Abstract
:
Glomus clarum symbiosis of watermelon plants gave positive results in their tested growth paramet rs of ShOOI and root systems lengths and dry weights, as well as, leaf pigmentation of chlorophyll a.b and carotenoids and the elements contents of , P, Ca. Mg, K and a, compared to non-mycorrhizal plants. The mycorrhizal infection and spore population were markedly influenced by the pesticide level. Half of the recommended concentration of the nematocide (Furadan- ~ 0) was responsible for about 39 and 590/0 increase of mycorrhizal colonization and spore production. While the 10\ er fungicide level increased mycorrhizal infection by 6%. The recommended levels and the duplicates of both pesticides were conducive to mycorrhizal activities, At the latter levels, nematocide was obviously more drastic to Glomus clarum than the fungicide. Growth of watermelon r sponded di fferently to the applied pesticid level and mycorrhizal inocula' on. At half of'the recomm nded levels. mycorrhizal plants ha e higher alues of growth parameters comparing to pesticides free plants. while a.clorum free plants show lower values. Increased pesticides levels were deleterious to watermelon growth parameters. However. plant pigments appeared 10 les susceptible 10 pesticide stress. The nematocide Furadan-10 was more drastlc to the gro ih parameters of watermelon, either mycorrhizal or non-mycorrhizal colonized. than do the fungi id (Rizolex-T-60wg) instead of the applied nematocide te els were haJfthat of the fungicide
