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 ...
Wu, M.J., Zacarias, L. and Reid. M.S., 1991. Variation in the senescence of carnation (Dianthus cao,ophyllus L.) cultivars. II. Comparison o f sensitivity to exogenous ethylene and of ethylene binding. Scientia Hortic., 48:109-116. Flowers o f the 'Sandra' and "Chinera" cultivars o f carnation (Dianthus caryophyllus L. ) last about twice as long ( 14 days) as those o f 'Whi te Sim' cultivar (7 ...
Using a combination of approaches, three EIN3-like (EIL) genes DC-EIL1/2 (AY728191), DC-EIL3 (AY728192), and DC-EIL4 (AY728193) were isolated from carnation (Dianthus caryophyllus) petals. DC-EIL1/2 deduced amino acid sequence shares 98% identity with the previously cloned and characterized carnation DC-EIL1 (AF261654), 62% identity with DC-EIL3, and 60% identity with DC-EIL4. DC-EIL3 deduced a...
In tissue culture, high production cost of the products restricts their reach. Though tissue culture is a major strength in floriculture it is marred by pricing issues. Hence, we developed a complete regeneration low cost micropropagation protocol for an economically important floriculture crop, carnation (Dianthus caryophyllus L.). Successful regeneration of carnation from nodal explants on co...
The whole-genome sequence of carnation (Dianthus caryophyllus L.) cv. 'Francesco' was determined using a combination of different new-generation multiplex sequencing platforms. The total length of the non-redundant sequences was 568,887,315 bp, consisting of 45,088 scaffolds, which covered 91% of the 622 Mb carnation genome estimated by k-mer analysis. The N50 values of contigs and scaffolds we...
Cold treatment of donor carnation plants (Dianthus caryophyllus L.) at 4 C for 3 days or more resulted in a doubling in the percentage of excised, frozen shoot apices which survived freezing and a 6- to 7-fold increase in the percentage which formed leaf primordia or shoots. The optimal freezing parameters for both survival and differentiation were as follows: size of the shoot apex-two to thre...
Abscisic acid hastened senescence of carnation flowers and this was preceded by stimulation of accelerated ethylene production. Carbon dioxide delayed the onset of autocatalytic ethylene production in flowers regardless of treatment with abscisic acid. Flowers exhibited a low and transient climacteric of ethylene production without wilting while in 4% carbon dioxide and underwent accelerated et...
The present study deals with the cytological investigations on the meristematic root cells of carnation (Dianthus caryophyllus Linn.) grown in vivo and in vitro. Cellular parameters including the mitotic index (MI), chromosome count, ploidy level (nuclear DNA content), mean cell and nuclear areas, and cell doubling time (Cdt) were determined from the 2 mm root tip segments of this species. The ...
