Abstract
In the carrot case, which is an allogamous species, due to its protandry suitable for insect pollination, in order to assure the necessary pollen for obtaining of the comercial hybrid seed, it is compulswy a synchronism during the flower phenophase in male sterile and male fertile lines used as partners in the hybridization process. Our investigations aimed to establish the receptivity period of the stigma for pollination according to the morphological flower type (hermaphrodyte one, petaloid one or brown anthers one) and temperature conditions. Experiments were carried out during the 1997- 2006 period, the biological material consiting in 9 inbreed lines, namely 3 for each flower type. On each plant, summing up 15 for each line were manually pollinated the flowers located on 3 equivalent inflorescences having a simultaneous blossom.
