Influence of amino acids, bleed grape and seaweed extract on vegetative growth, yield and its quality of fig

Amino acids are considered as precursors and constituents of proteins (Rai, 2002), which are important for stimulation of cell growth. They contain both acid and basic groups and act as buffers, which help to maintain favorable pH value within the plant cell (Cerdana, et al.,2009). Amino acids can directly or indirectly influence the physiological activities in plant growth and development such as exogenous application of amino acids have been reported to modulate the growth, yield and biochemical quality of squashes and garlic plants (Hounsome, et al., 2008 , Abd El-Aal et al., 2010; Shiraishi et al., 2010, ). Amino acids are responsible for improving physical and chemical parameters of fruits as well as increasing the productivity of trees ( Mouco, et al,2009) .The spraying with amino acids led to increased leaf containing from growth regulators cytokinines (Cks) , Gibberellins (GA3 ), Auxins , chemical eliminates and reducing Abscisic acid (ABA) (Talaat, et al,2013). Shehata , et al,(2011) found that spraying strawberry with amino acids and seaweed extract led to increased the length of fruit, diameter of fruit, weight of fruit, fruit firmness, percentage humidity of fruits , total yield .Datir, et al(2012) found that , spraying with amino acids has the positive effect in fruits growth and it is quality . Algae extract as a new bio fertilizer containing N, P, K, Ca, Mg, and S as well as Zn, Fe, Mn, Cu, Mo, and Co, some growth regulators, polyamines and vitamins applied to improve nutritional status, vegetative growth in different orchard such as vineyards ( Elham, et al., 2010 ). Subba Rao (2008) noticed the impact of algae extract application to orchard trees was caused a significant increased total chlorophyll in leaves , total yield of tree , total soluble solids ,vitamin C , and fruit firmness . Al – Hamdawi (2016) found that ,spraying trees of fig cv. Aswod Diala with Hletab and Kelpak led to increased leaf aria and the content of leaves from total chlorophyll , shoot length ,number of shoots , total carbohydrates percentage in shoots , total yield of tree and its quality compared with control treatment . Bondok et al(2013 ) found that spraying grape trees with extract of alga's ( Acadian , Goemar and BM86 ) at conc. of ( 0.5 , 1 and 2 % ) caused increase in the vegetative growth and fruits quality with increase of concentration of extract of alga's. Foliar application of mixture of amino acids and seaweed extract at different growth stages had a positive effect on vegetative growth, reproductive growth, and berry quality of grapevines. Multiple application of 0.5 mL L-1 mixture of amino acids and seaweed extract at flowering + fruit setting + one month after fruit setting stages is quite effective to improve growth and berry physicochemical quality characteristics of ‘Perlette’ grapes (EKhan, et al., 2012 ) .The purpose is to study the effect of spraying with amino acids(Amister and Gusto) , Bleed of grape and seaweed Ascophyllum nodosum treatments and their interactions on vegetative growth , yield and fruit quality of local fig tree cv. Aswod Diala .
