Abstract

Cilj rad bio je utvrditi pedološka svojstva tla te morfološku i kemijsku varijabilnost plodova pitomog kestena na području Zrinske gore. Uzorci za istraživanja sakupljeni su na području UŠP Sisak, Šumarija Hrvatska Kostajnica u G.J. Šamarica I, u četiri odjela/odsjeka različitog načina gospodarenja. U svakom odjelu/odsjeku sakupljen je kompozitni uzorak tla s dubine od 0 do 10 cm ispod 20 stabala, s kojih je sakupljeno minimalno 100 plodova za morfološka i kemijska istraživanja. Plodovi su obrađeni standardiziranim morfometrijskim metodama, a na svim uzorcima je određen i udjel vode, pepela, masti i škroba. Nadalje, na svim uzorcima tla određen je granulometrijski sastav, zatim pH reakcija tla i udio organskog i ukupnog ugljika te ukupnog dušika suhim spaljivanjem. U istraživanim odjelima/odsjecima tekstura tla kreće se u rasponu od praškaste ilovače do praškaste glinaste ilovače. pH-vrijednost u H2O kreće se u rasponu od 4,96 do 5,25, a u CaCl2 u rasponu od 3,90 do 4,29. Drugim riječima, tla na istraživanom području su vrlo jako do jako kisela. Morfometrijskom analizom je utvrđeno da se na osnovi morfologije plodova odjeli/odsjeci i stabla unutar odjela/odsjeka statistički značajno razlikuju. Nasuprot tomu, za kemijski sastav plodova nisu utvrđene statistički značajne razlike između odjela/odsjeka. Morfometrijskim i pedološkim analizama je utvrđeno da se od četiri istraživana odjela/odsjeka izdvaja odjel/odsjek kojeg karakterizira mezofilnije stanište, fitocenološka zajednica Aposeri foetidae-Castanetum sativae, s nešto višom pH-vrijednošću tla i drugačijom teksturnom oznakom tla (veći udjel frakcije pijeska i manji gline) te nešto krupnijim plodovima.

Abstract (english)

The aim of this study was to determine the pedological properties of
the soil and the morphological and chemical variability of sweet
chestnut fruits in the area of Zrinska Gora. Samples for research were
collected in the area of UŠP Sisak, Šumarija Hrvatska Kostajnica in
M.U. Šamarica I in four sections with different management methods.
In each section, a composite soil sample was collected from a depth
of 0 to 10 cm under 20 trees, from which a minimum of 100 fruits
were collected for morphological and chemical analysis. The fruits
were processed using standardized morphometric methods, and the
mass fractions of water, ash, fat and starch was determined on all
samples. Furthermore, the granulometric composition was
determined on all soil samples, followed by the pH reaction of the soil
and the proportion of organic and total carbon and total nitrogen by
dry burning. In the investigated sections, the soil texture ranges from
powdery loam to powdery clay loam. The pH value in H2O ranges
from 4,96 to 5,25, and in CaCl2 from 3,90 to 4,29. In other words, the
soils in the researched area are very strongly to very acidic. Through
morphometric analysis, it was determined that the sections and the
trees within the sections differ significantly on the basis of the
morphology of the fruits. In contrast, no statistically significant
differences were found between the sections for the chemical
composition of the fruits. Through morphometric and pedological
analyses, it was determined that the section that stands out the most
is the one characterized by mesophilic habitat, the phytocenological
community Aposeri foetidae-Castanetum sativae, with a slightly
higher pH-value of the soil and a different textural mark (larger
proportion of the sand fraction and smaller of clay) and slightly larger
fruits.
