Summary: | The conditions required for the use of the Scheduler plant stress meter in vine production, the interpretation of the stress values obtained and their changes under irrigated conditions, and the trends is quantity and quality as a function of stress values were studied in an experiment set up on the vine variety Nosztory Riesling grown on a high cordon with a growing area of 3 m2 on a sout-facing rendzina soil with a shallow fertile layer. The instrument automatically records the plant and air temperatures, the intensity of irradiation and the humidity. The plant stress value obtained range from 0-10. If the plant is over-supplied with water the value is 0, the critical value of the stress index for the development of quantity and quality is 3, values higher than this represent increasing damage to plant life processes as they approach the upper limit. Trends in stress values over a 2-year period indicate that late July - early August, the sprouting phase, is critical for the water supply of vines. |
