Preliminary studies on the RNA components of three strains of cucumber mosaic virus
(1975-11)
In investigations of the causal relationships between disease symptoms and virus infection of plants, three strains of cucumber mosaic virus (viz. N, Price's No. 6 and W) which caused different symptoms in several plant ...
Refractive index profile optimization in diffused graded index lenses
(1975-10)
Refractive index profiles resulting from simple diffusion processes in glass are calculated, and optimum choices of diffusion parameters are chosen from minimum error in approximating focusing refractive index profiles. ...
Ribosomal RNA metabolism in cucumber leaf mesophyll protoplasts
(1975-07-01)
Aspects of the metabolism of RNA have been studied in enzymatically isolated protoplasts from cotyledon and first leaf mesophyll tissue of two cultivars of cucumber. The first leaf mesophyll protoplasts incorporated ( ...
The isolation and culture of cucumber mesophyll protoplasts
(1975-03-01)
Large numbers of viable protoplasts were obtained from the first leaves of two cultivars of cucumber, Cucumis sativus L. cv. Ashley and China. Cell wall regeneration was observed in liquid culture within 3 days of isolation, ...
Early stages in cell wall regeneration of tobacco mesophyll protoplasts : An electrophoretic study
(1975-02-01)
The electrophoretic mobilities of isolated mesophyll protoplasts of Nicotiana tabacum var. Xanthi n.c. were measured using a whole cell electrophoresis apparatus. Changes in mobility were recorded at times during aseptic ...
A new waveguide switch/modulator for integrated optics
(1975)
A waveguide optical switch and/or modulator device is described that uses a single-mode waveguide version of the Mach-Zehnder interferometer. A mode selective branching waveguide is used for switching, and modulation can ...
Behavioural effects of electrical stimulation of the hypothalamus of the goldfish (Carassius auratus)
(1975)
Food-satiated goldfish were stimulated in tanks containing food on the surface of the water and on the bottom of the tank. Various components of the feeding response were seen, and complete feeding was observed, which was ...
