Melatonin enhances nitric oxide, salicylic acid, and lignin accumulation to reduce neck bending and extend vase life of gerbera cut flowers

open access: yesBMC Plant Biology
Melatonin (MT) is a versatile signaling molecule involved in plant growth regulation and stress tolerance. This study examined the effects of MT at five concentrations (50, 100, 200, 300, and 400 µM) on neck bending (NB) and vase life of Gerbera ...

Calcium Chloride as a Regulator of Floral Stem Bending in Cut-Flower Gerbera (Gerbera jamesonii L.)

open access: yesRevista de la Facultad de Ciencias Agrarias
Gerbera is an ornamental plant with vibrant and striking colours. However, postharvest stem bending reduces commercial quality and limits vase life by impairing water uptake. Calcium plays a key role in regulating and strengthening the stem structure,
