Propylene uptake by intact pea seedlings (Pisum sativum L. cv. Alaska) was easily detected using standard gas chromatographic techniques suggesting rapid metabolism. Comparative studies with highly purified (14)C(3)H(6) and (14)C(2)H(4) under aseptic conditions verified that propylene was rapidly metabolized and indicated that some aspects of its metabolism were similar to that of ethylene since (14)C(3)H(6), like (14)C(2)H(4) (Beyer, Nature 1975, 255: 144-147), was oxidized to (14)CO(2) and incorporated into water-soluble tissue metabolites. However, (14)C(2)H(6) was metabolized at a substantially faster rate and unlike (14)C(2)H(4) the rate of (14)C(3)H(6) tissue incorporation exceeded its rate of oxidation to (14)CO(2). In addition the neutral (14)C-metabolites derived from (14)C(3)H(6) were chromatographically distinct from those formed from (14)C(2)H(4).
使用标准气相色谱技术很容易检测到完整豌豆幼苗(豌豆品种阿拉斯加)对丙烯的吸收,这表明其代谢迅速。在无菌条件下,用高纯度的(14)C(3)H(6)和(14)C(2)H(4)进行的比较研究证实,丙烯能迅速代谢,并且表明其代谢的某些方面与乙烯相似,因为(14)C(3)H(6)与(14)C(2)H(4)一样(Beyer,《自然》1975年,255卷:144 - 147页)被氧化成(14)CO(2)并掺入水溶性组织代谢物中。然而,(14)C(2)H(6)的代谢速度要快得多,与(14)C(2)H(4)不同,(14)C(3)H(6)掺入组织的速度超过了其氧化成(14)CO(2)的速度。此外,源自(14)C(3)H(6)的中性(14)C - 代谢物在色谱上与由(14)C(2)H(4)形成的代谢物不同。
