To be exposed to UVC, plants were grown on soil and at 14 days post germination were irradiated with 7,000 ergs UVC. Control plants were grown under normal conditions. To be exposed to salt stress, plants were germinated and grown on MS medium supplemented with 25 mM NaCl. Control plants were grown on normal MS medium. At the age of three weeks plants were moved to soil. Control and stressed plants were selfed giving rise to PC and PS plants. Stressed plants were also used to cross-pollinate control plants in reciprocal manner giving rise to PS_m and PS_p plants. Five plants for each reciprocal cross were used. HRF was analyzed in the population of 50–100 plants at three weeks post germination. Asterisks show the difference in HRF as compared to PC plants (one—p < 0.05; two—p < 0.01).
