Abstract
Japanski dvornik (Reynoutria japonica Houtt.) invazivna je vrsta s negativnim utjecajem na okoliš i ekonomiju. Cilj ovog rada bio je utvrditi utjecaj režima osvjetljenja na fotosintetsku učinkovitost japanskog dvornika te opisati njegov utjecaj na anatomiju listova. Dvije skupine biljaka uzgajane su pri dva različita svjetlosna režima: konstantno niskom intenzitetu (60 mola m-2 s-1) i promjenjivom (0 - 1250 mola m-2 s-1). Nizak intenzitet svjetlosti doveo je do razvoja tanjih listova u odnosu na biljke uzgajane na promjenjivom intenzitetu svjetlosti. Mjerenjem fluorescencije klorofila a utvrđeno je da su biljke izložene niskom intenzitetu svjetlosti imale niži maksimalni kvantni prinos fotosustava II (TR0/ABS) kao i indeks fotosintetske učinkovitosti (PIABS). Rezultati ovog istraživanja sugeriraju da nizak intenzitet svjetlosti inducira proces senescencije u listovima japanskog dvornika.
Abstract (english)
Japanese knotweed (Reynoutria japonica Houtt.) is an invasive species with a negative impact on environment and economy. The aim of this study was to determine the influence of light regimes on photosynthetic efficiency as well as to describe their effects on leaf anatomy of Japanese knotweed. Two groups of plants were grown under two different light regimes: constant low light intensity (60 mol m-2 s-1) and fluctuating light intensities (0 - 1250 mol m-2 s-1). Low light intensity resulted with the development of thinner leaves compared to those grown under fluctuating light intensity. Measurements of chlorophyll a fluorescence showed that plants exposed to low light intensity have lower maximum quantum yield of primary photochemistry (TR0/ABS) as well as lower photosynthetic performance index (PIABS). The results of this study suggest that low light intensity triggered induced senescence in the leaves of Japanese knotweed.
