I read some papers about nanowire synthesis, the seed layer (ZnO, Ag...) can be directly by taking some method onto plastic. I want to know should not the suitable lattice parameter of substrate is important to growth of nanowire or nanorod? I want to know what will happen if I use spin coating to let ZnO seed layer directly onto the plastic substrate？
I think 1D growth requires confinement in other two dimensions...now how to achieve that...1. Either material crystal has one plan growth favouring...or 2. Substrate creates condition along with nature to make this possible...you can see many paper as proof of role in growth mechanism.

Yes, in order to grow a 1D nanostructure, the seed layer is one of the major requirements, but the substrate also plays a crucial role in the growth plane of the nanostructure.
Please find the attached document which will surely help your concern.
The structural and optical properties of ZnO nanorods are investigated as a function of growth temperature of the seed layer. The seed layer comprising of ZnO nanocrystallites is grown on ITO substrates at five different temperatures (150–550 °C) and the nanorods are grown on the seed layer by the facile hydrothermal method. The seed layer grown at 350 °C is observed to be uniformly textured with c-axis orientation leading to the synthesis of vertically aligned nanorods with smaller diameter. The HR-TEM analysis and the intense peak along (002) direction in the XRD spectra of this sample implied that the nanorods possess c-axis orientation. An enhanced UV emission is also observed in the photoluminescence spectra of this sample. The diversity in the morphology and orientation of the seeds at different temperatures has been explained by the growth kinetics of the ZnO nanocrystallites.
