error term ɛ is assumed to have normal distribution with constant variance. The model parameters are represented by θ (instead of by β used for linear models) to highlight that these models are nonlinear ( Bates and Watts, 2007 ). Results Distillation

Texas where R. multiflora was used as a rootstock for garden rose production ( Ong et al., 2015 ; Philley, 1995 ). By 1994, RRD distribution was as far east as Tennessee, Ohio, Pennsylvania, and West Virginia ( Amrine, 2002 ) with reports mainly

genetic pathways that underlie these phase transitions will lead to a better understanding of what drives plant diversification and distribution in relation to ecological factors. Another important question is how the timing of vegetative phase change is

. Atchley et al. (1976) suggested that ratios greatly confuse and, in many cases, invalidate critical statistical or biologic analyses of the original data. Packard and Boardman (1988) suggested that ecologic physiologists discontinue using ratios to

western United States and Canada often have serious horticultural impacts (see Quamme et al., 2009 ). Topographic effects on the spatial distribution of the PH statistic are complex, due to competing effects of cooling with elevation and cold-air pooling

), caused by R. solanacearum , can be very problematic for all tomato growers as a result of lack of available resistance genes within cultivated tomato ( Opena et al., 1990 ; Walter, 1967 ; Wang et al., 1998 ) and widespread distribution in the southeast
