Abstract: In browsing through issues of HortScience and the Journal, I am often seized with a wild fantasy about Galileo reporting the results of one of his experiments with falling bodies in the pages of one of our society journals.

Abstract: Abstract Antitranspirant chemicals Clear Spray (200 ml/liter) and Vapor Gard (50 ml/liter) significantly increased stomatal diffusive resistance in cineraria ( Senecio cruentus DC.) on hot days. Foliar applications of the antitranspirants were effective in reducing plant water stresses for a period of 4 weeks. These chemicals did not have a significant effect on stomatal diffusive resistance when no water stress occurred in the plants. Foliage sprayed with these chemicals was more attractive and plants required less watering to maintain vigorous growth.

Abstract: Pepper (Capsicum frutescens L. cv. Hot Hungarian Yellow Wax) and polebeans (Phaseolus vulgaris L. cv. Dade) were grown in an intensive production system with film mulch, broad-spectrum soil fumigation and trickle irrigation. Nitrogen was applied through the trickle irrigation tubes at 0.56, 1.12, 2.24, and 4.48 kg/ha per day for the pepper and 0.56, 1.12, 2.24, and 3.36 kg/ha per day (doubled 6 weeks after seeding) for polebeans. Potassium was applied at 0.83 times the N rate. The N and K were applied twice weekly for the polebean and with every irrigation for the pepper. Marketable pepper yields ranged from 59.6 MT/ha with the low fertilizer rate to 96.0 MT/ha with high fertility. Yield increases with increasing fertilizer rates were not as great with polebeans as with peppers but there was a trend for higher yields with increasing fertilizer rates.

Abstract: Everyone who grows plants is aware of the vital role of the environment and at almost every meeting of horticulturists papers are presented describing the effects of environmental factors on plant growth. However, the environment includes so many interrelated factors (light, water, temperature, CO2, mineral nutrition, air pollutants, and pests) that it often is difficult to decide which one is producing an observed effect on growth. For example an increase in temperature often is accompanied by an increase in transpiration which may produce plant water stress. Thus it is difficult to separate the direct effect of increasing temperature on biochemical processes from the indirect effects produced by increasing plant water stress. The only way in which the effects of environmental factors on growth and yield can be analyzed effectively is by growing plants in controlled environment laboratories (phytotrons) where a particular component of the environment can be varied while all the others are held constant.
