PHYSIOLOGICAL AND BIOCHEMICAL INFLUENCES OF SOME SAFETY TREATMENTS ON ONION PLANTS
Horticulture Department, Faculty of Agriculture, University of Menoufia, Shebin El-Kom, Egypt.
Abstract
Effects of five different non-traditional treatments i.e. magnetic water, humic acid, seaweeds extracts, mycorrhzyia fungi and organic fertilizers in addition to the traditional mineral recommended fertilizer were determined in aspect to different growth characteristics within onion plants grown in two subsequent seasons under open field conditions in station of faculty of agricultural at minufiya university. The correlation between of the tested treatments and the accumulation of different biochemical active compounds within treated onion such as ploy phenols, and peroxidases substrates were investigated through using HPLC apparatus. The results showed that the highest recorded growth and vegetative criteria were observed on plants treated with mycorrhyza fungi followed by magnetized water. On contrary, the lowest growth and vegetative values were recorded by organic fertilizers and traditional recommend fertilizers. Biochemical analysis using HPLC revealed that cinamic acid substrate was detected only within treated plants by sea weeds extracts, humic acid and recommended mineral fertilizers. The highest accumulation of peroxidase enzyme was observed with mycorrhyza and sea weeds treatments. The results showed also that Mycorrhyza fungi, sea weeds extracts, organic fertilizers in addition to recommend mono fertilizers increased the accumulation of poly phenols substrates more than all other tested treatments.
