by the transpiration stream, is discussed.

摘要

[8-(14)C]苄氨基嘌呤（BA）在三个不同光照条件（连续光照、8 小时光照+16 小时黑暗、黑暗）下，在菜豆属植物的整株植物中进行了转运研究。将其施用于顶端、子叶或根系。结果表明，BA 没有向基转运，但很容易被根系吸收，并向顶转运。吸收的 BA 量及其向顶转运率取决于光照条件。通过木质部被动运输细胞分裂素的假说，受蒸腾流调节，进行了讨论。
