Abstract Adenium obesum (Forssk.) Roem. & Schult., popularly known as desert rose, has become a valuable ornamental plant. In floriculture, the production of hybrids is prioritized. Hence, knowledge on floral biology and sexual reproduction target species fundamental. The objectives this study were: (1) to test sucrose concentrations temperatures for in vitro germination A. pollen grains; (...

in vitro propagation of rose (rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including indian subcontinent. the development of new cultivars for commerce is faced with new challenges. in vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...

AGAMOUS-LIKE 24 (AGL24) is a key gene regulating floral transition, but its involvement in flower organ identity remains largely unknown. In this study, we found that RhAGL24 strongly related to petal and stamen development rose. Its expression increases rapidly at the primordium stage maintains high level until complete differentiation stage. silencing number of malformed petals decreases stam...

Pollen quantity, viability and germination of four genotypes of Rosa dumalis and R. villosa were investigated. The number of anthers per flower were 90.3 in genotype 4 (Rosa villosa) and 116.4 in genotype 1 (Rosa dumalis). Genotype 1 showed the highest pollen viability on the basis of both TTC and IKI tests. Most of the rose species are diploid but there are several species with higher ploidy l...

The purpose of this experiment is to compare the growth and water consumption efficiency five garden plants (marigold (Tagetes erecta ‘Red Brocade’), moss-rose (Portulaca grandiflora ‘Sun Rose’), dahlia (Dahlia sp. ‘Double Opra’), gazania (Gazania splendens ‘New Day’), Indian blanket (Gaillardia pulchella. Dance’)) during warmer seasons year under various levels drought stress based on field ca...

This experiment was carried out to evaluate the effect of silver nanoparticles pulsing treatment (0, 25, 75 and 125 mg L−1) on vase life and some postharvest physiological parameters of cut rose flower ʻHigh & Magicʼ in sucrose solution (0, 2 and 3%). This research performed as a factorial experiment based on a completely randomized design with three replications under 23 ± 2 °C, 60 ± 5% RH and...

Flower opening is a process that requires movement of petals from a closed position to a horizontal open position, while petal abscission requires cell-wall disassembly. Both processes are controlled by ethylene and require cell-wall modification at the junction (abscission zone) of the petal and thalamus to facilitate the movement or separation of petals. In the present study, a family of xylo...
