该试验目的是研究应用某些生理活性物质减弱γ射线对沙棘种子的辐射损伤,提高体细胞有益突变频率的可能性。经沙藏和未沙藏的沙棘种子用-800装置以照射量15千伦(临界剂量)和30千伦(亚致死剂量)、照射率498—592伦/分照射。照射前或照射后用下列活性物质处理:脱落酸1和2毫克/升,根皮苷25和50毫克/升,乙烯利50和100毫克/升,赤霉素25和50毫克/升,β-吲哚丁酸25和50毫克/升,6-
The purpose of this experiment was to investigate the possibility of using certain physiologically active substances to attenuate the radiation damage to the seeds of Hippophae rhamnoides seeds and increase the frequency of somatic beneficial mutation. Seabuckthorn seeds from the sand bank and the non-sand bank were irradiated with the -800 device at an irradiation dose of 15 thousand Lun (critical dose) and 30 thousand Lun (sublethal dose) with an irradiation rate of 498-592 Lun / min. Pre-irradiation or post-irradiation was performed with the following actives: abscisic acid 1 and 2 mg / l, phlorizin 25 and 50 mg / l, ethephon 50 and 100 mg / l, gibberellin 25 and 50 mg / - indole butyric acid 25 and 50 mg / l, 6-
