Abstract
The effects of exogenously supplied proline and hydroxyproline on potato (Solanum tuberosum) varieties L.T.8 and Desiree were studied using axillary bud cultures both in the presence and absence of 0.6% salt stress. In both varieties, the effects of exogenously supplied proline and hydroxyproline at 1.0 mM and 2.5 mMwere less severe than 0.6% salt alone. At the same time, the accumulation of proline, protein, carbohydrates, sodium, and potassium were similar. However, when both the salt and proline/hydroxyproline were supplied, proline and hydroxyproline provided some measure of protection against stress. It is believed that increased proline levels in L.T.8 and increased carbohydrates in Desiree due to the presence of exogenously supplied proline/hydroxyproline were responsible for the additional protection against salt stress in the axillary bud cultures of these varieties.....
