Exempel på endosperm

• As a rule the embryo is very small and surrounded by abundant endosperm. 

• In cases where the embryo has stored reserve food within itself and thus provided for self-nutrition, such endosperm as remains in the seed may take on other functions, for instance, that of water-absorption. 

• The formation of endosperm starts, as has been stated, from the endosperm nucleus. 

• The function of the endosperm is primarily that of nourishing the embryo, and its basal position in the embryo-sac places it favourably for the absorption of food material entering the ovule. 

• This apparently profitable machine permitted the miller to efficiently separate wheat flour into three components: bran, germ and endosperm. 

• The endosperm has a very thick peripheral cell wall (cw).

• The cytokinin or ethylene requirements for overcoming thermoinhibition of lettuce germination can also be eliminated or diminished by removing or weakening the endosperm.

• Or does the radicle elongate to the extent of pushing against the endosperm before endosperm degradation begins?

• An alternative explanation is that endosperm softening requires more than mannan degradation.

• This suggests that these storage polymers are responsible for the shape of the typical endosperm spectrum.

• As described above, the endosperm of the mature grain is packed with storage polymers rich in carbohydrate, protein and lipid.

• Cellular membrane integrity was studied in developing endosperm during differentiation and maturation.

• At stage 8, the endosperm changed from a liquid to viscous consistency and occupied only 50% of the seed volume.

• After 28 d, embryos had grown to 0.6 mm2 and occupied nearly 60% of the mucilaginous endosperm within which the embryo develops.

• A very thin endosperm (es) surrounds the embryo, leaving spaces of free water (w) in between.

• The size of the endosperm that contains essential protein, starch and other nutrients is an important criterion for crop breeding programmes.

• As the most important source of staple grains, the endosperm is measured for a phenotypic trait of interest.

• Statistical methods for dissecting triploid endosperm traits using molecular markers : an autogamous model.

• Rather, a stimulus released from the cotyledon is more likely to induce the major cell wall degrading enzyme, endo- mannanase, within the endosperm itself.

• Naked embryos were sensitive to imbibitional stress, whereas embryos with an intact, thick-walled endosperm were not.
