Abstract
Physiological studies on Ocimum basilicuum. L
and Ambrosia maritima, L. plants
Two pot experiments were conducted at the Horticulture Research Station, El-Tahrir in two successive seasons of 1998 and 1999, aiming to study the response of two aromatic plants namely. Ocimum basilicum, L. and Ambrosia maritima, L. to salinity of irrigation water as nine (9) treatments of saline irrigation water plus the control treatment in which the irrigation water was not salinized with any salt were used. Salts used were NaCl, CaCh and their mixture at I : I by weight as the concentrations of each salt were 1500, 3000 and 4500 ppm.
The following results were obtained for each chosen plant:
1- The different levels of NaCl, CaCl, and their mixture in the irrigation water decreased the plant height, number of shoots, fresh and dry weight of herb, root length and fresh and dry weight of roots. The highest level of salinity gave the lowest values for all parameters.
2- The different salinity levels in the irrigation water decreased oil percentage and oil yield/ plant in the herb.
3- AII salinity treatments decreased plant pigments content (Chlorophyll a
and b) in the leaves.
4-The different levels of NaCl, CaCl and their mixture in irrigation water decreased nitrogen, phosphorus, potassium and magnesium, percentages in the leaves of each plant.
5-For sodium and calcium the different levels ofNaCl, CaCh and their mixture in irrigation water increased their percentages in the leaves of each plant.
