| Abstract | ||
| Suspension of two yeast types one of them isolated from soil and the other from yellow apple, Kodamaea ohmeri –AR1and Rhodotorula mucilaginosa –AR were used to determine their ability to enhance the growth of seelding wheat plant and improve it's growth characters. Results showed that plants inoculated with each type of the yeasts and planted on water agar medium caused significant root elongation with 9.1 and 8.6 cm respectively as compared to non-inoculated plants which was 6.6 cm. Seeds treated with yeast suspension and planted on peatmoss encouraged plant growth and improve growth characters of the plant and gave seedling hight and radical length equall to 22.7, 22.1 cm and 14.0, 12.9 cm as compared to un inoculated control plants with 19.0 and 8.2 cm respectively. Also increased the dry weight of shoot and root system by 0.030, 0.028, 0.035, 0.032 g/ plant-1 comparing with the un inoculated controls by 0.020 and 0.023 g / plant-1 for each of Rhodotorula mucilaginosa -AR and Kodamaea ohmeri –AR1respectively. Moreover increased the number of lateral roots and leaf area signitfcautly by 6.3, 6.1 and 6.3, 6.0 cm2 whereas for control plants it reached 4.6 and 4.8 cm2 respectively. Inoculated wheat seeldings with each of two type yeast suspension enhanced all test growth parameters high seeldings، length root، soft weight of vegetable total، soft weight of root total, dry weight of vegetable total, dry weight of root total, number of lateral root, paper area as well as chlorophyll content of the plants as compared with controls. ). | ||
