Mineral Nutrient Composition of Green and White Asparagus Spears
Mineral nutrients were determined in green and white ‘Jersey Giant’ asparagus (Asparagus officinalis L.) spears grown in 1991 near Booneville, Ark. Green spears had higher concentrations of tissue N, K, P, S, Na, and Zn; similar levels of Fe, Al, and Cu; and lower levels of NO3 than white spears grown under opaque plastic rowcovers or under sawdust mulch. Levels of Ca, Mg, and Mn were higher in...
متن کاملConstraints on Asparagus Production: The Association of Ophiomyia simplex (Diptera: Agromyzidae) and Fusarium spp
Production of asparagus (Asparagus offi cinalis L.) is globally constrained by the “early decline” syndrome. The primary causal agents of early decline include Fusarium proliferatum (Matsushima) Nirenberg, F. oxysporum Wollenw. f. sp. asparagi S.I. Cohen, and F. subglutinans Wollenw. & Reinking. These pathogens together contribute to Fusarium crown and root rot (FCRR). Damage to asparagus stems...
متن کاملChanges in Enzyme Activities During Postharvest Deterioration of Green Asparagus Spears
Fresh asparagus (Asparagus officinalis L.) deteriorates rapidly after harvest. Early enzymatic changes that follow harvesting of asparagus are important factors contributing to postharvest deterioration. We held asparagus spears at 25°C for up to 5 days after harvest and examined changes in the activities of Acid invertase (AI), Sucrose Synthase (SS), Glutamine Synthetase (GS) and Phenylalanine...
متن کاملChanges in phenylalanine ammonia-lyase activity and gene expression during storage of asparagus spears.
A cDNA clone coding phenylalanine ammonia-lyase (PAL) was isolated from a cDNA library prepared from asparagus spears (Asparagus officinalis L. cv. Welcome) using the reverse transcription-polymerase chain reaction (RT-PCR). The partial cDNA clone encoded an mRNA of 527 bp and the derived amino acid sequence was found highly homologous to PAL from rice, maize and barley. Northern blot analysis ...
متن کاملExtending the shelf-life of asparagus spears with a compressed mix of argon and xenon gases
Noble gases that form clathrate hydrates when dissolved into water and restrict water molecule activity can prolong the shelf life of fruits and vegetables. Physiological and physical aspects of asparagus spears treated with mixtures of compressed (1.1MPa absolute) argon (Ar) and xenon (Xe) (2:9 in partial pressure) were compared with controls under normal preservation in modified atmosphere pa...
