Quantitative real-time PCR (qPCR) is a popular and powerful tool used to understand the molecular mechanisms of flower development. However, the accuracy of this approach depends on the stability of reference genes. The capitulum of chrysanthemums is very special, which is consisting of ray florets and disc florets. There are obvious differences between the two types of florets in symmetry, gen...

Floriculture is among Kenya’s top foreign exchange earners. Gladiolus is one of the four famous cut flowers in the world whose popularity in Kenya is attributed to its heat tolerance, many spike forms and color combinations. However, the perishable nature of the flower renders it vulnerable to huge post-harvest losses. The study aimed to evaluate pulsing effect of cut Gladiolus</em...

tuberose aesthetically and commercially is an important flower that its importance is due to its potential for trade of cut flower, long vase life and essential oil industry. it is cultivated commercially by bulbs is needed to their storing properly after the harvest and quiescence to increase yield and flowering quality so that can be regulated flowering time according to market. experiments w...

The formation of unisexual flowers in maize requires the selective elimination and sexual maturation of floral organs in an initially bisexual floral meristem. Elimination of pistil primordia occurs in the primary and secondary florets of the tassel spikelets, and in the secondary florets of ear spikelets. Ill-fated pistil cells undergo a cell death process associated with nuclear degeneration ...

The reduction in shelf-life and nutritional value of cauliflower florets are the most vital problems during cold storage. This research was performed to explore impact pre-harvest foliar implementation proline (PR), methionine (MT), melatonin (ML), at a rate 25 mg.L−1, on active composites (cv. ‘Arasya’) stored 10 °C for 14 d. obtained results exhibited that from treated plants with PR, MT, ML ...

Materials for wrapping surgical dressings were studied by a method which measured the recontamination rate in packs stored for periods of up to several weeks. Of the materials tested a thick crêpe paper was better than calico and balloon cloth fabrics. Dressings wrapped in paper were not significantly contaminated after storage in dusty places for periods of up to three weeks. For added protect...

BACKGROUND AND AIMS Why are sterile anthers and carpels retained in some flowering plants, given their likely costs? To address this question, a cryptically dioecious species, Petasites tricholobus, in which male and female plants each have two floret types that appear pistillate and hermaphroditic, was studied. The aim was to understand the function of sterile hermaphroditic florets in females...

Less than 10% of the acid p-nitrophenylphosphatase activity of plant extracts was sedimentable under a variety of conditions including zonal centrifugation. The sedimentable fraction did not show the latency properties characteristic of animal lysosomes. We conclude that, at least operationally, plant acid phosphatase is a soluble enzyme and that it is not suitable as a lysosomal marker. The pl...

The ascorbate content declined rapidly in broccoli (Brassica oleracea L. var. italica) florets, but not in the stem tissue, during post-harvest senescence. Ascorbate peroxidase (APX), ascorbate oxidase (AO), l-galactono-1,4-lactone dehydrogenase (GLDH), monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), and glutathione reductase (GR) were investigated in gene expression a...
