Abstract EN
-Two concentrations (10-5M and 10-3M) of both GA3 and 2,4-D were used as foliar spray to evaluate the response of date palm (Phoenix dactylifera L.) cv.
Khedri seedlings.
They affected some of the anatomical characteristics of the first leaf emerging after the beginning of the spray.
The high concentration of GA3 increased the size of the midrib and its vascular bundle numbers.
Both low and high concentrations of 2,4-D inhibited the formation of the midrib.
2,4-D in both low and high concentrations decreased the number of vessels in both protoxylem and metaxylem and also decreased their diameters, where as GA3 in low and high concentrations have less effect on the number of vessels and its diameters.
GA3 in high concentration increased the number of vascular bundles in 1mm long of the leaf blade, while 2,4-D in low and high concentrations decreased their numbers.
10-3M of 2,4-D increased the size and layers of special hypodermal cells.
