| Abstract | ||||
| Aiming to study the marjoram (Majotana hottensis L) potential to survive under salinity condition and to find out the effect of some bio-fertilizers on this potential, two experiments were conducted in Baramoon Experimental Station, Dalcahlia Govemorate, Egypt, during two successive seasons of 2003-2004 and 2004-2005. The present investigation were planed to test (4) levels of saline water as well as foliar nutrition by some biocompounds i.e., Askobein, Novitrein, Carein and Anciabein mixtures effects and their interactions on plant growth, essential oil, quantity and quality. Marjoram seedlings were grown in plastic bags. Plants irrigated with saline water displayed deleterious effects on all growth characters, and these effects were proportional to salinity concentrations. Marjoram plants showed a quite tolerance to salinity at 2000 ppm, whereas the excess concentration (4000 and 6000 ppm) caused a severe damage to the irrigated plants, a remarked reduction in survival percentage and significantly reductions of leaves essential oil percentage. Oil analysis by gas liquid chromatography showed that saline water slightly decreased percentages of main components at levels of 2000 and 4000 ppm, whereas 6000 ppm caused vanishing of some constituents and caused severe harmful to oil principals. All bio-compound I. e., Novitrein, CAtrein, Askobein or Anciabein, slightly caused significant increments on the studied plant growth characters and displayed the best estimates in the two seasons. Applicabon of these compounds raised the plant potential to tolerate salinity and simultaneous increased the survival percentage. In addition utilizing these compounds slightly increased oil active principals and could be overcome the harmful effect of saline irrigation water. | ||||
