In the production and breeding of Chrysanthemum sp., shoot branching is an important quality aspect as the outgrowth of axillary buds determines the final plant shape. Bud outgrowth is mainly controlled by apical dominance and the crosstalk between the plant hormones auxin, cytokinin and strigolactone. In this work the hormonal and genetic regulation of axillary bud outgrowth was studied in two...

The most widely used gene editing technology-the CRISPR/Cas9 system-employs a bacterial monomeric DNA endonuclease known as clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (Cas9) and single-guide RNA (sgRNA) that directs Cas9 to a complementary target DNA. However, introducing mutations into higher polyploid plant species, especially for species without g...

to study the effect of nitric oxide on longevity and some qualitative characteristics of cut carnation flowers (dianthus caryophyllus cv. nelson), cut flowers were treated for 48 hours with sodium nitroprusside (snp) as a source of no° donor at four concentrations (0, 20, 50 and 100µm) alone and in combination with other such ethylene inhibitors as thidiazuron and sucrose in a completely random...

this experiment was conducted in national institute of ornamental plants for extending vase life of anturium andranum cv. climax cut flowers. experiment was done based on completely randomized design (crd) with three replications and three cut flowers per replicate. treatments included volk oil emulsion wax coating (10, 20 and 30 percent), thyme oil (100, 150 and 250 ppm), salicylic acid (200, ...

Pyrethrins are terpenoid esters derived from the flowers of Chrysanthemum cinerariifolium. The pyrethrin family includes six similar compounds containing a cyclopropane core, named pyrethrin 1 and 2, cinerin 1 and 2 and jasmolin 1 and 2. Pyrethrins both repel and kill insects by delaying the closure of voltage-gated sodium ion channels in the nerve cells. The insecticidal and insect repellent p...

In any waste management process, the 3 R’s, i.e., Recycling, Reuse and Recover play a very important role. The present work focuses on collection, handling, usage of flowers. A large volume flower generated daily at Tumakuru is improperly disposed in open places or dust bins finally reaches landfill along with other municipal solid wastes. As part India’s Swachh Bharat programme, this paper giv...

Nitric oxide (NO) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. The research on the application of NO to postharvest preservation of flowers and fruits shows great promise in recent years. However, the physiological mechanism of exogenous NO to affect cut flowers is not very clear, and NO donor treatment protected plants from damage by increasing ...

Flos Chrysanthemi, dried flower of Chrysanthemum morifolium Ramat, has drawn much attention recently owing to its potential beneficial health effects for human. Flos Chrysanthemi products are usually taken orally and metabolized by intestinal microflora. However, there has been no investigation of the comprehensive metabolic profile of the Flos Chrysanthemi extract by intestinal flora owing to ...

Rose (Rosa hybrida L.) is one of the mostly cultivated cut flowers in Iran and around the world. The study was carried out to increase the vase life and quality of cut rose ‘Grand Prix` and ‘Avallanche` by using various floral preservative solutions. Floral preservative solutions were AgNO3, 8-HQS, nano silver and distilled water. Treatments were compared with tap water as control. The experime...
