خلفية البحث و هدفه: يقوم النبات باصطناع المواد الأولية من خلال عمليات الاستقلاب الأولي، و ذلك من أجل الاستمرار في العمليات الحياتية الضرورية.
أما في الحالة التي يتعرض فيها النبات إلى تثبيط النمو نتيجة للظروف البيئية الشديدة مثل الملوحة فإن نبات الديجيتال الأرجواني المستخدم في هذه التجربة يغير من قدراته الحيوية مثل الاصطناع الحيوي من أجل تشكيل مواد
أخرى ضرورية تدخل في عمليات الاستقلاب الثانوي، و من ثَم تؤثر في اصطناع الغليكوزيدات المقوية للقلب Cardenolides و منها الديجوكسين.
Background & Objective: The plant creates raw materials through primal metabolism in order to
maintain crucial lively operations.
While in the case that the plant is subjected to inhibition of growth as a result to environmental
circumstances characterized by a high level of salinity, the Digitalis Purpurea used in this experiment
changes its biological potential like bio-creation to form other necessary materials that take part in
secondary metabolism operations, and hence affect the creation of glycosides that strengthen the heart,
which Digoxin is one of.

The effect of salinity and the treatment with fungicide on seed germination of Cupressus
sempervirens L. was investigated.
Five concentrations of salinity (0, 0.5, 1, 5 and 10%) were used. One part of the seeds was
treated with fungicides (Benomyl
