attributes.value: Arabidopsis plants were NOT grown in the presence of a mix of perennial and annual rye grass (commercial grass seed) until harvest at 3 weeks after planting.
attributes.tag: growth_protocol
attributes.value: Arabidopsis seeds were planted in 32 cm rows in a planting tray (64 x 32 cm) at a density of ~ 50 plants per row. Trays were covered with seran wrap and allowed to stratify for 3 days at 5C and were then moved to a growth chamber for one week until arabidopsis had sprouted. After 4 days, slices were cut in the seran wrap to allow the seedlings to harden to reduced humidity. After 1 week, the seran wrap was removed, and the trays were moved to the green house with an 18 hour day with natural and supplemental halogen lighting an a ~22C temperature. Arabidopsis seedlings were thinned to 10-12 plant per row and allowed to grow. Plants were watered daily as needed and once every week with 1/5 strengths Hoaglands soln.
