Reaction of Trifolium repens Cultivars and Germplasms to Meloidogyne incognita.
Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest perce...
متن کاملExpression of Resistance to Meloidogyne incognita in Kenaf Cultivars (Hibiscus cannibinus) under Field Conditions
Field studies were conducted in 2003 and 2004 to investigate the reaction of 10 varieties of kenaf to natural infestation of Meloidogyne incognita. Ten weeks after planting, ten randomly selected plants per variety were assessed for root galling. Plants were carefully uprooted soil adhering to roots was washed off under a gentle stream of tap water and roots then were observed using a stereo mi...
متن کاملTrichoderma harzianum reduces population of Meloidogyne incognita in cucumber plants under greenhouse conditions
Trichoderma harzianum strain ESALQ-1306 was assessed for its potential biological control against Meloidogyne incognita race 4 under in vitro and greenhouse conditions. In vitro, we noticed 64% of conidial attachment on eggs and second-stage juvenile immobilized by the fungus. In greenhouse, cucumber plants were treated with different concentrations of conidial suspensions before and after inoc...
متن کاملReaction of Ten Cultivars of Watermelon (Citrullus lanatus) to a Puerto Rican population of Meloidogyne incognita.
Ten cultivars of watermelon were evaluated for their response to a Puerto Rican population of Meloidogyne incognita under greenhouse conditions in a 2-year study (1989 and 1990). Ten-day-old seedlings were planted in steam-sterilized soil in 15-cm-d plastic pots. The nematode inoculum consisted of 10,000 eggs and (or) second-stage juveniles (J2)/plant. The cultivars were Sugar Baby, Charleston ...
متن کاملa study on the reaction of six tomato cultivars against root-knot nematode meloidogyne javanica under greenhouse conditions
the reaction of four field tomato cultivars (super strain b, super chief, mobil, and royal) along with two greenhouse cultivars (polaris and es 1002 f1) was evaluated agianst m. javanica under greenhouse conditions. the soil around tomato seedlings (bearing 5-6 leaves) was inoculated with two levels of the nematode inoculum i.e. 1000 and 2000 eggs as well as second stage juveniles per every kg ...
