Effect of aminooxyacetic acid (AOA) on ACS and ACO genes expression and the vase life of alstroemeria cut flower

Abstract

Aging in the limbs is divided into two categories: ethylene-sensitive limbs, and ethyleneinsensitive limbs. Extracellular synthesis of ethylene in the first group is carried out through a specific biochemical pathway that results from flower development and pollination. The present study aims to explore the effects of aminooxyacetic acid (AOA) on the expression of ethylene biosynthesis pathway genes (1-aminocyclopropane-1carboxylate synthase (ACS) and 1-aminocyclopropane-1-carboxylate oxidase (ACO)) and the vase life of the Alstroemeria cut flowers 'Mayfair' and 'Frosty' varieties. Also, the effect of AOA on at the rates of 0, 50, 100 and 150 mg/l was studied on the morphological and physiological traits. The comparison of the vase life of Mayfair and Frosty showed that Frosty had a longer vase life than Mayfair. Frosty exhibited lower levels of cell degradation, higher relative water content, more chlorophyll content, more 862
