Abstract
The production of ethylene in the leaves ofSalix viminalis L. increased gradually from May till October. The emanation from the leaves, the main constituent of which was ethylene, inhibited the extension growth and the formation of the dry matter of rye seedlings more or less equally during the whole growing season. This indicates that the effect of ethylene on the growth is not, to any great extent, dependent on its concentration.
Abstract
Stanovili jsme produkci etylénu a jeho fyziologickou účinnost u listů vrby košíkářské v průběhu vegetace od května do října. Tvorba etylénu se během této doby postupně zvyšovala. Fyziologická účinnost emanací listů vrby, která se projevila inhibicí dloužvého růstu i tvorby sušiny klíčních rostlin žita, byla během vegetace víceméně stejná. To nasvědčuje tomu, že účinek etylénu na růst v rozpětí dost značné koncentrace je relativně stejný.
