Interaction ofMeloidogyne haplaandFusarium oxysporumf. sp.medicaginison Alfalfa

Abstract

The incidence of fungal infection and vascular discoloration from a Moapa 69 also increased (P< 0.05) following sequential inoculations with single inoculation with Fusarium oxysporum f. sp. medicaginis was similar the two organisms and was greatest at 25 C. In Nevada Synthetic XX, the in Ranger alfalfa, susceptible to both Meloidogyne hapla and F. o. f. sp. incidence of fungal infection and root discoloration from combined medicaginis, and Nevada Synthetic XX alfalfa, resistant to M. hapla and inoculations (compared to the effects of a single inoculation with the susceptible to F. o. f. sp. medicaginis; less fungal infection and vascular fungus) increased (P< 0.05) only at 30 C, where resistance to M. hapla is discoloration occurred in Moapa 69 alfalfa, susceptible to M. hapla and lost. Combined inoculations suppressed the incidence of root-knot galling resistant to F. o. f. sp. medicaginis. Fungal infection and root discoloration (P < 0.05) and nematode reproduction (P < 0.05) on both Ranger and increased (P< 0.05) and plant growth decreased (P< 0.01) in Ranger and Moapa 69, but not on Nevada Synthetic XX. Single inoculations with M. Moapa 69 at 20-30 C when inoculation with M. hapla preceded inoculation hapla reduced (P< 0.05) the growth of Ranger and Moapa 69 at 25 and 30 with F. o. f. sp. medicaginis by 28 days. Plant mortality in Ranger and C and Nevada Synthetic XX at 30 C.

Interaction between Meloidogyne incognita and Rhizoctonia solani on green beans

“…This finding agrees with previous similar reports on the adverse effects of several soil-borne fungi on the reproduction of Meloidogyne spp. on several crops (Mokbel et al, 2007; Al-Hazmi, 1985; France and Abawi, 1994; Griffin and Thyr, 1988; Sharma and Gill, 1979; Powell, 1971; Mousa and Hague, 1988). The great damage on roots caused by R. solani may have affected the nematode feeding process within the root tissues and, subsequently, adversely affected the nematode reproduction.…”

“…Mặt khác, nấm F. oxysporum được chứng minh là gây biến đổi sinh lý của cây ký chủ giúp có lợi cho nó (Knogge, 1996) và những biến đổi này làm suy giảm khả năng tạo nốt sần, khả năng sinh sản của tuyến trùng và khả năng nở của trứng (Ribeiro et al, 2012). Sự suy giảm sinh sản tuyến trùng đó cũng được tìm thấy trong hệ thống bệnh M. hapla -Alfalfa -F. oxysporum (Griffin & Thyr, 1988).…”

Literatuurstudie naar interacties plantparasitaire aaltjes met plantpathogene bodemschimmels : beschrijving van interacties en mechanismen en hun betekenis voor de akkerbouw en bollenteelt

“…Auteurs van verschillende artikelen merken op dat abiotische stressfactoren, waarbij in het bijzonder stress door hitte (Griffin & Thyr, 1988), droogte en kou worden genoemd, het (gedeeltelijke) verlies van resistentie en tolerantie in de hand werken. Dit komt waarschijnlijk omdat de plant deels op dezelfde manier reageert op signalen van biotische als abiotische stress.…”
