“…Further, GA accumulation and degradation of ABA in spring releases bud dormancy, and temperature becomes the major controlling factor in hormonal regulation. Application of GA impacts positively the post-harvest longevity of grass like Miscanthus sinensis [150].…”

Seasonal dormancy is an adaptive mechanism where plants suspend growth and become physiologically inactive to avoid extreme environmental conditions. Environmental factors like temperature, photoperiod, nutrients, and soil moisture control plant growth and development through various complex molecular mechanisms. Crown and seed dormancy of plants are mostly influenced by day length and temperature. Genes and physiological pathways triggered by these two factors along with genotype variability are some targets to manipulate seasonal dormancy. There is genetic variation in the depth and duration of seasonal dormancy. Therefore, their genetic manipulation is possible. Manipulations of summer and fall dormancy are relatively easier compared to winter dormancy because plants require protection of their apical meristem from freezing temperatures and limited water supply. Genetic factors that regulate seed dormancy may also have regulatory role for seasonal dormancy of the maternal plants. Limited genetic and genomic information are available for seasonal dormancy in herbaceous perennial species. Knowledge of genes controlling seasonal dormancy of eudicots, forest trees, and horticultural crops could be interpolated to explore possible dormancy mechanisms in perennial forages. This study reviews current knowledge of seasonal dormancy of herbaceous forages emphasizing the genetic and physiological context that would be valuable to breeders and plant biologists to expand the production season of perennial species by developing non-dormant and semi-dormant cultivars.

The preservation of floral stems aims to prolong durability, maintain quality and reduce losses after harvesting, leading to a longer shelf life and commercialization of these products. In that there is a storage period, especially, of cut plants relatively short between seven and 15 days, this being one of the most important stages of the floricultural sector, ensuring the maintenance of the balance of the distribution market to the final consumer. The high perishability of the floral stems requires specific pre- and postharvest handling contributing positively to its conservation. In cut plants, such as the floral stems, there is an intensification of the physiological processes to maintain its metabolism right after harvest, when the plant leaves the plant and discontinues the supply of water and nutrients, resulting in the acceleration of its senescence. Thus, the understanding of the metabolism of the conservation of the floral stems gives the producer and the consumer products without changes in their aesthetic and qualitative aspect. Thus, the objective of the present study was to carry out a review of the post-harvest literature on cut flowers and ornamental plants, including pre- and post-harvest factors, solutions and preservative components.

The aim of the study was to evaluate the postharvest longevity of cut leaves of Viola odorata and determine their usefulness as a florist green. The research also involved the study of the influence of chemical compounds used as plant preservatives on the longevity of leaves of V. odorata. The leaf stalks of V. odorata were soaked in water or conditioned in a 200 mg·dm−3 solution of 8–hydroxyquinoline sulphate, or a 50 or 100 mg·dm−3 solution of gibberellic acid. After one day, the leaves were kept in water or 200 mg·dm−3 of 8–hydroxyquinoline sulphate. The leaves of V. odorata had a longevity of about 31 days in water. Both the conditioning in gibberellic acid and 8–hydroxyquinoline sulphate and the maintenance in 8–hydroxyquinoline sulphate reduced the vase life of cut V. odorata leaves. The application of conditioners resulted in a significantly greater reduction of the leaf mass. The Soil Plant Analysis Development value of the leaves was best affected by conditioning them in 100 mg·dm−3 gibberellic acid followed by keeping them in water. Cut leaves of V. odorata with water treatment may be used as a florist green.
