Inquiry of inclined magnetic field effects on Walter –B nanofluid flow with heat generation / absorption

The article deals with Walter-B nanoliquid flow towards a extending surface with inclined magnetic field effects. Thermal relaxation analysis is made by non fourier heat flux model. Radiation, heat generation / absorption impacts are included. The non linear Partial governing systems are rebuild into nonlinear ordinary systems with the assist of proper similarity transformations. The graphical results are portrayed for velocity, concentration and temperature profile. The physical entitles of heat and mass transfer rates are graphically reported. The comparission with previous results notified the excellent agreement

Phenylalanine ammonia lyaseand total phenol content in resistant banana to Pratylenchus coffeae

The biochemical alterations in resistance banana accessions showed that relatively higher Phenylalanine Ammonia Lyase (PAL) activity than the susceptible ones indicating the inherent higher content of PAL in resistant accessions. The higher activity of this enzyme in resistant accessions viz., Karthobiumtham, M. balbisiana, Kanai Bansi, Bhimkol, Athiakol, Aittakol, Kechulepa was negatively correlated with lesion index of roots and corm. Increase in phenol content and enzyme activities were negatively related with the degree of infestation. In the present study, total phenol estimated in roots of banana genotypes showed that these compounds were higher in resistant accessions than susceptible ones

Mechanism of resistance in banana cultivars against root- lesion nematode, Pratylenchus coffeae

Ten diploids and forty-nine triploids comprising of wild and cultivated banana accessions collected from different parts of India were screened under pot culture for understanding the mechanism of resistance against root lesion nematode, Pratylenchus coffeae. Following inoculation of banana plantlets with the nematodes, the peroxidase activity increased in both the resistant and susceptible genotypes. However, the final enzyme concentration was the maximum in resistant diploid accessions like M. balbisiana, Kanai Bansi, Aittakola, Bhimkol and Athiakol. A critical analysis of the polyphenol oxidase activity in this study revealed that resistant accessions viz., Kechulepa, M. balbisiana, Karthobiumtham, Kachkel, Bhimkol, Athiakol, Kanai Bansi and Aittakola recorded higher polyphenol oxidase activity than the susceptible ones
