Abstract

U ovom diplomskom radu je analizirano osam osobina lista vrste Ranunculus acris uzgojene u Botaničkom vrtu u Zagrebu iz sjemenki sabranih s matičnih biljaka jedne populacije iz Gornje Stubice. Kroz 100 dana 60 biljaka je podvrgnuto različitim količinama sunčevog zračenja. Kvantitativni podaci mjerenih osobina dobiveni su prije i poslije izloženosti biljaka intenzivnom sunčevom zračenju / dubokoj zasjenjenosti i statistički obrađeni. Provjera normalne distribucije varijabli provedena je Kolmogorov-Smirnov testom a pojava fenotipske plastičnosti i razvojne varijabilnosti Mann-Whitney testom. Vrijednosti dobivenih izračuna prikazane su histogramima. Ustanovljena je očekivana visoka varijabilnost u dimenzijama i brojnosti mjerenih karakteristika lista, visoka povezanost broja lisnih vrhova sa lisnim vrhovima srednjeg isperka lista kao i visoka povezanost između širine i duljine lista. Najveće korelacije između nekih varijabli prikazane su scatter-dijagramima. Većina karakteristika je normalno distribuirana. Fenotipska plastičnost je ustanovljena za duljinu peteljke lista i brojnost razvijenih listova. Varijabilnost jedinke u vremenu utvrđena je za sve proučavane karakteristike lista.

Abstract (english)

This thesis analyzes the characteristics of eight leaves of Ranunculus acris grown in the Botanical garden in Zagreb, from the seeds collected from parent plants of a population from Gornja Stubica. During 100 days 60 plants were subject to different amounts of solar radiation. Quantitative data of the measured traits was obtained before and after the intense exposure to the sunlight/deep opacity. Afterwards that same data was statistically analyzed. Normal distribution verification of variables was performed using Kolmogorov-Smirnov test while the occurrence of phenotypic plasticity and developmental variability was discovered using the Mann-Whitney test. Values obtained from both calculations are shown in histograms. The following was discovered: there was the expected high variability in dimensions and abundance of measured characteristics of the leaves, the high correlation of number of leaf tops and the middle barb leaf tops, and the high correlation between the width and the length of the leaf. The highest correlations between some variables are shown in scatter-diagrams. Most characteristics are normally distributed. Phenotypic plasticity has been identified for the leaf stalk length and the abundance of developed leaves. Unit variability in time was found for all studied leaf characteristics.
