“…Also, SA inhibited the ethylene biosynthesis and delayed senescence progress in plant tissues (9). These results are in agreement with those of (10,11) who found that adding SA, MA and GLU in vase water increased chlorophyll content cut flowers. similarity, Canakci (12) reported that treatment with salicylic acid significantly extends the vase life with increases chlorophyll content.…”

Effect of salicylic acid (SA) combined with citric acid (CA) on gerbera (Gerbera jamesonii) cut flowers was studied. The study was conducted in a factorial arrangement, carried out in a complete randomized design. The factors were SA (0.5,1.5 and 3 mM) and CA (1.5 and 3 mM). The effects of treatments on the total chlorophyll content, anthocyanin leakage and malondialdehyde content of cut flowers of gerbera were investigated. The results showed that the vase solution containing 1.5 mM SA significantly increased vase life compared to the control. In addition, the malondialdehyde accumulation reduced in the same solution while membrane stability was improved. Results suggest that SA increases vase life by affecting many of the age-related changes associated with Gerbera petal senescence.

“…Aminooxyacetic acid extended vase life, which correlated with a 40% decrease in endogenous proline content of senescing petals compared to untreated flowers ( Yakimova et al, 1997 ). Also, application of the plant hormone salicylic acid (SA) to lisianthus flowers ( Eustoma grandiflorum Mariachi ) doubled the vase life, which correlated with a 75% reduction in proline content ( Kazemi et al, 2011 ). It is possible that the lower proline content observed with SA treatment is due to increased PRODH activity in the petals.…”

The amino acid proline has a unique biological role in stress adaptation. Proline metabolism is manipulated under stress by multiple and complex regulatory pathways and can profoundly influence cell death and survival in microorganisms, plants, and animals. Though the effects of proline are mediated by diverse signaling pathways, a common theme appears to be the generation of reactive oxygen species (ROS) due to proline oxidation being coupled to the respiratory electron transport chain. Considerable research has been devoted to understand how plants exploit proline metabolism in response to abiotic and biotic stress. Here, we review potential mechanisms by which proline metabolism influences plant senescence, namely in the petal and leaf. Recent studies of petal senescence suggest proline content is manipulated to meet energy demands of senescing cells. In the flower and leaf, proline metabolism may influence ROS signaling pathways that delay senescence progression. Future studies focusing on the mechanisms by which proline metabolic shifts occur during senescence may lead to novel methods to rescue crops under stress and to preserve post-harvest agricultural products.

“…On the other hand, the observed higher vase life in the lower planting density might be due to the adequacy of the nutrients which ensured the presence of enough stored food in the harvested stems (Ghaffoor et al, 2000;Da Silva, 2003;Kazemi et al, 2011).…”

. Conversely, flowers' vase life significantly (P<0.01) decreased when planted densely. In addition, the fresh weight of the marketable stems significantly (P<0.01) decreased as planting density increased. Among the cultivars, 'Yellow Sun Bird' was found to be more productive in terms of marketable stems followed by 'Giant Blue Bird' and 'Amazon'. In terms of stem length, 'Yellow Sun Bird' was found to be higher but was not statistically different from 'Giant Blue Bird'. With regards to vase life quality, the best result was obtained from 'Amazon Bird' cultivar. Overall, the study reveals that planting density and varietal differences had valid effects on the yield and quality of Statice. Cultivars 'Giant Blue Bird' and 'Yellow Sun Bird' had better performance in many of the parameters than the 'Amazon Bird' cultivar. The highest planting density (10 plants per m 2 ) demonstrated a positive influence on most of the evaluated parameters and therefore can be recommended for use by commercial growers in Ethiopia. However, further investigation is imperative on issues pertaining to the determination of nutrient supply for regulating the fresh weight of the product and other economic related topics.
