Pathogenicity of Pratylenchus brachyurus to rubber rootstocks
The pathogenicity of Pratylenchus brachyurusto rubber (Hevea brasiliensis) rootstocks was studied in two experiments: 1) opencross seedlings of 'Tjir 1' x 'Tjir 16' were inoculated with zero, 7,700 or 23,100 nematodes per plant; 2) illegitimate seedlings of 'GT 1', 'RRIM 527' and 'RRIM 600' were inoculated with zero or 12,800 nematodes per plant. After 195 (1st experiment) or 105 days after inoculation (2nd experiment), P. brachyurusdid not affect the relative growth percentage in terms of plant height in both experiments but significantly diminished the stem diameter percentage and increased the stomatal resistance of 'GT 1' , 'RRIM 527' and 'RRIM 600'.
