The empirical verification of TRANSP and TERGRA models was the main purpose of conducted researches. The models introduced in this paper describe the diurnal patterns of leaf temperature and transpiration when grass is exposed to increasing water deficit under field conditions. The difference simulation results of leaf water potential, leaf temperature and transpiration flux for low and high soil water potential rates and for different meteorological conditions show that these models need more research and measurements for a better identification of function aqd parameters especially for wet conditions, making these models more useful for irrigation scheduling, using the remote sensing techniques.

Pot experiments were designed to test the applicability of root electrical capacitance measurement for in situ monitoring of root water uptake activity by growing cucumber and bean cultivars in a growth chamber. Half of the plants were inoculated with Funneliformis mosseae arbuscular mycorrhizal fungi, while the other half served as non-infected controls. Root electrical capacitance and daily transpiration were monitored during the whole plant ontogeny. Phenology-dependent changes of daily transpiration (related to root water uptake) and root electrical capacitance proved to be similar as they showed upward trends from seedling emergence to the beginning of flowering stage, and thereafter decreased continuously during fruit setting. A few days after arbuscular mycorrhizal fungi-colonization, daily transpiration and root electrical capacitance of infected plants became significantly higher than those of non-infected counterparts, and the relative increment of the measured parameters was greater for the more highly mycorrhizal-dependent bean cultivar compared to that of cucumber. Arbuscular mycorrhizal fungi colonization caused 29 and 69% relative increment in shoot dry mass for cucumbers and beans, respectively. Mycorrhization resulted in 37% increase in root dry mass for beans, but no significant difference was observed for cucumbers. Results indicate the potential of root electrical capacitance measurements for monitoring the changes and differences of root water uptake rate.

Oilseed rape (Brassica napus L. ssp. oleifera Metzg) was the subject of the study in two forms: winter cv. ‘Muller’ (at the rosette stage – the first internode BBCH 30 – 31) and spring cv. ‘Feliks’ (at the yellow bud stage BBCH 59). The main gas-exchange parameters, net photosynthetic rate (PN), transpiration rate (E), stomatal conductance (gs), and intercellular CO2 concentration (Ci) were measured on leaves prior to the piercing and immediately after the short-term piercing. The effect of mechanical wounding revealed different progress of the gas exchange process for the two forms. Piecewise linear regression with the breakpoint estimation showed that the plants at the same age but at a different vegetal stage, manage mechanical leaf-piercing differently. The differences concerned the stomatal conductance and transpiration changes since for rosette leaves the process consisted of five intervals with a uniform direction, while for stem leaves - of five intervals with a fluctuating direction. These parameters got stabilized within a similar time (220 mins) for both forms. The process of net photosynthetic rate was altered by the plant stages. ‘Muller’ plants at the rosette stage demonstrated dependence of PN on time in log-linear progression: y (PN) = 8.01+ 2.73 log10 (x t2); 7 < t2 < 220; R2 = 0.96. For stem leaves of ‘Feliks’ plants the process of transpiration, in terms of directions, was convergent with the process of photosynthesis. Those two processes were synchronized from 1st to 114th min of the test (r = 0.85; p < 0.001) in plants at the rosette stage and from 26th to 148th min in stem leaves (r = 0.95; p < 0.001).

Alpine treeline is an important ecological boundary, marked by a change in site conditions and plant communities when crossing the forest limit, and tree growth at treeline is strongly constrained by the harsh environment. Finer resolution studies of tree radial variation on short temporal scales can be useful to explore the main physical variables that trigger the radial growth. From 19th Oct. 2008 to 25th Oct. 2009, we continuously monitored the stem radial variation of Picea meyeri Rebd. Et Wils trees using point dendrometers, at the treeline of Luya Mountains (altitude 2700 m a.s.l.), North China. Our results showed that there were two reverse daily variation patterns in the warm and cold seasons, which were related to the daily transpiration course and daily stem freeze-thaw cycles, respectively. Annual stem radial growth of Picea meyeri was divided into the four distinct periods: 1) spring stem rehydration, 2) summer stem rapid growth, 3) autumn stem dehydration contraction and 4) winter stem stagnation. The stem radial variation of Picea meyeri at the alpine treeline was closely dependent on climate conditions. Soil temperature was the most important factor affecting radial growth, which determined the initiation of radial growth and the cambial activity during the growing season.

Propagation conditions of bedding plants can eliminate or reduce the possibility of AMF inoculation of the root system during greenhouse production. Due to the ability of AMF to increase plant growth the effects of AMF and CO₂ enrichment on rooting and some physiological traits of geranium and osteospermum cuttings were investigated. AMF and CO₂ enrichment increased leaf number and fresh and dry weights of osteospermum shoots. Mycorrhization also significantly increased the length and fresh and dry weights of osteospermum roots formed in CO₂ enriched atmosphere but it did not affect root system developed in ambient atmosphere. AMF increased the length and fresh weight of geranium roots, irrespectively of CO₂ concentration, and dry weight of roots in CO₂ enriched atmosphere. Transpiration and stomatal conductance values were higher in inoculated osteospermum at higher CO₂ concentration. Mycorrhization and CO₂ enrichment increased photosynthetic activity of garden geranium leaves and this effect was connected with the increased ratio of variable to maximum chlorophyll fluorescence (Fv/Fm).

Copper is essential for the growth and development of plants. This micronutrient affects chlorophyll content, photosynthesis process and water relations in the plant. The objective of this study was to determine the effect of copper deficiency in soil on the rate of photosynthesis and transpiration, water use efficiency, leaf greenness and the yield of selected cultivars of perennial ryegrass (Lolium perenne L.) and orchard grass (Dactylis glomerata L.). During the growing season, the rate of photosynthesis and transpiration was measured using a LI-COR 6400 gas analyzer (Portable Photosynthesis System), and leaf greenness was estimated with a Minolta SPAD-502 chlorophyll meter. Water use efficiency (WUE) was calculated based on instantaneous values of photosynthesis and transpiration. Dry matter yield was determined by green matter drying to constant weight at 105oC. The results of the study indicate that copper deficiency significantly decreased the rate of photosynthesis and transpiration, chlorophyll concentration in leaves and the yield of all investigated cultivars. Perennial ryegrass cv. Maja was found to be most resistant to copper deficiency – it was characterized by a high rate of photosynthesis and transpiration, and by the highest chlorophyll content. The yield of cv. Maja attained under copper deficit conditions was comparable to that of other cultivars grown under control conditions.

The UE-imposed restrictions on the manufacture and use of plant protection chemicals necessitate screening for new substances that are more environmentally friendly. Biopreparations may constitute such a group; therefore, studies on their efficiency in the production of plant material are needed. This study evaluated the effects of two biostimulators on rhizogenesis and the gas exchange rate (respiration, photosynthesis, transpiration) of stem cuttings of dogwood (Cornus alba) as compared to conventional treatments with a rooting powder containing 2% auxin IBA and with aqueous IBA solution. Both biopreparations enhanced rhizogenesis; their efficiency varied depending on the cultivar, biostimulator applied, and the number of treatments. There was no relationship between rhizogenesis and physiological parameters tested. The experiments demonstrated that at least some biopreparations have potential in commercial production but their effectiveness may be different in different species and under different conditions.
