abstract = {Honey locust (Gleditsia triacanthos L.), in the past planted as ornamental, technical or forest tree, is presently considered as casually invasive tree in Danube basin. Since plant invasiveness is usually tightly associated with its reproduction biology, in this work we focused on characterization of seeds from honey locust populations across this area. Analysing seed coat colour, thousand seeds weight (TSW), seed projection area, seed thickness, percentage of germinated seeds and their germination energy, as well as portion of seeds infested by honey locust seed beetle (Megabruchidius tonkineus), consumed part of seeds and their germination ability in relation to seed characteristics, local temperature means and precipitation sums during vegetation period, we came to the following conclusions: seed coat colour diversity decreases with geographical latitude; TSW, seed projection area and thickness were negatively correlated to mean temperature and positively to precipitation sum; between percentage of naturally germinated seeds and TSW as well as seed thickness we found positive correlations; germination energy showed positive relation to mean temperature and a negative one to precipitation sum; and the same relations were observed for infested seeds percentage and consumed seed part. No infested seed was able to germinate. From these results we can conclude that in colder and wetter conditions higher seed germinability, and in warmer and drier conditions enhanced germination energy of seeds supports spreading of this tree species.

Honey locust (Gleditsia triacanthos L.), in the past planted as ornamental, technical or forest tree, is presently considered as casually invasive tree in Danube basin. Since plant invasiveness is usually tightly associated with its reproduction biology, in this work we focused on characterization of seeds from honey locust populations across this area. Analysing seed coat colour, thousand seeds weight (TSW), seed projection area, seed thickness, percentage of germinated seeds and their germination energy, as well as portion of seeds infested by honey locust seed beetle (Megabruchidius tonkineus), consumed part of seeds and their germination ability in relation to seed characteristics, local temperature means and precipitation sums during vegetation period, we came to the following conclusions: seed coat colour diversity decreases with geographical latitude; TSW, seed projection area and thickness were negatively correlated to mean temperature and positively to precipitation sum; between percentage of naturally germinated seeds and TSW as well as seed thickness we found positive correlations; germination energy showed positive relation to mean temperature and a negative one to precipitation sum; and the same relations were observed for infested seeds percentage and consumed seed part. No infested seed was able to germinate. From these results we can conclude that in colder and wetter conditions higher seed germinability, and in warmer and drier conditions enhanced germination energy of seeds supports spreading of this tree species. However, honey locust seed beetle can significantly affect seed germinability in regions with warm and dry summers. |

a large variability in percentage of leaves longer than 70 mm (16–58%) and those of dark-green
colour (28–78%), portion of half-full flowers (0–6%) and those of intense pink colour (0–100%),
and percentage of hips longer than 20 mm (0–45%) and those of intense red colour (18–48%),

eutric cambisols in Modra – Pažite, haplic luvisols on loess in Vrbové – Baraní dvor, and rendzic/
chromi-rendzic leptosols in Zobor – Lyžiarska lúka (increasing soil quality from stand to stand).
Leaves and flowers grew in conditions of average temperature 15.3 °C (Modra – Pažite and Zobor
– Lyžiarska lúka) and 14.5 °C (Vrbové – Baraní dvor). Precipitation ranged from approximately
300 mm in Modra – Pažite to 400 mm in Zobor – Lyžiarska lúka. Average temperature for hip
formation varied from Zobor – Lyžiarska lúka (19.6 °C) to Modra – Pažite (20.4 °C). In this period,
precipitation sum was round 200 mm in Zobor – Lyžiarska lúka and approximately 250 mm in the
rest two stands. Quantitative traits of all dog roses were generally less correlated to genome size
and environmental factors. However, in R. canina genotypes, leaf length was determined mainly
by genome size (r = 0.437) and temperature (r = –0.316), and leaf colour by temperature (r = 0.777)
and precipitation (r = 0.557), flower richness only by temperature (r = –0.320), flower colour by
temperature (r = 0.606) and soil quality (r = –0.559), and hip colour was defined mainly by
precipitation (r = 0.588), then by temperature (r = 0.427) and genome size (r = –0.362); but
no factor had important influence on hip length. We can conclude that except for leaf size, all
analysed quantitative traits were mainly determined by environmental factors.},
