Receptivity of Pistilate Flowers of Mishrig Wad Laggai Date Palm
Grown under Khartoum Conditions
Dawoud H. Dawoud and Fatima A. Ahmed
Abstract:
This experiment was conducted at ALHalfaia in a private-owned Date Palm
Orchard in 1999, 2000 and 2001. Fourty-five date palms of Mishrig Wad
Laggaia (MWL) cultivar were selected and subjected to five treatments in
an RCBD. To determine the optimum length of time during which the female
flowers of Mishrig Wad Laggaia date palm remain receptive to
fertilization which is considered an important practice in date
production. The palms were pollinated after one, three, six, nine and
twelve days from spathe cracking. Delaying pollination to sixth, ninth
and twelfth day of female spathe cracking significantly reduced bunch
weight by 27%, 43% and 51%, respectively, as compared to bunch weight
obtained by pollination during the first day after spathe cracking. The
study revealed that flowers which remain receptive six days after spathe
cracking give the best yield and fruit quality.
