Early Field Detection of Bolting in Celery

Abstract

<jats:p>Growers of early stalk celery (<jats:italic>Apium graveolens</jats:italic> var. <jats:italic>dulce</jats:italic>) often experience financial losses due to bolting (the premature and rapid elongation of the main celery stem) in temperate regions. A method was developed to provide early warning of bolting in field-grown celery, on the basis of two criteria, one visual and one microscopic, for inflorescence development. Bolting could be detected 40 days after transplanting using the visual criterion, and as early as 30 days after transplanting using the microscopic criterion. Early detection of bolting using the visual and microscopic criteria provided celery growers with periods of, respectively, 25 days and up to 35 days to consider harvesting earlier, before the length of the celery stems exceeded commercial standards. This method could be effective in minimizing financial losses due to bolting when coupled with agro-economic studies.</jats:p>

Origin, evolution, breeding, and omics of Apiaceae: a family of vegetables and medicinal plants

“…[ 218 ] revealed that the vernalization requirement of carrot was controlled by a multiallelic digene. Previous studies found that annual and biennial celery cultivars bolt easily, and cultivars with strong bolting resistance are rare [ 169 , 219 ]. A single locus, Hb , was identified from F 2 hybrids and found to control the bolting time of celery [ 220 ].…”

Reducing Preharvest Bolting in Open-field-grown Cilantro (Coriandrum sativum L. cv. Santo) through Use of Growth Regulators

“…Similarly, fennel (Foeniculum vulgare) will bolt after being exposed to several photoperiod cycles for a minimum of 13.5 h (Peterson et al, 1993). Several other studies reported that celery (Apium graveolens) is a day-neutral species that is induced to flower by vernalization (Jenni et al, 2005), although LD conditions after vernalization treatments greatly reduced the time to bolting (Ramin and Atherton, 1994).…”
