<p class="4Body">Total Dray Matter (TDM), Photosynthetically Active Radiation Intercepted (PARabs), Water Consumption (WC), Water use- (WUE), Radiation use efficiency (RUE) and the Relation between Radiation Interception and Water Consumption for Durum Wheat were investigate under different irrigation amount (D<sub>1</sub>= 100 % ETc; D<sub>2</sub>= 70 % ETc; D<sub>3</sub>= 40 % ETc and D<sub>4</sub>= pluvial) and during three growing seasons (2005-2006, 2006-2007 and 2007-2008). Results showed that, the cumulative PARabs decreased with deficit irrigation. In fact, D<sub>1</sub> treatment recorded the highest cumulative PAR abs and the lowest marked under D<sub>4</sub> treatment. Similarly, TDM and RUE were decreased with deficit irrigation. The highest RUE observed under the D<sub>1</sub> (from 1.32 to 1.43 g MJ<sup>-1</sup>) and the lowest under D<sub>4</sub> (from 1.17 to 1.29 g MJ<sup>-1</sup>). However WUE increased with deficit irrigation. The highest WUE were obtained under the D<sub>4</sub> (from 3 to 4 kg m<sup>-3</sup>) and the lowest were observed under D<sub>1</sub> (from 2.8 to 3.1 kg m<sup>-3</sup>). Significant linear relationship was found between cumulative PAR abs and cumulative water consumption with a high correlation coefficient (R<sup>2</sup>) only under the two treatments D<sub>1</sub> and D<sub>2</sub>.</p>

Investigations were carried out in 2007-2009 on the plots of the Felin Experimental Station belonging to the University of Life Science in Lublin. The studies comprised two cultivation lines of durum wheat (<i>Triticum durum</i> L.): STH 716 and STH 717, as well as the 'Tonacja' cultivar of common wheat (<i>T. aestivum</i> ssp. <i>vulgare</i> L.). Two levels of chemical protection were applied in the cultivation: minimal and complex protection. Infection of wheat roots and stem bases was recorded in each growing season at hard dough stage (87 in Tottman's scale, 1987). After three years of study, the mean disease indexes for the analyzed wheat genotypes in the experimental treatment with minimal protection were 31.13, 30.43 and 38.83 for, respectively, the 'Tonacja' cultivar and the cultivation lines of <i>T. durum</i> STH 716 and STH 717. In the experimental combination with complex protection, after three years of study the disease indexes ranged from 25.26 (<i>T. durum</i> STH 716) to 30.83 (<i>T. durum</i> STH 717). The results of mycological analysis of diseased plants showed that <i>Fusarium</i> spp., especially <i>F. culmorum</i>, <i>F. avenaceum</i> as well as <i>Bipolaris sorokiniana</i> and <i>Rhizoctonia solani</i>, caused root rot and necrosis of wheat stem bases. The analyzed chemical protection levels did not significantly influence grain yield of the investigated genotypes of <i>T. aestivum</i> and <i>T. durum</i>.

Variations in seed pigment concentrations of Triticum durum Desf. cv. Hercules were studied during two growing seasons. In the second season, the effects on seed pigment of spraying durum wheat with CPTA (chlorophenylthiotriethylamine) at 3.9 kg/ha, 1 and 2 wk after flowering were also studied. Normal pigment synthesis showed one period of synthesis for chlorophyll, but two for carotenoids. One complement of carotenoids seems to be associated with the chloroplast, while the other is probably located in the endosperm. CPTA appeared to affect the size and duration of chlorophyll and α + β carotene pools. Lutein concentrations at 33 days after flowering were at the same level in sprayed and non-sprayed samples. Since mature seeds showed pigment increases of up to 20% after spraying with CPTA, a late synthesis of lutein is indicated.
