摘要

The exact origin of the date palm (Phoenix dactylifera L.) has been lost in history. However, earliest evidence goes as far back as 4000 B.C. in Iran. Date palm is the second most important fruit crop in Iran with more than 185,000 ha of harvested areas, about 880,000 tons annual production and 94,585 tons fruit exported annually according to FAO (2007) which made it the second largest date palm producing country. About 400 among 3000 cultivars of date palm have been reported from Iran and in this regard it is placed first in the world. However, the date palm industry is not considered to be economical due to the use of different local cultivars and it is preferred, therefore to introduce some well-known and more productive universal cultivars. One of them is 'Deglet Noor' compared with 'Sayer' as a main cultivar of Khuzestan province located in southwest of Iran. 27 tissue-cultured plantlets were introduced and investigated at the Ahwaz Agricultural Research Station from 1990 to 2003 in a complete block design with three replications. The results showed that the survival percentages of 'Sayer' and 'Deglet Noor' cultivars were 96 and 70%, respectively. Yield, number of bunches, weight of a berries, water content and pulp to seed weight ratio of 'Deglet Noor' fruits were higher than for 'Sayer'. Number of strands per bunch, number of fruits per strand, length, diameter, volume, shape and color of fruits of both cultivars were approximately the same. However, total sugar concentration of 'Deglet Noor' and 'Sayer' fruits was 64.5 and 75.6%, respectively. Hence 'Deglet Noor' has good production and is recommended for Khuzestan province but its quality may be improved by using suitable pollen sources or by applying selected plant growth regulators.
