The Effect of Temperature and the Extract of (Ascophyllum Nodosum) on the Chemical Content of Thyme Plant

Abstract

I have studied in this research the effect of temperature and the extract of (Ascophyllum Nodosum) on the chemical content of thyme plant, where I have planted thyme seeds on 25/November/2021 in plastic pots, with 10 seeds per pot using seven treatments included a regular temperature, low temperature (5cº) and high temperature (50 cº) and two concentrations of (Ascophyllum Nodosum) extract, first one 25% and the second 50% and in temperature of (5cº+25%) and (5cº +50%) and in temperature of(50 cº+25%) and (50 cº+50%) by 5 repetitions for each treatment,. A mixed soil was used for the cultivation and the highly advanced dutch origin peat moss fertilizer type (van egmond) was used and as was mentioned in the brochure it contains high volume of the necessary elements besides the potential hydrogen (PH) level in it ranges between 5-6.5, and the electrical conductivity (E.C.) ranges between (0.8-1.5) and it’s good for the continuity of plant’s growth for a duration of (4-6) weeks and after the plants reached the adult phase they were treated by spraying them with (Ascophyllum Nodosum) solution with the required concentrations and after three weeks the enzymatic response was measured ( catalase and Peroxidase) and the hormonal response ( the likes of Gibberellins and Auxins) of the plant. And the results were statistically analyzed by using (SPSS) Statistical Package for the Social Sciences software at the Statistical significance level of 0.05, and the results suggested that the treatment of (50 cº+50%) was the best while the treatment of 5 cº with both concentrations was less responsive among the other treatments.
