EFFECT OF SOME PHYSIOLOGICAL AND BIOLOGICAL TREATMENTS ON THE GROWTH, FLOWERING, CHEMICAL AND ANATOMICAL COMPOSITION OF ANTIRRHINUM MAJUS L. PLANT
Antirrhinum majus, vegetative growth, flowering, chemical constituents, anatomical structure.
This work was to study the effect of diatomite at the rate of (10,20 and 30%), putrescine at the rate of (100,200 and 300ppm)and alpha tocopherol at the rate of (400,800 and 1200 ppm)in addition to control (distilled water) on vegetative growth, flowering ,chemical constituents and anatomical structure of Antirrhinum majus L.plant during (2011/2012 and 2012/2013). Using diatomite at the rate of 30% gave the highest increase in all characters of vegetative growth, flowering, chlorophylls content, anthocyanin content, total carbohydrates content, minerals content, stem diameter, the xylem thickness, epidermis, cortex of stem anatomical structure and the leaf thickness of palisade, spongy tissue, xylem, phloem, development for floral bud which was earlier than other concentrations 10 and 20%. Application of putrescine at the concentrations of 200 ppm gave the best results in all characters of vegetative growth, flowering, chlorophylls content, anthocyanin content, total carbohydrates content, minerals content, stem anatomical structure, leaf anatomical structure a decrease in number of days for flowering than control plants in both season.Treated plants with 800 ppm alpha tocopherol gave the highest significant increase in all vegetative, flower characters, photosynthetic pigments after 60 days from transplanting, anthocyanin and total carbohydrates contents, minerals contents, increased stem diameter, xylem, phloem thickness and decreased pith thickness in stem anatomical structure, leaf anatomical structure gave a lowest day to first flower appearance in both seasons than other treatments (400 and 1200ppm).
