Glossary & Units

Albinism: Mottled white fruit that is insipid and tasteless in flavor – a condition usually associated with excess nitrogen use. Some varieties are more sensitive.

Anthocyanin: A pigment that reflects the red to blue range of the visible spectrum and which colors fruit.

Antioxidants: Molecules that inhibit the oxidation of other molecules and so prevent or delay cell damage. Antioxidant-rich fruits in the diet help strengthen the ability to fight infection and disease in humans.

Calyx: The outer ring of the flower parts attached to the stalk.

Crown: The short thickened stem (called a “crown”) which has a growing point at the upper end and which forms roots at its base (see Agronomical principles /Growth stages/Figure 1).

Day Neutral Strawberry: See Agronomical principles and Everbearer, below.

Distal: The end of the strawberry furthest away from the calyx and stem.

Everbearer: Also known as day-neutral strawberries, these types produce ‘perpetual’ berries right though from early summer to autumn.

Folate: Folic acid - also known as vitamin M, vitamin B9, vitamin Bc (or folacin), pteroyl-L-glutamic acid, and pteroyl-L-glutamate) - is a form of the water-soluble vitamin B9.

Hill (Plasticulture) System: See Production Systems.

Matted Row System: See Production Systems.

Necrosis: Injury that results in the premature death of cells.

Petiole: The stalk attaching the leaf blade to the stem.

Phenol: Natural compounds (including anthocyanins) that have antioxidant type effects and which have been linked with improved health.

Proximal: The part of the fruit closest to the calyx.

Pistils: The female parts of the flower.

Runners/Stolon: The stolons that branch out from the mother plant crown on which daughter plants are formed (see Agronomical principles /Growth stages/Figure 1).

Sepal: The leaves below the flower petals on the calyx.

Short Day Strawberry – see Production Systems.

Stolon: See ‘runners’ above.

Total Soluble Solids (TSS): The sum of the solids in solution. For practical reasons (it is an instant and easy assessment) the °Brix is usually used to approximate TSS content because the soluble sugars usually represent more than 99% of the soluble solids.

UNITS

The units used within this manual are largely those used and quoted by the authors or the source in their country of origin. Where applicable metric equivalents have been used.

All yields in this Strawberry Crop content are given in metric tonnes (1000kg); an American Ton is equivalent to 0.907kg.

1 lb/acre = 1.12kg/ha 1kg/ha = 0.89lbs/acre 

Converting mmol/l to mg/l

mmol/l = mg/l / atomic weight

mg/l = mmol/l * atomic weight
