Callus regeneration and polyploidy induction of Allium cepa L var. Bima Brebes using oryzalin

Doubled haploid production from Spanish onion (Allium cepa L.) germplasm: embryogenesis induction, plant regeneration and chromosome doubling

The use of doubled haploids in onion breeding is limited due to the low gynogenesis efficiency of this species. Gynogenesis capacity from Spanish germplasm, including the sweet cultivar Fuentes de Ebro, the highly pungent landrace BGHZ1354 and the two Valenciana type commercial varieties Recas and Rita, was evaluated and optimized in this study. The OH-1 population, characterized by a high gyno...

Assessment report on Allium cepa L., bulbus

Quercetin from shallots (Allium cepa L. var. aggregatum) is more bioavailable than its glucosides.

The lipophilic character of quercetin suggests that it can cross enterocyte membranes via simple diffusion. Therefore, it should be more bioavailable than its glucosides, which require preliminary hydrolysis or active transport for absorption. However, the published human studies show that quercetin is less bioavailable than its glucosides. Assuming that low bioavailability of quercetin aglycon...

Evaluation of callus induction and plant regeneration in Citrullus colocynthis (L.) Schrad. Sormeh Gharehmatrossian*

In the present study, small segments of cotyledon, apical bud, hypocotyl, and root of 10-day-old seedlings were isolated and transferred to Murashige and Skoog (MS) base medium with different treatments of phytohormones. Two media were used for apical bud culture: MS with indole-3-acetic acid (IAA) and kinetin (Kin) (1 mg/l) and the other medium, MS with double vitamin of MS and 6-benzylaminopu...

Callus Induction and Shoot Regeneration from Epicotyl Explants of Ethnomedicinally Important Caesalpinia bonduc (L.) Roxb

An efficient plant regeneration method was established for Caesalpinia bonduc (L.) Roxb. by culturingimmature epicotyl explants. Morphogenic calli were initiated from 96% of epicotyl explants on MS mediumsupplemented with BA (6-benzylaminopurine) 4.0 mg/l and NAA (Naphthalene acetic acid) 1.0 mg/l. The calliformed were excised and subcultured on MS medium fortified with 1 mg/l...
