Effecf of Mint Essence And Ultraviolet On Thyme and hock Seed Germination

In order to Investigate the allelopathic effects of menthol and UV damage as a parameter of the effects of ozone on thyme and hock seed germination. In this research in two separate trials، the effect of menthol (25% -50% -75% and 100%) and 3 ultraviolet spectrum A (nm 400 – 320) and B (nm 320 - 290) and C (nm290-200) and control based on randomized complete block design in three replications in the laboratory of Mylajrd Payam Noor University were tested. According to the results of the phenology of plant growth and seed germination in four levels and five levels of radiation considered menthol، The results showed that the highest percentage of dewatering is in seeds control varieties treatment by 81% in thyme and 74% in hock، but there are significant difference between other treatments. Based on germination percentage، highest has been in control plants thyme with 81% and control hock with the 73%، respectively، with increasing concentration of menthol in hydroponic culture from 25% to 100%، germination has decline substantially from 77% to 51% in thyme and 71% to 39% in the hock. In addition، between the control treatment of seeds with 25% menthol treatment There was no significant difference between treatments، but treatment with 50%، 75% and 100% was seen difference significant at 1% level according to Duncan test. In examining the results of treatment by ultraviolet rays was a significant difference. control treatment has the highest performance with the germination of 81% in thyme and 70% in the hock and results show that we have treatment UVA treatment with the treatment of other ultraviolet radiation significant difference at 1% Duncan test.
