THE EFFECT OF METHANOL ON THE GROWTH AND CHLOROPHYLL CONTENT OF TOMATO AND PEPPER

The effect of methanol alone or in combination with glycine (0.2%) on growth of tomato plants – derived from seeds (cv.
Makedonia) or cuttings (Hybrid F1 Emperor) and pepper plants (cv.
P-13) and on chlorophyll content of their leaves was studied.
In both species methanol+glycine reduced plant height and increased root length and weight, leaf thickness and chlorophyll content.
In the case of tomato cuttings, 40 days after last spray, the plants died except those treated with methanol+glycine, which continued their growth, and their green color was intensified.
In tomato plants derived from cuttings and in pepper plants an increase in blooming and fruit number was observed.
When methanol was used alone, the results concerning the shoots were similar to those of control (untreated plants), while its effect on the roots was similar to that of the combination methanol+glycine.
