Water fraction out of total fresh weight in young pea in the period before abortion of nodes due to cold

Range 80-86 Percent
Organism Pea Pisum sativum
Reference Bertrand Ney* and Claude Duthion, Timing of Reproductive Abortions in Relation to Cell Division, Water Content, and Growth of Pea Seeds, Crop Sci 33:267-270 (1993)
Method Cultivar Solara was grown in nonstressed conditions during three successive years, in 1988 and 1990 in a glasshouse in 7-L pots with 4 or 5 plants per pot, and in 1989 in the field with 50 plants m–2. At all nodes, abortion occurred before {approx}300 degree-days (base temperature of 0 °C) from the date of flowering of the node beyond this date, numbers of pods and seeds per pod remained constant at the node. During the initial 300 degree-days, embryo cellular divisions were active and then cell number plateaued. Water content varied between 0.80 and 0.86 g g–1 of fresh weight initially
Comments Abortion of node occurred within 300 degree-days of flowering. A degree day is a day in which base temperature dropped to 0 degrees celsius
