To study the adaptability and qualitative and quantitative properties of eight world commercial dates varieties in Iran (vegetative phase)

In order to study and evaluate the vegetative growth of eight commercial date varieties such as Khalas, Abou Narenja, Gosh Zabad, Fard (female), Abou Moan, Nabat Seif, Ashrassi and Helali which were derived from tissue culture using complete random block design, with eight treatment and four replications in five years from 1997 to 2001 in agricultural research stations in Iranshahr, Bam, hajiabad, Jahrom, Jiroft, Zabol, Shabankareh and Minab respectively. The vegetative growth characteristics of the trees including the hight of whole trees, the hight of trunk, the diameter of trunk, the number of offshoots produced by every tree, the percentage of living trees, shading area, the number of green leaves, the length of leaf, the wide of leaf, the number of leaflet on each leaf and the weight the leaf have been calculated. The results of experiment were compared by Dancan’s new multiple range test in 1 and 5 percent. method in area of one to five percent respectively. The results from statistical studies showed that the suitable varieties in Jahrom research station were Gosh Zabad, Abou Nranja, Abou Moan, Nabat Seif and Khalas. In Shabankareh station, the varieties such as Nabatseif, Abou Narenja and Goush Zabad were superior. The suitable varieties in Hajiabad station were Gosh Zabad and Abu Naranja. The varieties such as Gosh Zabad and abou Naranja were evaluated and measured as a first grade and the varieties like Ashrassi and Helali were in last grade with respect to the vegetative growth. In Jiroft station, the varieties like Abou Naranja, Gosh Zabad and Nabat Seif and in Bam station the varieties like Kalas, Abu Moan and Goush Zabad had the most vegetative growth. It has been observed that the varieties such as Ashrassi and Fard(Female) had the best yield and production. The most vegetative growth in Minab station was in Goush Zabad and Khalas varieties, and the least were in Helali, Ashrassi and Nabatseif. In Iranshahr station the varieties like Zahidi, Abu Narenja and Gosh Zabad had the most vegetative growth and Helali variety had the least. In Zabol station, the varieties such as Zahidi, Goush Zabad and Abou Naranja were in the first grade and the last grade were belonged to Ashrassi variety. and#8727.Member of scientific board agricultural and natural resoures research center of Fars, Shiraz.
