تأثير استخدام تراكيز مختلفة من Soluamine و NaCl في النمو و مكونات الحاصل لصنفين من الحنطة الناعمة Triticum aestivum

Abstract EN

This experiment has been done in the green house in the Department of Biology / College of Education for Girls / University of Mosul, in order to study the effect of spraying plant with two different concentration of seaweed extract (Soluamine) 3, 6 mL / L at 3-4 leaflets stage and appearance Spikes stage under effect of NaCl in concentration of 3000 ppm, and to study their effects on some growth characteristics and yielded contents of two cultivars mild Wheat (Abu Ghraib 3, Ibaa 99).

These different concentrations of seaweed extract (Slouamine) lead to increase in both height of plant and the length of internodes.

The height of plant at concentration 6 mL / L reached 42.62 cm in comparison with control treatment in which the height of plant reached 30.68 cm and height ratio reached in length basal internode at concentration of 6 mL / L 55.67 % and the same thing in the length of apex internode, when the ratio of height reach at concentration of 6 mL / L 60.91 % in comparison with control treatment, and the concerning to characters of yielded content, there was an increase in the one hundred grain weight, when it reached at 6 mL / L concentration, 2.09 gm in comparison with control treatment 1.37 gm, in addition to increasing in tillers number, grain number in the spike and the same was found in the yield character, when the increasing ratio at concentration 6 mL / L 32.04 % in comparison with control treatment.

But by the treatment of NaCl, there was a negative effect on the plant height.

The plant height reached 33.92 cm in comparison with the plant that is not under NaCl effect which gave character range around 38.43cm , and the same thing in the length of internodes.

Also, the NaCl gave negative effect on the yielded content, when it decreases in grain number per spike, grain number in the plant, one hundred weight and the same thing in the yielded and in the cultivars effect, Ibaa 99cultivar appears to better than Abu-Ghraib cultivar in most of the characteristics, like the height, internodes length, grain number per spike and final yield.
