Abstract

This investigation was carried out during 1994/1995 and 1995/1996
winter seasons in Mallawi Agrir::ultural Research Station Ei·Minia
Governorate, Egypt, to study chemical characters of carrot cv. Balady
Selected and Chantenay Red Cored .. The experimental design was split plot with six replicates. Data of the two seasons were combined. The varieties treatments used occupied the main plots however, growth periods were in the sub plots. Obtained results showed that 1- Dry matter percentages of root and tops of Chantenay Red Cored were higher than those of Balady Selected, and they increased by increasing the plant age. 2· The Chantenay Red Cored had higher lotal soluble solids content in root comparing with Balady Selected. 3· Reducing, non-reducing sugars and total sugars contents of roots of Chantenay Red Cored and Balady Selected carrot varietes were found 10 increase as plant age advanced. 4· Anthocyanin pigment content in roots of Balady Selected carrot variety increased by increasing plant age.
5- Carotene pigment of Chantenay Red Cored root increased by plant aging.
