Seedling transplants produced for early fall and spring establishment of commercial vegetable crops in the Texas Lower Rio Grande Valley rapidly develop excessive shoot growth if field plantings are delayed. Therefore, several varieties of pepper, watermelon, muskmelon, and tomato transplants were treated at the 2-3 leaf stage by foliar spray with 0, 4, 8, or 12 ppm of the triazole growth retardant, uniconazole. The seedlings were field transplanted 3 weeks later. Total heights taken at the time of transplanting indicated significant varietal differences in responses to the treatments. After 60 days in the field, one of the 5 pepper varieties continued to express retarded growth. However, the uniconazole treatment stimulated early fruiting in 2 of the varieties. Tomato seedlings appeared to overcome the stunting within the first 60 days after transplanting while muskmelon and watermelon remained slightly dwarfed. Additional data on total growth and yield in response to the growth retarding treatments will be presented for each of the vegetable varieties.
The University of Arkansas established a new, replicated, woody ornamental plant evaluation program in 1999. Three sites were used across the state and these sites encompassed the three different USDA Plant Cold Hardiness Zones found in Arkansas, Zones 6, 7 and 8. In the first year, 17 different woody ornamental plants were established in the evaluation. Information obtained from performance in this evaluation will be used in Arkansas Select, a marketing program for customers and nurserymen in the state. Nonpatented and nontrademarked plant material will be made available for propagation purposes. Woody plants will be evaluated for 5 years and herbaceous perennials will be evaluated for 3 years.
