Plant roots exudates influenced root-knot nematodes egg hatch, as root exudates of resistance tomato cultivars were known to produce higher amount of compounds associated with resistance, which included heptadecane, tridecane, tetradecane, hexadecane, pentadecane, hexatriacontane, hexadecane, 2,6,10,14-tetramethyl, octadecane, nonadecane, eicosane and heneicosane against Meloidogyne incognita(Yang et.
The PCM tests show that the technical grade n-tetradecane maintains a sharp freeze point temperature, but that the freeze point is depressed from 5.6[degrees]C (42.1[degrees]F) for pure tetradecane to ~ 4[degrees]C (~39.2[degrees]F) for our technical grade product.
Of the three hydrocarbons, in nymphs poor positive attraction (+0.02) was observed for tetradecane on the contrary overall repellency was found (Table 5).
Among them the liquid alkanes (undecane dodecane tridecane tetradecane pentadecane hexadecane heptadecane etc.) are widely used in fuel oils and as anti-corrosive agents in lubricating oils and solid alkanes (octadecane nonadecane eicosane heneicosane tricosane tetracosane heptacosane octacosane etc.) find their use in paraffin waxes of different kinds.
The peak areas of all the components with retention times less than that of tetradecane or diethyl adipate are integrated to determine the amount of VOC content.
Tetradecane is chosen due to its freezing point being suitable for chilled water storage systems (~ 5.6[degrees]C, ~42[degrees]F), high heat of fusion (~200kJ/kg, ~86 BTU/[lb.sub.m]), and the lack of a subcooling requirement for freezing.
The chromatogram also showed the presence of other minor compounds such as octadecane (0.29%), naphthalene (0.13%), tetradecane (0.41%), pentadecane (0.58%), hexadecane (1.02%), heptadecane (0.53%), and cholesterol (5.07%) (Table 2).
An organic phase was dissolved in hexane/ethyl acetate (proportion of 1:1) which contained tetradecane as internal standard, and the injection was carried out into the GC (FREITAS et al., 2009).
The [V.sup.E.sub.m] curve for the mixture of noctane and octan-2-ol is sigmoidal and tends to change to positive values at higher mole fractions ([x.sub.1] [greater than or equal to] 0.65) of noctane while [V.sup.E.sub.m] values for n-decane, n-dodecane, and n tetradecane with octan-2-ol mixtures showpositive deviation over the entire composition range.
Common secondary metabolites present in leaf tissue and leaf calluses were toluene, a-sphinosterol, quercetin, tetradecane, pentadecane, hexadecane, octadecane, hentriactone and 9,12-octadecadienoicacid[7,7] (Table II).
leucocephala and P africana includes; tetradecane, hexadecane and heptadecane.
Among secondary metabolites determined, the common secondary metabolites present in leaf and internode tissue were Toluene, a-sphinosterol, Tetradecane, Pentadecane, Hexadecane, Octadecane, Hentriactone, and 9,12-Octadecadienoicacid[7,7].
A spectrometric analysis shows that this product is a mixture of five paraffins: tetradecane (33%), pentadecane (43%), hexadecane (17%), heptadecane (5%) and octadecane (2%).
