The radiosensitivity of Albizia chinensis was determined by exposing its seeds to various gamma radiations doses. Air-dried seeds were subjected to numerous gamma irradiation doses using a 60Co gamma source (10 KR [kilorad], 20 KR, 40 KR, and 8.0 KR). The gamma irradiations were given in continuous and fractionated pattern. For analyzing the protagonistic and antagonistic e#ects of plant growth regulators with gamma radiations on xylogenesis development, GA3 and STIK were used for the experiment. The germination and vigor parameters were stimulated signi$cantly (p ≤ .05) by all fractionated doses. In contrast, the lower continuous doses (10 KRC [Continuous kilorad] and 20 KRC) increased the germination and vigor, while the higher irradiation inhibited the germination and vigor signi$cantly. The growth and biomass attributes of A. Chinensis seedlings were altered by the irradiations in a dose-dependent manner. In this study, we observed that the gamma irradiation and combination treatments were favorable in enhancing the xylogenesis mechanism than the pure gamma irradiations. The overall data of this study suggest that the morphogenesis, growth, anatomy, and unknown cellular events in A. chinensis are in%uenced by gamma irradiations. The current study using A. chinensis as a case study reports crucial cues for selecting a speci$c irradiation type or dose depending on the need to maintain or improve a speci$c germination, growth, or xylogenesis property
