Effects of temperature and water availability on light energy utilization in photosynthetic processes of Deschampsia antarctica.

abstract：:A treatment period as brief as 8 h in 10(-3) M EGTA completely blocks gravitropism in 70-80% of the treated coleoptiles of oats (Avena sativa L. cv. Garry) without inhibiting growth. Only about 10% of the plants perfused in water failed to exhibit gravitropism. Subsequent perfusion of EGTA-treated plants with calcium ...
