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.

Breeding of Polyploid Asparagus (Asparagus officinalis L.)

Plant Breeding, 1991
AbstractAsparagus is especially suitable for polyploidy breeding. The aim is to develop clone‐based hybrid varieties, in particular male 4 × varieties. For this purpose, genetically divergent diploid idiotypes*) are subjected to mitotic or meiotic polyploidization.

the metabolism of l-asparagine in asparagus officinalis

International Journal of Biochemistry, 1980
Abstract 1. 1. l -Asparagine is present at a concentration ranging from 0.004–0.04 M in Asparagus officinalis. 2. 2. Sensitive radiometric techniques have been used to examine enzymes responsible for the synthesis and metabolism of l -asparagine in Asparagus. 3. 3.

Transgenic Asparagus (Asparagus officinalis L.)

2001
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 ...

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 ...

Mineral content modifications during ripening of asparagus (Asparagus officinalis, L.)

Plant Foods for Human Nutrition, 1996
The essential elements: calcium (Ca), magnesium (Mg), sodium (Na) potassium (K) and phosphorus (P) were analyzed in fresh asparagus to determine the effect of the ripening of the asparagus on the mineral content. Asparagus samples were classified in two groups by diameter (< 11 mm and > 14 mm).

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

An efficient particle bombardment system for the genetic transformation of asparagus (Asparagus officinalis L.)

Plant Cell Reports, 1997
The microprojectile bombardment method was used to transfer DNA into embryogenic callus of asparagus (Asparagus officcinalis L.) and to produce stably transformed asparagus plants. Embryogenic callus, derived from UC 157 and UC72 asparagus cultivars, was bombarded with tungsten particles coated with plasmid DNA that contained genes encoding hygromycin ...
