Allelopathy of Cress Germinated Seeds and Tomato Seedlings.

Failure of Root Tips of Tomato Seedlings Germinated from X-rayed Seeds to Grow in Vitro.

Histological studies of roots of Vicia faba and of Zea mays seedlings grown from seeds given a medium dose of soft x-rays, indicate considerable distortion and irregularity about the apical meristem and surrounding tissues after the first week of germination (7, 8). These are not apparent during the early part of germination when the radicles first appear; the meristem is relatively normal in a...

A comparison of intrinsic endoplasmic reticulum membrane proteins in maturing seeds and germinated seedlings of castor bean.

The intrinsic membrane proteins of the endoplasmic reticulum from endosperm of maturing and germinated seedlings of castor bean (Ricinus communis) were studied. Preparations were simultaneously subjected to two-dimensional polyacrylamide gel electrophoresis. At least 30 separate proteins were distinguished by staining the gels with Coomassie R-250. The characteristic protein profiles obtained f...

The Anti-Scorbutic Value of Dry and Germinated Seeds.

SCURVY is always a menace to any community of people who are separated from adequate supplies of fresh food, whether in tropical or arctic climates. Such it proved to be to our army in Mesopotamia in ]915 and 1916 (Mesopotamia Commission Report, 1917), especially among the Indian troops. In consequence of this outbreak, a group of investigators in this Institute undertook an investigation of fo...

Heterogeneity of catalase in maturing and germinated cotton seeds.

To investigate possible charge and size heterogeneity of catalase (EC 1.11.1.6) in cotton (Gossypium hirsutum L. cv Deltapine 62), extracts of cotyledons from different developmental ages were subjected to nondenaturing polyacrylamide gel electrophoresis and isoelectric focusing. Special precautions (e.g. fresh homogenates, reducing media) were necessary to prevent artefacts due to enzyme modif...
