“…The rapid reduction of TL and "glycerides" witlh germination is a well established fact in fatty angiosperm seed (3,9,19,26) as well as in other lots of Douglas fir seed (6,7). Apparently it is a common pattern in the germination of seed with fats as the major reserve.…”

“…The amounts of this fatty material, which showed slight increases during the first 24 hours and after longer periods an insignificant small loss (Table 1), are supported by the findings of Riider-Roitzsch (1957) in the same species, which showed a small loss of "Fettes 01" after a germination for 2 days under optimal conditions and a rapid consumption first during the period 4-9 days after the start of the imbibition. However, the observed increases of extractable material during the first 24 hours possibly connects the seeds of Scots pine to the last one of the three different types of fatty seeds, which respectively show: an immediate decrease, at first no dcrease or at first a slow increase of the fat material during the germination jjrocess (Zeller 1957). The lighl factor, which controls the germination in this species (Nyman 1963), was neither reflected in the mobilisation of Ihe fats nor in its fatty acid composition (Table 2).…”

The aim of the present investigation has been to study whether the light factor influences the fat metabolism in the scots pine seeds in any way which could be correlated with its effect on the germination. The studies have been made on petroleum ether extracts. Gravimetric determinations showed small increases of extractable material during the first 24 hours of the germination process. After a longer time there was a small but insignificant consumption (72 hours). No effects of the light factor could be found. Investigations with gas‐liquid chromatography on the corresponding extracts did not reveal any influence on the fatty acid composition, either of the light factor or of the germination period. The main identified fatty acids were linoleic, oleic, palmitic and stearic acid. One of the unidentified components (“c”) was also present in a large amount. Principally the same acids were found as free fatty acids but in different proportions: oleic, palmitic, linoleic and stearic acid. After the onset of the imbibition the linoleic acid appeared in the largest proportion. The total content of free fatty acids increased with increasing germination period. This was found both in titration experiments and in gas‐liquid chromatography with an internal standard. The latter method permitted studies on the content of the individual acids. During the period 0–21 hours there were no evident differences between the content in light‐ and dark‐germinated seeds, during the period up till 48 hours there was lower content in the light‐germinated seeds concomitant with the onset of the mitotic activity in these seeds and after 48 hours there was a rapid increase in the same ones corresponding to the opening of the seed coats and the incipient protrusion of the rootlets. Thus changes of free fatty acid content were found only after the start of the light‐induced growth but not under the preliminary phase, which earlier has been shown to be the determinative one in the light control of the germination.
