“…In fact, some authors have even demonstrated the presence of growth substances which could be detected by color reactions characteristic for indole compounds at a slightly different RF from that of IAA in tissues of several pine species (Ogasawara, 1961a(Ogasawara, , b, 1966Ogasawara andKondo, 1962, 1963) and also in other plants (Cutler and Vlitos, 1962). In view of the present studies, the possibility that resin might be responsible for this difference in RF cannot be excluded.…”

“…Ten coleoptiles were added to each test tube and the tubes were then placed in a roller-tube apparatus, rotated at 0.25 rpm for 24 h at 22 °C in the dark. Coleoptile lengths were measured by projecting their images (X3) from a photographic enlarger (Cutler and Vlitos, 1962). Orlandin and kotanin (obtained from A. clauatus) were assayed at 10™3,10"4, 5, and KL6…”

many trees were diseased, no gross anatomical or physiological differences were observed on leaves infected with A. niger. Nevertheless, the organism was examined for plant growth regulator metabolites. Subsequent isolation and extraction of the fungus, from shredded wheat cultures, yielded a crystalline metabolite that inhibited the growth of etiolated wheat coleoptile sections. The metabolite, when compared with the plant growth inhibitor (±)-abscisic acid was as active at 10™3 and 10™4 M in the coleoptile bioassay, but was less active at 10"5 M. (+)-Abscisic acid has been found in many higher plants (Addicott and Lyon, 1969;Milborrow, 1974) and was initially isolated from immature cotton fruits, Gossypium hirsutum L. (Ohkuma et al., 1963) and sycamore leaves, Acer pseudoplatanus L. (Cornforth et al., 1965). Chemical and physical analyses showed that the new metabolite was bis [8,8'-(7-hydroxy-4-methoxy-5-methylcoumarin) ] which we have given the trivial name orlandin (I) (Figure 1).The simple coumarins have shown a wide range of growth regulating responses in plants from growth promotion to growth inhibition depending on the plant species or plant part treated (Mayer and Poljakoff-Mayber, 1961).

“…were carried out under a green safelight (Nitsch and Nitsch, 1956). After incubation, the coleoptiles were placed on a glass plate, and their images (X3) were projected, measured (Cutler and Vlitos, 1962), and statistically analyzed (Kurtz et al, 1965). Dihydropergillin (I) was assayed at 10~3, 10"4, 10"5, and 10~® M by formulating a stock solution, at 10"3 M, in which an appropriate amount of the metabolite was dissolved in 50 /uL of acetone and made to 10 mL with buffer (Cutler, 1968).…”
