Influence of Root-Dipping Tomato Roots within Water Extracts of Three Composite Grinded Seeds under the Infection of Meloidogyne incognita

Abstract

A trial test was set to assess the impact of root-dipping of tomato cv. Alisa plants separately for 15 or 30 minutes within aqueous grinded seeds extracts of three compositae seeds extracts i.e. chicory, artemesia and chrysanthemums below the anxiety of M. incognita disease in the greenhouse circumstances (29±2°C). Every one of the experienced materials mend the increments proportion enlarge values of plant vegetation metrics of tomato plants and decrease nematode gauges too. Evidently, tomato plants growth metrics were positively improved when the time of root dipping raised from 15 to 30 minutes. Plant getting artemesia ranked first with the maximum rates values that was between 68.57 and 82.85% or 28.12 and 46.87% or 55.6 and 77.8% for plant height, sum plant fresh and shoot dry weights for root dipping treatment for 15 and 30 minutes, that talented the highest percentage of reduction in final nematode population, number of galls and egg-masses, with values of 66.7, 68.0; 64.7, 61.7; 78.12 and 81.25%respectively. On the other hand, chicory grinded seeds extract recorded the slighter values for similar nematode metrics which were almost on par either at 15 or 30 minutes, these values were averaged 28.1, 42.3; 44.1, 55.8 ; 78.12, 81.25% for reduction percentage of total nematode numbers, galls and eggmasses numbers, in that order. It was plain that N,PandK concs, total chlorophyll; phenol contents were noticeably increased by infection of nematode. Every experienced components at 30 minutes of root-dipping in such tested aqueous grinded seeds extracts recorded better values of N,PandK, total phenol and chlorophyll contents than those results at 15 minutes of root dipping. The resulted values ranged between 4.5 to 33.0% or 5.5 to 58.9% or 6.9 to 31.4 or 6.05 to 14.21 or 0.55 to 5.53 for N,P and K concentrations and total chlorophyll and phenol contents of chicory at 15 min (lowest values) to artemesia at 30 (highest values) min of root-dipping within such aqueous tested extracts, respectively.
