چکیده

The reproduction and pathology of Pratylenchus penetrans has been observed on five cultivars of lettuce (Lactuca sativa var. scarola) : Parella, Lattughino biondo Lollo, S. Anna, Regina dei Ghiacci and Aurelia a t different soil temperatures and light exposure periods in climate-controlled units. The maximum population increase occurred a t 21-220 and a t 14 hourlday in Parella and S. Anna varieties. Reproduction was reduced but notinhibitedat 14-150 and 12 hourlday, except in the Aurelia variety where reproduction ceased. None of the varieties tested were found to be resistant.

Pratylenchus penetrans Population Dynamics on Three Potato Cultivars.

Reproduction of Pratylenchus penetrans on the potato cultivars Hudson, Katahdin, and Superior was determined in greenhouse and field microplot experiments. Although all three cultivars were good hosts for P. penetrans, differences in reproductive rate were found. In one greenhouse experiment, Katahdin plants inoculated with 1,500 or 15,000 P. penetrans per pot had larger population densities at...

Ultrastructural Pathology of Cells Affected by Pratylenchus penetrans in Alfalfa Roots.

Cortical parenchyma cells penetrated and fed upon by Pratylenchus penetrans for 48 hours contained only cytoplasmic debris. Proximal cells had an increase in tannin deposits, degenerated mitochondria, increased numbers of ribosomes, and no internal membrane structure. Often the endodermis was collapsed and contained massive tannin deposits on the inner cell wall and cell lumen. Similar observat...

Twenty-four weeds commonly found in commercial potato fields in Quebec were evaluated for their host suitability to the root-lesion nematode, Pratylenchus penetrans, under greenhouse conditions. Brown mustard (Brassica juncea) and rye (Secale cereale) were included as susceptible controls and forage pearl millet hyb. CFPM 101 (Pennisetum glaucum) as a poor host.

Comparative Response of Alfalfa to Pratylenchus penetrans Populations.

Four populations of Pratylenchus penetrans did not differ (P > 0.05) in their virulence or reproductive capability on Lahontan alfalfa. There was a negative relationship (r = -0 .7 9 ) between plant survival and nematode inocula densities at 26 +/- 3 C in the greenhouse. All plants survived at an inoculum level (Pi) of 1 nematode/cm(3) soil, whereas survival rates were 50 to 55% at 20 nematodes...

Reproduction of Pratylenchus penetrans on Potato and Crops Grown in Rotation with Potato.

The relative suitability of potato and crops frequently grown in rotation with potato as hosts for Pratylenchus penetrans was evaluated. Suitability of rye, wheat, corn, oat, sorgho-sudangrass, and potato were compared in pot studies based on ratios of final population : initial population density and densities of nematodes in roots at harvest. Population densities increased more on potato, oat...
