    Notes: [Auszug] So far as is known, these two methods have not been applied to the same plant material, and the present note is a preliminary account of the application of the methods to the seed proteins of Brassica nigra (L.) Koch, Brassicu oleracea L. and Brassica campestris L. On morphological and cytological ...

    Notes: [Auszug] Occasionally, commercial samples are obtained under the description of Paraguayan palm. The botanical name for this plant has been given as Acrocomia total. This palm is an important oil plant in Paraguay2 but no descriptions have been found of the histology of the fruit. Studies of the histology ...

    Notes: Summary The cotyledons of Sinapis alba L. seed are the storage organs and first photosynthetic organs. The development of the cotyledon cell contents was studied using electron and light microscopy. From the heart shaped embryo (11 days from petal fall) to the mature seed, nine stages were examined. Both types of protein grains (designated aleurone grains and myrosin grains) were found to form within vacuoles, but the mode of protein accumulation differed with each type of grain. Oil bodies were apparent with the EM from 18 days onwards, but could not be seen to arise from the ER. They were granular in appearance at early stages, but later became electron transparent.

    Notes: Summary The cells of the embryo of Sinapis alba L. include either aleurone or myrosin grains and all cells contain oil bodies. Aleurone grains and oil bodies are degraded during germination. The myrosin grains of each myrosin cell, on the other hand, gradually turn into one big vacuole containing the myrosin. Probably very little, if any, new myrosin is formed in the cotyledons and hypocotyl of the seedling after germination. No difference was found between aleurone and myrosin cells in the development of organelles. The cells of provascular bundles of the mature embryo contain different amounts of aleurone grains in different stages of development, and their organelles are more developed than those of all other cells.
