Abstract
Germination ofPinus banksiana seeds is controlled by the photoreversible phytochrome reaction. The seeds, even unimbibed, are sensitive to red light. At 660 nm, the energy required to promote germination to the same order of magnitude is much higher for unimbibed seeds than for the imbibed ones. In both cases it is possible to reverse the effect of a single red light irradiation by applying far red light (730 nm).
Abstract
Klíčení uPinus banksiana je kontrolováno fotoreverzibilní fytochromovou reakcí. U suchých i namáčených semen je klíčení vyvoláno červeným světlem (660 nm). Energie ozáření nezbytná pro daný stupeň klíčení je daleko vyšši u suchých semen. V obou případech je možno účinek jednorázové aplikace červeného světla zrušit ozářením v oblasti dlouhovlnného červeného záření (730 nm).
