| description | Resistance genes in response to root-knot nematode (Meloidogyne javanica) infection suppress
one or more of several critical steps in nematode parasitism and their reproduction
rate. The reaction of seven commercial tomato genotypes to M. javanica infection was investigated
under greenhouse conditions. Current results classified these genotypes as: three
resistant (Jampakt, Malika and Nema Guard), one moderately resistant (Fayrouz), and
three susceptible (Castle Rock, Super Marmande and Super Strain B). Except Nema Guard,
nematode infection significantly reduced plant height, fresh and dry weights of shoots of
the other tomato genotypes. Leaf area was significantly reduced for all examined tomato
genotypes except Malika and Nema Guard. Total chlorophyll was reduced in all tested
tomato genotypes except Jampakt. Infection parameters of M. javanica and their population
were significantly reduced on all nematode-resistant tomato genotypes compared
to the susceptible genotypes. Also, the maturation rate of M. javanica was suppressed in
the resistant genotypes compared to the susceptible genotypes. These results were confirmed
by histological study that illustrated a delay in nematode development and their
maturation. Total phenolic content significantly increased in nematode infected roots of
both resistant and susceptible genotypes except Malika. Among non-infected roots, Malika
showed the highest level of total phenols while after M. javanica infection, Nema Guard
revealed the highest level of total phenols. Among infected roots, the highest level of total
phenols was recorded in Castle Rock. These results suggested that using nematode-resistant
tomato genotypes could provide an efficient and nonpolluting method to control root-knot
nematodes. |
