Salinity is widespread environmental stress that poses great obstacles to rapeseed development and growth. Polyamines are key plant growth regulators play a pivotal role in regulating salt tolerance. Rapeseed (Brassica napus L.) seedlings were treated by spermine (Spm) spermidine (Spd) versus untreated control under conditions. It was detected the Spd-treated plants had significantly elevated chlorophyll proline content maintained higher photosystem II (PSII) activity than those with Spm as...
Determining the appropriate parents for breeding programs is most important decision that plant breeders must make to maximize genetic variability and produce excellent recombinant genotypes. Several methods are used identify genotypes with desirable phenotypic features experiments.
