- Abstract
The aim of this research was to determine the phytotoxic effect of chemotherapeutic products over meristematic explants from two potato Romanian varieties: Marvis and Castrum. Potato meristems were cultured on nutritive medium containing four virocid chemicals: ribavirin, 5-bromouracil, 2-thiouracil and acyclovir in three concentrations (0, 15, 30 mg/l). Meristems development varied for tested antiviral agents and was decreased with increasing in concentration of antiviral products (from 0 to 30 mg/l). Antiviral products with high concentration (30 mg/l) had a negative effect on regeneration. By using 5-bromouracil the highest regeneration rate was observed (for 15 mg/l and 30 mg/l), compared to the other antiviral substances, with the same concentrations. Another chemotherapeutic 2-thiouracil exhibited phytotoxicity and reduced meristems regeneration. The lowest percentage of regeneration was registered by using of 15 mg/l 2-thiouracil compared to the other antivirals, at the same concentration. Percent of meristems regeneration was very low for ribavirin and 2-thiouracil at 30 mg/l concentrations (40%). For Castrum variety 5-bromouracil is distinguished by obtaining a very significant positive difference (19.17% regenerated meristems), but the virocid 2-thiouracil is at the opposite pole, inhibiting the regeneration of explants, with a very significant negative difference (-14.17% developed explants).
