Abstract

Improving the quality and flowering rate of cut flowers is important to meet consumer demand.
Therefore, it is necessary to develop methods to control flowering and senescence rates in ornamental plants.
This study investigated the effect of methyl jasmonate (MeJA) on the flowering of spray rose cultivars ‘Lovely Lydia’ and ‘Britney’. Shoot bases were immersed in aqueous solutions containing 0, 20, and 100 μM MeJA, in addition to 2% w/v sucrose, containing 0.02% w/v 8-hydroxyquinoline monohydrate.
Thereafter, we measured their flower opening, changes in flower and petal weight, and the vase life of the cut flower.
The flower opening of both cultivars was delayed following the treatment with 100 μM MeJA where flower wilting was suppressed in both cultivars, and vase life also became longer than in control.
In addition, the petal fresh weight was maintained high for 8 days after treatment.
However, there was no significant difference between the 20 μM MeJA treatment and control in both cultivars.
These data indicate that MeJA delayed petal growth and flower opening in both cultivars, resulting in longer vase life.
Although it is necessary to verify the effective treatment concentration, we conclude that MeJA shows high potential as a chemical agent for controlling flower opening in cut spray rose cultivars.
