“…Flowers are extremely perishable; maintaining their physiological functions very actively even after harvest, and the beginning of their senescence very often depends on ethylene. 11 Delphinium flowers are very sensitive to ethylene; their sepals rapidly abscise upon exposure to it. 12 Vase life of cut flowers can be improved by delaying senescence using ethylene synthesis and receptor inhibitors.…”

Delphinium malabaricum (Huth) Munz. (Ranunculaceae), the only species of the genus Delphinium growing naturally in Western India, is endemic to Northern Western Ghats of Maharashtra. It produces beautiful and attractive spurred flowers of violet blue color with splendid green rosette foliage. Herein, we report our preliminary observations relating to seed germination, growth performance and post harvest performance of cut flowering stems of this plant. The annotations revealed that the seeds germinated throughout the year but the germination percentage was very low in March, April and May when there is high temperature. Plants grown from seeds collected from a wild habitat exhibited variation in their vigor, branching, leaves, flower color and number. Phenological studies showed that the vase life of Delphinium cut flowers is 5-7 days and are very sensitive to ethylene. A combination of sucrose and silver nitrate was determined as the best holding solution for cut Delphinium blooms, as it prevented flower abscission and slightly delayed flower senescence. Selection and breeding efforts are underway to further improve plant growth, flower quality and display life of cut flowering axis.

“…7 Cut flowers are very sensitive, because their degradation starts soon after detachment from parent plant and senescence induced by ethylene. 8 Gibbrellic acid (GA 3 ) is known to slow down leaf yellowing and control shedding of many famous cut flowers. 9 Gibbrellin possesses stimulatory effect on various parameters of plant like germination, breaking dormancy, delaying senescence and ethylene activity as well as quality flower initiation.…”

The pre-harvest treatment of gibbrellic acid (GA 3) as foliar spray was applied to chrysanthemum cultivars in order to investigate its impact on flower quality, persistency on plant and vase life. The Randomized Complete Block Design (RCBD) with two factors factorial arrangement was used with foliar application of GA 3 (0, 50, 100, 150mgL-1) sprayed on chrysanthemum cultivars (Rebbonet, Revert, Resomme and Magdalena) at button stage of flower buds. The foliar application of GA 3 significantly influenced most of the growth parameters and enhanced the quality of flowers in chrysanthemum cultivars. However, the chrysanthemum plants when treated with gibbrellic acid (GA 3) at the rate of 100mgL-1 resulted in maximum bud size (2.29cm), flower size (13.91cm), flower persistency on plant (51.14days), fresh flower weight (14.66g), dry flower weight (6.03g) and vase life (37.15days). The cultivar Rebbonet showed the highest bud size (2.28cm), flower size (12.20cm), number of days to flower persistency (47.00), fresh flower weight (12.45g), dry flower weight (5.08g), vase life (31.00days) and the least percent flower petal fading (9.69%). The foliar application of gibbrellic acid at the rate of 100 mg L-1 significantly influenced the growth and quality flower production of chrysanthemum cultivar Rebbonet. It was concluded that the cultivar Rebonnet could be sprayed with foliar application of gibbrellic acid (GA 3) at the rate of 100 mg L-1 to obtain quality flowers under the agro climatic condition of Peshawar,

“…La energía requerida, por ejemplo, para la biosíntesis de almidón o para la absorción de hierro es proporcionada por un compuesto intermediario rico en energía o coenzima, principalmente adenosin trifosfato (ATP) (Marschner, 1995). En este sentido, la senescencia de las flores cortadas está estrechamente relacionada con la reducción de la energía necesaria para las reacciones de síntesis (Figueroa et al, 2005).…”
