Radiostimulating effect on tomatoes, pepper, and eggplants obtained after irradiation of the seeds with low doses of $sup 60$Co gamma rays (in Bulgarian)
The possibilities for exciting stimulation by presowing irradiation of dry tomato, pepper and eggplant seeds with low doses of /sup 60/Co gamma rays were studied. Dry seeds with equalized moisture content in advance were irradiated in a gamma unit of IGSR GUPE-4000 with a radiation power of 46-39 R/ min. The sowing was carried out immediately after irradiation and prickling out and planting in time in green house (during the autumnwinter period) and in the field (during the summer). The results obtained show that after presowing irradiation of dry tomato, pepper and eggplant seeds with low doses of gamma rays /sup 60/Co a stimulating effect is observed manifested in a higher index of early maturity in the first harvests after which gradually decreases and the irradiated varieties equalize in the yield with the controls. The rise of the index of early maturity is in the limits of about 15 to 30% on an average. The following most appropriate stimulating doses are established for greenhouse and field conditions in the region of Sofia: for eggplant, 2500 to 3000 R; for tomatoes, 1500 to 2000 R; for pepper, l200 to 1600 R.
