Document Summary

Dwarfing: selected rootstocks and grafted to apple trees for different sizes and characteristics. Layering: take branch and burry it in soil, cut a ring in bark to disrupt it but it can still grow. Suckers: grow roots and send suckers up to grow a plant. Tissue culture: artificial growth in a dish to reduce regeneration to help make more plants. Culture media contains: minerals, vitamins, carbohydrates, gelling agent, plant growth regulators. Transgenics: take a foreig(cid:374) ge(cid:374)e, i(cid:374)sert i(cid:374) pla(cid:374)t (cid:272)ell a(cid:374)d rege(cid:374)erate a (cid:272)o(cid:373)plete pla(cid:374)t, if pla(cid:374)ts are(cid:374)"t developed then that"s a big challenge. Virus eradication: can create a plant that is virus free from an infected plant because the meristem is not connected to the vascular system. Micronutrients are little required nutrients and macronutrients are nutrients that are devoutly needed. Cultivars are heterozygous: all the plants in the field are the same genotype but they are heterozygous (hybrid vigour)
