| Abstract | ||
| This experiment was conducted in a private field in Al – Tohmazia village in Hilla – Babylon Provence during growing seasons of 2014-2015 to find out the influence of Mycorrhiza fungie (M ) (Glumus mosseae) in two levels ( 0 and 50 gm/tree ) , Spraying Putrescine ( P) ( 0, 200,300 ppm, and their interactions in growth and yield of 15 – years old local orange trees Factorial experiment in RCBD doign with three replicates was used in this study . Means were compared using LSD under 0.05 probability . Results can be summarized as follow : Inclusion Mycorrhiza in treatments (M1 ) had a posative impact on all the vegetative trails under this study which resulted in higher means of leaf area , leaf chlorophyll content , leaf content of N . fruit weight , fruit size as well as fungie spores number in soil which gave (40.50cm2, 77.90 SPAD , 2.483 % 145.24 cm3 , 122.39 gm, 40.70 spore ) respectively, with significant different with control treatment (M0) which gave (26.41cm2, 60.12 SPAD, 2.013 %, 120.14 cm3, 113.71gm, 11.52 spore) respectively . Results indicated that the plant hormones treatments Putrescine at ( P2) was superior in most of the study fruits as leaf area , leaf chlorophyll content, leaf content of N , fruit size as well fungie spores number in soil which gave ( 38.28cm2 , 76.63 SPAD, 2.35% , 141.82cm3 ,32.17 spore) respectively compare to control treatment ( P0) which gave 25.77 cm2 , 61.29 SPAD , 2.101 % 121.00 cm3, 16.44 spore ) respectively . Treatment (P1) gave the highest rate of (fruit weight) which gave 120.43 gm compare with control treatment ( P0 ) which gave (114.11gm) .The interactions treatments between Mycorrhizae and Putrescine M1P1 gave significant effect in average leaf area and leaf nitrogen contain which equal to ( 46.29cm2 , 2.576% ) respectively compare with control treatment ( M0P0) which gave (20.75cm2, 1.876% ) respectively . M1P2 treatment cause increase in leaf chlorophyll contain , fruit weight , fruit size as well as spores fungie number which gave ( 83.51 unit SPAD , 152.95cm3, 123.92gm,50.33 spore ) compare with control treatment M0P0 which gave ( 49.93 unit SPAD , 106.61 cm3, 108.62 gm , 7.22 spore ) respectively . | ||
