The Effect of Variety and Gibberellic acid and Brassinolide and their Interaction on Some of The Chemical Characteristics and Total chlorophyll of the plant Dill Anethum graveolens L.

The experiment was carried out to study the effect of variety and gibberellic acid in concentration (0 and 50)mg.lat-1 and BL in five concentration (0, 0.50 ,1 ,2 and 3)mg.ltr-1 and their interaction in some chemical Characteristics and total chlorophyll for Dill plant . the experiment designed according Randomized Complete Block Design (RCBD) and three replicates per treatment, compared to the average using less significant difference at the level of probability (0.05) , the results showed the following:- The effect of brassinolide with it,s concentrations led to obtain a significant increase in all the studied characteristics, so the superiority of the concentration of 2 mg.L-1 of brassinolide in each of Ca, Mg,Fe, and total chlorophyll The effect of gibberellic acid with it,s two concentrations led to obtain a significant increase in all the studied characteristics and the highest in of the concentrate at 50 mg.L-1in two local and hol and varieties. The all bilateral interactions had a significant effect on all the studies characteristics with superiority of the treatment (2 from brassinolide, 50 from gibberellic acid) mg. L-1 in the ratio of Ca, Mg,Fe and total chlorophyll. The tripleinter actions led not to obtain a significant increase in all of the study of significant factors

Analysis nonlinear deflection based on the elastica theory with solving elliptic integrals and method of iterations. For external load ( P ) is small ( P < 0.70 unit ) deflection less significant difference ( å < 5 % ) . For external load ( P ) increasing ( P > 0.70 unit ) , the difference is increasing the amount of deflection in significant. Deflection obtained by using the theory elastica smaller than the deflection by linear theory .Keywords : Nonlinear deflection , elastica theory , elliptic integrals , method of iterations , MAPLEAbstrakDalam kajian ini penulis menganalisis lendutan nonlinier pada tumpuan jepit bebas dengan beban titik P di ujung. Analisis lendutan nonlinier berdasarkan teori elastika dengan pemecahan integral elliptik dan metode iterasi. Untuk beban luar (P) yang kecil (P < 0.70 satuan) perbedaan lendutan kurang signifikan (å < 5%). Untuk beban luar (P) yang semakin meningkat (P > 0.70 satuan) maka perbedaan besaran lendutan semakin meningkat secara signifikan. Lendutan yang diperoleh dengan menggunakan teori elastika/nonlinier lebih kecil dibandingkan lendutan dengan berdasarkan pendekatan teori linier.Kata kunci: Lendutan Nonlinier, Teori Elastika, Integral elliptic,Metode Iterasi, MAPLE.
