The present study was done at Antoniades Research Branch, Ornamental Plants Research and Landscape Gardening Res.

Dept.

, Hort.

Res.

inst.

, ARC, Alexandria, Egypt, during the two successive seasons of 2019 and 2020.

The aim of this work was to evaluate the ability to use Nigella sativa, Rosmarinus officinalis and Citrus lemon essential oils (EOs) at 0.0, 50, 100, 200 mg/l as holding solution on reducing bacterial decay and prolonging the vase life of solidago cut spike.

The highest significant increase in vase life was obtained after application of Nigella EO at 200 mg/l which was 15.78days in the first and 16.85 in the second season respectively as the compared to rosemary, lemon oils and control treatments.

While the vase life of control treatment was 6.98 and7.00 days in both seasons respectively.

Also, this treatment recorded the highest significant increase in final water uptake, shoot fresh weight/shoot dry weight ratio and chlorophyll a & b content.

Moreover, this treatment caused decreased in the loss of flower fresh weight and reduced the number of bacterial colonies in vase solution.
