The effect of certain exogenous growth regulators on quality of grafted grapevine rootlings
(Springer, Dordrecht, 2005)
Paclobutrazol (PB), chlormequat (CM), fenarimol (FM), and gibberellin A(3) (GA(3)) were applied as exogenous growth regulators once (1 x PB, 1 x CM, 1 x FM, 1 x GA(3)), twice (2 x PB, 2 x CM, 2 x FM, 2 x GA3) or three times ...
Genital organ anomalies in Xiphinema dentatum (Nematoda : Longidoridae)
(Brill Academic Publishers, Leiden, 2005)
Seven specimens of Xiphinema dentatum with abnormal genital organs were found in the same population. Normal females are amphidelphic with the vulva located slightly anterior to the mid-body. Of some 24 000 females examined, ...
