Acrylamide gel electrophoresis was used to separate anionic peroxidase isoenzymes in genotypes and genotrophs of flax. Activities and relative mobilities were measured directly from the separations on the gels.The effects of growth of one flax genotype in soil supplemented by either nitrogen, phosphorus and potassium (NPK) or nitrogen and potassium (NK) on subsequent generations of its progeny produced by complete selfing were studied. Both activity and relative mobility of anionic peroxidase isoenzymes displayed effects of fertilizer treatments applied in previous generations. NPK increased the relative mobility of all isoenzymes, while depressing the activity of at least three of them. Successive generations of growth in NPK produced approximately linear increases in relative mobility. Such environmentally induced heritable changes were detectable five generations later.Two other flax genotypes were crossed, and relative mobility and activity of anionic peroxidase isoenzymes were examined in both parents and F2 progeny. Between parents, there were differences in relative mobility for two of the four isoenzymes; their F2 hybrids showed intermediate mobility for these particular isoenzymes. There were no differences between reciprocal F2 hybrids for mobility or activity of any isoenzyme. The parents differed in activity in all four isoenzymes; the F2 hybrids displayed dominance towards the lower activity parent for each of the isoenzymes.Total anionic isoenzyme activity was highly correlated with gross peroxidase activity measured prior to electrophoretic separation.

The object of this study is supercritical carbon dioxide extraction of flax seed oil (Linum usitatissimum L.) at the pressures of 30, 40 and 50 MPa, temperatures of 47 and 52 ?C, extraction time of 4 h, special flows of solvent of 8.8 kg/(kg h), and particle size fractions of grinding material of 0.16-0.315, 0.315-0.80 and 0.80-2.00 mm. Supercritical fluid extraction (SFE) of the flax seed oil on the laboratory scale, with the special interest in the influence of the extraction pressure, temperature, extraction time, and grinding of ground material on the overall yield of the flax seed oil was investigated. Experimental results of the oil yields were compared with the data obtained by the mathematical model of Hong et al. [I.K. Hong, S.W. Rho, K.S. Lee, K.P. Yoo, Korean J. Chem. Eng. 7 (1990) 40], presented in the literature.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.

<p class="emsd-body"><span lang="EN-GB">Seeds of ten sesame cultivars (Karaj, Darab, Safiabad, Jiroft, Borazjan, Yellow-white, Felestin, Ultan, Isfahan and Abpakhsh) were sown into soil filled pots in 2008 and 2009. Pots were watered with six levels of salts (0.0038 (tap water as control), 4.89, 8.61, 10.5, 14.54, 17.74 ds.m<sup>-1</sup> NaCl) until full maturity. Plant height, root and shoot dry weight, yield and yield components, seed oil and protein contents of cultivars were measured. Increasing salinity caused significant reduction in plant height, root and shoot dry weight, yield and yield components, seed oil and protein contents of all cultivars. However, there were significant differences among the cultivars for measured traits for each salinity level. Based on seed oil yield data, Safiabad and Kraj at 0.0038ds.m<sup>-1</sup>, Safiabad and Ultan at 4.89ds.m<sup>-1</sup>, Ultan, Safiabad and Darab at 8.61 salinity levels were the superior cultivars. High variability in tolerance to salinity among the tested sesame cultivars suggests that selection of more salt tolerant cultivars for planting or breeding purposes is possible.</span></p><p class="emsd-body"><span lang="EN-GB">Highlights</span></p><p class="emsd-body"><span lang="EN-GB">Effects of contrasting salinity levels (0.0038 (tap water as control), 4.89, 8.61, 10.5, 14.54, 17.74 ds.m<sup>-1</sup>NaCl) on sesame cultivars were tested.

An experiment was conducted to study the effect of mulch (non-mulch and straw mulch) and different levels of nitrogen (0, 40, 80 and 120 kg ha-1) and potassium (0, 37.5, 75 and 112.5 kg ha-1) on the growth and yield of onion. Plants grown with straw mulch gave higher bulb yield (10.89 t ha-1) which showed 13.79% increase over non-mulch. Nitrogen increased the bulb yield significantly.The highest nitrogen level gave the highest bulb yield (12.13 t ha-1), which was 41.54% increase over control. Potassium increased bulb yield compared to control, but its different levels had identical results on yield. Nitrogen and mulch together produced significant variations. The Nitrogen at the highest level (120 kg ha-1) along with straw mulch gave the highest yield (13.31 t ha-1). Potassium together with mulch also exhibited significant variation on yield and yield components. Plants grown with the highest level of potassium (112.5 kg ha-1) along with straw mulch gave the highest bulb yield (11.58 t ha-1). Nitrogen and potassium as 120 kg N ha-1 × 75.0 kg K ha-1 gave the highest bulb yield (13.07 t ha-1). Nitrogen and potassium at their maximum levels with straw mulch gave the highest bulb yield (14.67 t ha-1).DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16747 Progress. Agric. 21(1 & 2): 39 - 46, 2010
