Abstract

U ovom radu istraživanje je provedeno na presadnicama rajčice (Lycopersicon
esculentum Mill.) postavljenih u četiri grupe. Grupe su podijeljene prema planiranim
tretmanima pokusa: mikoriza navodnjavano, mikoriza nenavodnjavano, bez mikorize
navodnjavano i bez mikorize nenavodnjavano. Temperatura je mjerena pomoću termoparova
i infracrvene kamere. Na presadnicama su provedena mjerenja fizikalnih i bioloških
svojstava: vodni potencijal lista, klorofil, dušik, fotosinteza. Različite varijante navodnjavanja
pokazala su različite učinke na svojstva presadnica i to: mikorizirano navodnjavana varijanta
ima najveću masu nadzemnog dijela, lista i stabljike. Najveća temperatura lista je zabilježena
kod tretmana pod vodnim stresom. Zaključeno je da temperatura lista presadnica izmjerena
infracrvenom kamerom može ocijeniti vodni stres presadnica rajčice.

Abstract (english)

The research in this paper was carried on tomato seedlings (Lycopersicon esculentum Mill.)
divided into four groups. Groups were divided according to the planned experiments’
treatment: mycelium irrigated, mycoplasma unirrigated, without mycorrhizae irrigated and
without mycorrhizae unirrigated. The temperature was measured by thermocouples and
infrared cameras. Measurements of physical and biological properties were carried out on
leaflets: water potential of the leaf, chlorophyll, nitrogen, photosynthesis. Different variants
of irrigation have shown different effects on the characteristics of the seedlings: the
michorized irrigated variant has the largest mass of the overhead particle, leaf and stem. The
highest temperature of the leaf was recorded during the treatment under water stress. It is
concluded that the leaf temperature of the seedlings measured by an infrared camera can
assess the water stress of tomato seedlings.
