demonstration production of fast neutron-irradiated Columbia Col-0 Arabidopsis in minimal space. Photos
taken August 25, 2000, 57 days after planting.
Views of upper shelf of a double-decker
ArabiSun lighting system at LEHLE SEEDS Round
Rock Texas production growth room RR3 at 24 C. The shelf shown contains a 4 x 5
growing systems fitted with 17.5 inch tube stakes.. Shelf contains a total of 180
pots each containing 4 plants for a total of 720 plants. As the lower shelf contains
an additional 20 ArabiPatch containers configured similarly, the ArabiSun double-decker,
which takes up less than 2.7 square feet of floor space, is shown here growing a total of
1,440 Arabidopsis plants (360 pools of 4).
Note that each tube stake is fitted with an
ArabiTrap seed trap about 4 cm from the base of the
tube stake. A thin film with a hole to allow inflorescence penetration is held in
place by the
orange ArabiTrap ring. The ArabiTrap seed trap helps prevent shattered seed from
to the medium surface.
The image at top shows an overall view of
plants growing on the top deck of an ArabiSun lighting system. Note that all tube
stakes are filled with maturing inflorescences from 3-4 plants.
Due to extended length (17.5 inches)
of the tube stakes used here, only a few of these Columbia plants will grow out the top of the
tube. By using a longer tube stake, there is less need to cut or trim the tops of flowers protruding from the
tops of the tube stakes. As shown in the close-up photo on
lower right above, flower debris collects on the ArabiTrap film. Note that the
absence of seeds at the film layer of the ArabiTrap reflects the fact that very few
Columbia ecotype siliques have shattered under these growing conditions. Thus, with
non-shattering ecotypes such as Ws-2 or Col-0, the use of a ArabiTrap seed collector
is not necessary.
