Lettuce seed, germination

The accumulated assay results obtained with the 4-alkyl-2-methylpyrrolo[2,3-d]pyrimidines are of special interest. Can-pounds 25 and 26 exhibited significant cytokinin activity in all assays utilized. On the other hand, compound 27 was a potent antagonist in the tobacco bioassay but had little activity in the other two assay systems, while 29 acted as an anticytokinin in the tobacco bioassay and a cytokinin in the lettuce seed germination assay, but was without activity in the Amaranthus test system. [Pg.92]

The 3 -position of ABA can also be modified while maintaining bioactivity. We synthesized 3 -azido-ABA (5) from ABA via 2 a,3 a-dihydro-2 a,3 a-epoxy-ABA [26]. The biological activity of 5 was equivalent to that of ABA in the inhibition of lettuce seed germination. An investigation of the photosensitivity of 5 is now in progress. [Pg.331]

A lettuce seed germination stimulant, graphinone, isolated from Graphium fungus culture has been attributed the structure (114). This compound appears to be identical to ovalicin, isolated from Pseudeurotium ovalis. ... [Pg.71]
