Electroporation modulates the embryogénie responses of asparagus (asparagus officinalis l.) microspores

Protoplasma, 2001
Microspores of three genotypes of Asparagus officinalis L. were mechanically isolated without affecting their viability and were submitted to electric fields in order to modulate their competence for embryogenesis. When a constant pulse length and various field strengths (250, 500, 750, 1000, 1500, and 2000 V/cm) were tested, the viability of electro ...

An Antifungal Saponin from White Asparagus ( Asparagus officinalis L) Bottoms

Journal of the Science of Food and Agriculture, 1996
An antifungal saponin was isolated from the bottom cut of white asparagus (Asparagus officinalis L), which is unusable in food processing. The structure of the saponin was identified as 3-O-[{α-L-rhamnopyranosyl (1 → 2)} {α-L-rhamnopyranosyl (1→4)}-β-D-glucopyranosyl] (25S) spirost-5-ene-3β-ol from chemical and spectral data.

Identification of Sensory-Active Phytochemicals in Asparagus (Asparagus officinalis L.)

Journal of Agricultural and Food Chemistry, 2012
Sensory-directed fractionation of extracts prepared from raw and cooked asparagus (Asparagus officinalis L.), respectively, followed by LC-TOF-MS, LC-MS/MS, and 1D/2D-NMR experiments revealed the chemical structures of nine bitter tasting mono- and bidesmotic saponins as well as the previously not reported 1,2-dithiolan-4-carboxylic acid 6-D-α/β ...

Micropropagation of Asparagus (Asparagus officinalis L.)

1992
Asparagus, a member of the family Liliaceae, is a perennial of which the spears or growing stems are eaten. The perennial structure of the plant is a crown constituting a ramified rhizome formed by the consecutive initiation and development of buds and storage roots. Vegetative propagation by fractionation of the crown is possible on a small scale, but

Synthetic Seeds of Asparagus Officinalis L.

2001
There are numerous studies on in vitro clonal propagation of plant species. Asparagus (Asparagus officinalis L.) is dioecious and highly heterozygous. The plants are usually raised from seeds and the resulting seedlings contain equal proportions of male and female plants. Male plants are desirable because of their higher spear yield. Clonal propagation

Sex determination and differentiation in Asparagus officinalis L.

Plant Science, 1991
Abstract The paper summarizes the coordinated researches conducted by three Italian groups in the area of sex determination and differentiation in the dioecious species Asparagus officinalis . Morphological evidence indicates that sex differentiation in Asparagus consists essentially of selective abortion of gynoecium or androecium of initially ...

Genetic Transformation in Asparagus officinalis L.

1996
Asparagus officinalis L. is a perennial monocotyledon, a member of the Liliaceae family. It grows in temperate climates and under subtropical conditions. Growth of spears normally takes place in sandy soils. There are two culture types: the white asparagus, in which the spears are harvested from earthed up plants, where spears are cut at the crown ...
