Rootstock Breeding for Stone Fruits

Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly notewor...

Particle sorting and stone migration due to frost heave.

33°N, long. 127°W, about 650 km west of Los Angeles. These holes will be drilled to about 300 meters, the depth depending on the maximum which can be attained with one bit because hole reentry will not be feasible. The drilling will test the hypothesis of ocean floor spreading (1) and the generation of long, linear, magnetic anomalies according to the Vine-Matthews hypothesis (2), relating them...

Production of artificial stone slabs using waste granite and marble stone sludge samples

In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...

Development of a High Temperature Controlled Atmosphere Quarantine Treatment for Pome and Stone Fruits

The research presented describes how a technology called Controlled Atmosphere Temperature Treatment System (CATTS), can be used as a quarantine treatment against insect pests of apples, pears and sweet cherries. High temperature forced air has not been useful for these temperate fruit because the heat dose required to kill the target insect pests (codling moth and western cherry fruit fly) cau...
