| This study was conducted during successive summer season of 2012 in the central laboratory for agricultural climate orchard , ministry of agriculture , at Dokki restrict ,Giza governorate in Egypt. Due to the lack of appropriate environmental conditions for the success of the grafting process during the period of vegetative growth, this research aimed to study the effect of different greenhouse covering materials ( glass, polyethylene and white net (control)) and day times ( 8 AM, 1 PM and 6 PM ) for providing optimum conditions of environmental parameters (light intensity, air temperature and relative humidity) for successful grafting process on mango seedlings during development of vegetative growth as well as the interaction between these factors. The results of variance analysis showed that light intensity and ambient air temperature were recorded the highest average values 40.6ºC and 46910 lux, respectively under polyethylene covering material at 1 PM. However, the lowest average values of air temperature and light intensity recorded 26.5ºC and 1666 Lux under white net and glass covering materials, respectively. In contrast, the relative humidity (RH) is decreased to reach 31% with polyethylene covering material. Stem length and leaf area recorded the greatest average values 21.7 cm and 249.8 cm2, respectively under glass covering material. Stem diameter and number of leaves recorded the greatest average values 0.89 cm and 19.5 leaves under polyethylene covering material. White net (control) recorded the lowest average values in stem length, diameter, leaf area and number were 14 cm, 0.66 cm, 219.6 cm2 and 15.9 leaves, respectively. Polyethylene covering material led to positive impacts on the vegetative growth and developed of grafted mango seedlings during this season. | ||||
