Studies On The Effect Of X-Ray On The Growth And Yield Of Okra (Abelmdschus Esculentus (L) Moench):- Ochor, Goodluck .A.

ABSTRACT

 This investigation was carried out to detennine the Effective Dose (ED) and effect of X-ray doses on percentage gennination, growth and yield components of seedlings derived from okra (Abelmoschus esculentus (L). Moench) varieties (Yakasa and Clemson spineless).Seeds of the two okra varieties were treated with (1, 2,4, 6, 8 MGy) at the Federal Medical Centre (FMC) Xray Unit.The treated seeds were sown in nylon bags in a green house for two weeks. Data collected was subjected to simple linear regression analysis to establish the effective dose. Two dose were chosen from each of the varieties for the field experiment. The experiment was designed in a 2X3 in Randomized Complete Block Design (RCBD) with three replicates. Germination percentage was collected and subjected to statistical analysis. The result obtained on gennination percentage was not significantly different on the two okra varieties under study. The effect of the different X-ray doses on the growth parameters and yields differed. The lower radiation dose (2 MGy) was more effective in Clemson spineless whereas the highest dose (6 MGy) had more significant impact in Yakasa than the lowest (4 MGy). In general, irradiating seeds of Yakasa with X-ray dose of 6 MGy before sowing is therefore recommended this also applies to Clemson spineless at a dose of2 MGy.
