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.

Major anthocyanins from purple asparagus (Asparagus officinalis)

Phytochemistry, 2008
Two major anthocyanins (A1 and A2) were isolated from peels of the spears of Asparagus officinalis cv. Purple Passion. They were purified by column, paper and high-performance liquid chromatographic separations, and their structures were elucidated by high-resolution Fourier transform ion cyclotron resonance mass spectrometry (HR-FT-ICR MS), 1H, 13C ...

Degradation of Malathion, in Aqueous Extracts of Asparagus (Asparagus officinalis)

Journal of Agricultural and Food Chemistry, 2004
Malathion was incubated in water extracts of vegetables at various temperatures and pH, and the amount of malathion present over time was analyzed by a gas chromatograph with a flame photometric detector. Malathion was degraded to a nondetectable level in a 1% asparagus extract incubated at pH 7.4 and 37 degrees C for 4 h.

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

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 ...
