This research was carried out to study the effect of three different sowing dates (15 th Oct., 15th Nov and 15th Dec.) and two vernalization treatments ( 5 °C and -20 °C ) on growth and some chemical components of Beta vulgaris L. cv. Univers leaf under Ismailia Governorate conditions. The obtained data are summarized as follows: -The highest values of plant height, number of leaves/plant, fresh and dry weight per plant, chlorophyll a, b, and a + b were shown at 15th October treatment. The contrary trend was found at 15th Dec. Furthermore, reducing sugars, total phenols and auxin like-substances were increased with 15th Dec. treatment and decreased by 15th Oct. treatment. Growth parameters, chI. a, b, a+b, a/b, reducing sugars, total phenols and auxin like-substances differed according to the used cooling treatments compared with the control. All of the used cooling treatments decreased auxin like-substances, reducing sugars at 90 days from sowing and total phenols at 90 and 120 days after sowing in comparison with the control.
