Pistacia chinensis Bung seeds were irradiated to 100
200
400
600 and 800 Gy by 60Co γ-rays to study the biological effects.The results show that germination rate and survival rate of Pistacia chinensis seed decreased with increasing doses.The dose 200 Gy group has the highest variation rate and germination rate.The height of M1 seedling decreased with increasing doses.Compared with the control
dwarfing
plant type asymmetry
vein chlorosis
leaf curl
malformation and other phenotypic variation appeared with the irradiation groups of 100-400 kGy.Using RAPD
the M1 plants were investigated.Remarkable variations in the experimental plants were detected by RAPD PCR
but no variation was detected in the control plants.And the 200 kGy group has high frequencies of RAPD variation than the 100 kGy group.
