    Notes: Abstract. Mustard seedlings in the early stages of growth are sensitive to the presence of excess moisture, growth of the radicle and anthocyanin synthesis being retarded by water at a suction of less than 3 cm water for seedlings growing on a plane surface. This inhibitory effect commences at about 12-15 h from wetting of the seed. It can be counteracted by increasing the partial pressure of oxygen in the atmosphere or by de-coating the seed, suggesting that the inhibition is caused by a restricted flow of oxygen through the mucilaginous seed coat. The positive effect of gravity on anthocyanin synthesis in the developing seedling can be wholly accounted for in terms of the removal of excess moisture. This explanation largely accounts for the improved growth of the root, but a tonic effect of gravity on root growth can also be discerned.

    Notes: [Auszug] Seeds of Lepidium sativum L. cv. Curled were moistened with 0.1 mM CaCl2, pH6.5, and left for 20 h at room temperature in normal lighting conditions. Seeds which were at a uniform stage of germination?the testa having split open but before the emergence of the radicle?were then placed with the ...

    Notes: [Auszug] Seeds of white mustard, Sinapis alba L., were moistened with 0.1 mM CaCl2, pH 6.5, and left to swell for about 4 h. Seeds of uniform size were then selected and placed on circles of Whatman No. 1 filter paper in 140-mm plastic Petri dishes containing CaCl2 solution. The treatments consisted of one ...
