Abstract Several studies have shown that petiole xylem structure could be an important predictor of leaf gas exchange capacity, but the question how relates to under different environment conditions remains unresolved. Moreover, knowledge amount and structural variation exists within a single species is also limited. In this study, we investigated intraspecies coordination traits in 2-year-old seedlings Ulmus laevis Pall. well-watered drought conditions. It was found all studied elm were...
The paper analyses the influence of an extended period cold stratification on germination capacity, emergence rate and yield seedlings in Douglas fir as well morphological parameters one-year-old seedlings. A total ten seed lots were used for evaluating originating from Czech Republic, Slovakia, France USA. Germination analysed two provenance beds settings a forest tree nursery. Tested variants involved (a) no pre-sowing treatment, (b) stratified 21 days, (c) 49 days. capacity was higher...
In 2013 -2016, the growth and post -planting losses were monitored of bare -rooted containerized planting stock European beech, Norway spruce Douglas fir together with course weather in seven regions Czech Republic, most endangered by drought.Precipitation deficits occurred especially spring period 2015 summer 2016, significant drought spells being recorded also periods years 2015.If there is a normal after planting, exhibits better growth.If followed severe drought, both dies, more so.The...
Not only in the Czech Republic there is a problem with low yield of Douglas fir seedlings forest tree nurseries. It can be caused mainly by two factors: type pre-sowing treatment and temperature at time sowing. The aim this study to find out their influence on emergence rate fir. We have tested one specific seed lot originated from subject following variants treatment: soaking for 48 hours, stratification without medium 21 days 30 after hours medium. treated seeds were sown phytotron...
Despite the great diversity in leaf structural and physiological traits, traits appear to be coordinated with function. It was observed that petiole xylem structure is an important predictor of gas exchange capacity, yet only a few studies have dealt directly question how relates exchange. An understanding amount variation exists within single species also limited. In this study, we investigated intraspecies coordination two-year old seedlings Ulmus leavis Pall. during optimal drought...
The Douglas fir has been cultivated in Europe since the mid-19th century, but its artificial regeneration leads to a low yield of seedlings. It could be improved by prolonged pre-sowing treatment (cold stratification seeds) or early shading sowings, so that their effect on five seed lots and emergence growth seedlings were analysed. One lot came from USA; four Czech Republic. germination capacity rate analysed for without after 21-day 49-day stratification. was tested variants (shaded...
