This study was carried out in AL Swaida nursery during 2009 and 2010
seasons to study effect of time and grafting high are on the growth strength of
apple cultivars: Golden delicious، Stark rimson, Starking delicious. Results
showed that Golden de
licious preponderated on the other cultivars in diameter
average (9.06 mm) at 3cm above the grafting area (5cm above soil level). The
study also confirmed that Starking delicious showed significant superiority(p
<0.05) in term of growth strength on the other two cultivars when grafting was
carried at 5cm and 20cm above soil level and the best of leaf area (2862،89cm2)
was observed at 20 cm above the soil level when grafting took place in 31 of
August.

The study was performed in Barshin Research Station- General
Commission for Scientific Agriculture Research on the trees age of
13 in grafted with Golden Delicious Cultivar on three rootstocks
(seedless rootstock Malus domestica, vegetative strong
rootstock
MM109, and MM111 half strong rootstock) over the years
(2014.2015 ).The study focused on growth vigor (the stem
circumference above the grafted area ,crown size - the rate of
shoots length and productivity).
Biological characteristics and life table parameters of the two-spotted spider mite Tetranychus urticae (Koch) were studied when fed on leaves of two apple cultivars (i.e. Golden and Starking dilishz) under laboratory conditions 25±1 Cº, relative hum
idity 65±5% and 16L:8D. The intrinsic rate of increase (rm) by females of T.urticae was higher on leaves of Starking dilishz apple cultivar than on leaves of Golden dilishz apple cultivar (0.30, 0.27 female/female/day) respectively, while the generation time (T) and the time required for doubling the number of community mite (DT) were lower on leaves of Starking dilishz apple cultivars than on leaves of Golden dilishz apple cultivars (13.77, 2.3 days and 14.54, 2.55 days) respectively. The duration of the stages of growth from egg to adult female on leaves of Golden dilishz apple cultivar was longer than on Starking dilishz apple cultivars, where was (13.32 ± 1.15 and 12.22 ± 1.13), respectively, The Total fecundity on Golden dilishz apple cultivar was lower than on Starking dilishz cultivar (83.11 ± 8.91, 101.62 ± 15.48 eggs/female) respectively, The adult longevity on Golden dilishz leaves was lower than on Starking dilishz cultivar (15.33 ± 1.35, 17.14 ± 1.07 days) respectively, These differences on the apple varieties may be due to the chemical content and quality of the food and nature of the host tissue plant and the specifications can affect the rate of oviposition and development. and thus the Starking dilishz apple cultivars was more suitable for the development and reproduction of T. urticae compared with the Golden dilishz apple cultivar.
