An ovule culture technique has been established for barley that allows the regeneration of plants from zygotes. An average of 1.3 plantlets per ovule could be regenerated from more than 60% of the cultured ovules and about 75% of the regenerated plantlets developed into normal, fertile plants. The same regeneration frequencies were obtained in intact ovules(More)
An analysis of the noise floor owing to temperature-induced index fluctuations in the fiber of a dynamically biased interferometric fiber-optic gyroscope is presented. A comparison with shot noise indicates that, for a harmonic bias modulation, thermal noise in the fiber dominates for fiber lengths longer than ~1-2 km when practical source power levels are(More)
