SYMPTOMS, YIELD, AND LEAF MINERAL COMPOSITION OF GREENHOUSE TOMATOES AS AFFECTED BY SOIL MOISTURE AND TOBACCO MOSAIC VIRUS1

Ernest L. Bergman, John S. Boyle
The difficulty in understanding and agreeing upon factors responsible for development of abnormal tomato fruits is mainly due to the many definitions and descriptions of symptoms. Furthermore, results of experiments involving only one factor have been reported even though more than one cause might be responsible for the same symptom. Broadbent (4) reviewed the many publications dealing with the various effects of tobacco mosaic virus (TMV) on tomatoes. The fruit disorder described as "internal browning" (IB) has been reproduced experimentally and predictably by inoculating tomato plants with TMV at specific times (3). It also has been suggested that late inoculation of tomato plants with TMV will affect the mineral composition of these plants (1).

Previous experiments involving TMV inoculation of tomatoes under field conditions (2) led to the belief that soil moisture might have a strong influence on the severity of visual fruit symptoms. Based thereon experiments were conducted under greenhouse conditions with the tomato cultivar Tuckcross V, a greenhouse type, to see what effect low and high soil moisture in combination with early or late TMV inoculation would have on yield, visual symptoms and leaf mineral composition.
