The Araceae is a diverse family consisting of more than 100 genera and 1500 species of plants including several genera of growing significance as foliage ornamentals, such as Aglaonema, Caladium, Dieffenbachia, and Syngonium. Other aroids, such as Anthurium and Zantedeschia are commercially propagated for their attractive flowers; Pistia stratioites is considered a pestiferous aquatic weed, and jack-in-thepulpit (Arisaema spp.) is a well known woodland wildflower of temperate climates.
Fruit yield and quality were determined in field plots of tomato (Lycopersicon esculentum, Mill.) inoculated with Xanthomonas campestris pv vesicatoria (Doidge) Dye at the 3-4 true leaf stage (early inoculation), or 10 days after first fruit set (late inoculation), and in uninoculated control plots. Early inoculation reduced yields, especially of large-sized fruit. In one of 2 experiments, yield of large-sized fruit was also reduced by late inoculation. Bacterial spot on fruit was responsible for some marketable yield loss in both experiments. Sunscald was significantly increased in early inoculation plots in one of the experiments. No disease effects on crop maturity or total number of fruit harvested were found. Yield losses were more severe than could be accounted for by lost and diseased foliage alone.
Phenological stages of ‘Flora-Dade’ tomatoes are described using a nomenclature system to be used for tomato pest management. Two vegetative stages (TV1, TV2) are listed as well as 3 reproductive plant stages (TR1, TR2, and TR3). Vegetative stage TV1 describes plants 1–15–days old with 2–3 primary leaves. TV2 describes plants 6–39 days–old with 5–7 leaves. Reproductive stages (TR1 TR2, and TR3) cover plants 40–135 days–old, characterized by presence of flowers clusters, and fruit formation and ripening. Characteristics of each stage are discussed. A senescent stage (TS1) is present from 136–200 days after plant emergence.
Florida 1011, an inbred line of tomato (Lycopersicon esculentum Mill.) was developed at the Agricultural Research and Education Center in Homestead and Bradenton in cooperation with the H. J. Heinz Company. The line is designated Florida 1011 in recognition of its Southern Tomato Exchange Program (STEP) designation (3).
