Advances in Somatic Embryogenesis in Vanilla (Vanilla planifolia Jacks.)

2022
Somatic embryogenesis is an in vitro plant morphogenetic process due to cell totipotentiality to induce shoot regeneration. To induce this proliferation pathway, we used auxins such as 2,4-dichlorophenoxyacetic acid in combination with cytokinins. There are numerous somatic embryogenesis protocols for a great diversity of plants, including orchids, but

The beautiful hills: half a century of vanilla (Vanilla planifolia Jacks. ex Andrews) breeding in Madagascar

Genetic Resources and Crop Evolution, 2021
An ambitious vanilla (Vanilla planifolia Jacks. ex Andrews) breeding program was started in Madagascar in the early 1950s to control Fusariosis, a serious crop disease caused by the soil fungus Fusarium oxysporum.

Micropropagation and In Vitro Conservation of Vanilla (Vanilla planifolia Andrews)

2009
Vanilla (Vanilla planifolia Andrews (syn. V. fragrans Salisb.), a source of natural vanillin, plays a major positive role in the economy of several countries. A native to the Central America, its primary gene pool is threatened by deforestation and over collection that has resulted in disappearance of natural habitats and wild species.

Microencapsulation of vanilla (Vanilla planifolia Andrews) and powder characterization

Powder Technology, 2018
Abstract Natural vanilla extract (NVE) and synthetic vanilla extract (SVE) were microencapsulated by spray-drying, using whey protein concentrate (WPC) as wall material. Physicochemical properties, volatility profile, vanillin concentration and antioxidant activity were evaluated by measuring total polyphenols, the inhibition of radical scavenging ...

INTERRELATION OF CURING AND BOTANY IN VANILLA (VANILLA PLANIFOLIA) BEAN

Acta Horticulturae, 2004
The fruit of the climbing orchid Vanilla planifolia (vanilla bean) is used for the commercial production of the prized vanilla flavor, consisting of vanillin and other numerous flavor compounds, with the use of a curing process. However, present curing methods yield only a fraction of the vanilla flavor from flavor precursors in green beans. Studies on

Protocols for Biotechnological Interventions in Improvement of Vanilla (Vanilla planifolia Andrews.)

2016
Vanilla (Vanilla planifolia Andrews (syn. V. fragrans Salisb.), a native of Central America, is the primary source of natural vanillin and plays a major role in the global economy. The gene pool of vanilla is threatened by deforestation and overcollection that has resulted in disappearance of natural habitats and wild species.

On the Life-History of Vanilla planifolia

Botanical Gazette, 1947
1. In the orchid Vanilla planifolia the microspores do not remain united to form compound grains, massulae, or pollinia, but lie free inside the anther. The pollen grains are shed at the two-celled stage. 2. The nucellus shows a greater development than in most other orchids, and the nucellar cells at the chalazal end persist even in the mature seed. 3.

Identification of Novel Orosensory Active Molecules in Cured Vanilla Beans (Vanilla planifolia)

Journal of Agricultural and Food Chemistry, 2009
Sequential application of solvent extraction, gel permeation chromatography, and HPLC in combination with taste dilution analyses, followed by LC-MS and 1D/2D NMR experiments, led to the discovery of seven velvety mouth-coating molecules in cured beans of Vanilla planifolia . Among these, 5-(4-hydroxybenzyl)vanillin, 4-(4-hydroxybenzyl)-2-methoxyphenol,

A Study of Vegetative and Floral Morphology of Vanilla Planifolia and Vanilla Tahitensis

Journal of Non-Timber Forest Products, 2011
Vanilla planifolia is the widely cultivated species of Vanilla and Vanilla tahitensis is cultivated to a limited extent. Comparative study of vegetative morphology and floral morphology of the two species has shown that the two species, even though have got almost similar appearance, they show significant difference in some characters.

Hyperhydricity-Related Morphologic and Biochemical Changes in Vanilla (Vanilla planifolia)

Journal of Plant Growth Regulation, 2009
Shoot cultures of vanilla (Vanilla planifolia) showed a progressive change toward hyperhydricity syn- drome (HHS) leading to the necrosis of shoot buds when transferred to liquid medium of shake-flask type from solid (gelled) medium (S). HHS was also associated with severe damage at cellular and subcellular levels, an increase in free polyamines (PAs ...
