Abstract
Transplants of cabbage (Brassica oleracea L. Capitata group) grown in growth chambers under continuous illumination of 310 μE m−2sm−1 (21.5 ± 1.1 klx) and temperature of 20 ± 1°C developed tipburn-like symptoms on young leaves within 8 to 14 days when maintained at 82% but not at 52% relative humidity (RH). Plants had larger leaves and greater fresh and dry weights at 82% than at 52% RH.
Abstract
Jojoba (Simmondsia chinensis (Link) Schneider) until recently was a relatively unknown Sonoran Desert shrub. Realization that the unique liquid wax in the seed could be substituted for the oil of the endangered sperm whale and that the plant could be grown with relatively small amounts of irrigation water has stimulated much interest among researchers in arid regions throughout the world. Major research programs on the domestication of jojoba are being conducted in the Department of Plant Sciences of the University of Arizona and the Department of Botany and Plant Sciences of the University of California-Riverside. Research programs are also underway at the Ben-Gurion University at BeerSheva, Israel, by state and federal agencies in Sonora and Baja California, Mexico, and in a number of other countries with arid and semi-arid regions. An International Committee on jojoba was formed in November, 1972 and 3 international conferences on jojoba have been held to date. The 4th international jojoba conference is scheduled for November 5-7, 1980, in Hermosillo, Sonora, Mexico.
