Karyotype Analysis of Pisum arvense L. Collected from Tokat Native Vegetation

Abstract

This research was conducted to determine karyotype analysis of Pisum arvense L. occurred in native vegetation of Tokat region. After the seeds were germinated, they were stained by feulgen and karyotype analysis was carried out with obtained cells by using the squash method. The results of the cytological studies that the chromosome numbers of Pisum arvense L. were 2n= 14. Four chromosomes of the Pisum arvense L. were submedian and ten chromosomes were median. In addition, the chromosome length, the arm index and the relative chromosome length in Pisum arvense L. were 4. 59-5.93 p, 0.56-0.91 and 6.38-8.24, respectively.
