To convert a haploid organism or cell into a diploid state by doubling the chromosome set.
From 'diploid' + '-ize' (to make or become). This verb emerged in genetic engineering and breeding science as scientists learned to manipulate chromosome numbers.
Scientists can actually take a plant cell with one set of chromosomes and diploidize it by doubling all the chromosomes—suddenly a small, weak plant becomes big and strong, which is why many crop plants are artificially diploidized.
