Selecting asparagus plants as sources of haploids

Euphytica, 1973
The frequency with which haploid asparagus plants are found amongst multiple seedlings is shown to depend very largely upon which female plant is used as a source of seed. The implications of this observation particularly in relation to the accumulation of haploids and their utilisation in breeding F1 hybrid asparagus are briefly discussed.

Identification of plant semiochemicals and evaluation of their interactions with early spring insect pests of asparagus [PDF]

open access: yesJournal of Plant Interactions, 2016
Information is lacking on the chemical ecology of asparagus, and knowledge about the effects of its volatile emissions on its associated early season pest species is completely absent.

Photosynthesis in Developing Asparagus Plants

Australian Journal of Plant Physiology, 1975
The gas exchange characteristics of asparagus shoots at various stages of development are described. Reassimilation in spears conserved 50-100% of the carbon dioxide produced in respiration. Refixation was influenced by light intensity and CO2 concentration in the surrounding air, but not by oxygen concentration.

HERBIVORE INDUCED PLANT VOLATILES OF ASPARAGUS (ASPARAGUS OFFICINALIS L.) AND THEIR ATTRACTION TO NATURAL ENEMIES OF KEY ASPARAGUS PESTS [PDF]

open access: yes, 2018
"Asparagus production in Michigan is limited in longevity, productivity, and market value by two key monophagous insect pests, the asparagus miner (Ophiomyia simplex Loew) (Diptera: Agromyzidae) and common asparagus beetle (Crioceris asparagi L ...

Somatic embryogenesis and plant regeneration from protoplasts of asparagus (Asparagus officinalis L.)

Plant Cell Reports, 1990
Protoplasts were isolated from embryogenic calli of Asparagus officinalis L. cv. Mary Washington and cultured in 1/2 MS medium with 1 mg/l NAA, 0.5 mg/l zeatin, 1 g/l L-glutamine, 0.6 M glucose and 0.1% Gellan Gum. Protoplasts started to divide after 3-4 d of culture and formed visible colonies after 30 d of culture. The percentage of colony formation (
