Determination of cluster size of Pratylenchus Penetrans phytonematode in a rose field

core number, plot size, Pratylenchus penetrans, Cluster size.
Abstract
A nursery field 21 m x 80 m was sampled sequentially for Pratylenchus penetrans by decreasing the plot sizes systematically. Plots sizes of 3.6 m x 8 m, 3.6 m x 3.6 m and 0.6 m x 0.6 m were sampled. Nematode counts were computed to obtain the respective sample mean and variance. The sample mean and variance were computed to obtain a and b values of the Taylor's power law. It is reported that the a and b-values of the Taylor's power law are influenced by plot size and number of cores per sample.
