Other treatments have similar effects to those of early planting and include priming of true seed, presprouting of tubers as in potatoes and the use of transplants. Generally, there is some flexibility in the use of such treatments in annual crops but it may be limited by local agro-meteorological conditions or the need to deliver a crop to the market at a predetermined time. Of course, the limitations are even greater in perennial crops.

Potatoes are usually grown from seed potatoes (tubers) or "buds (tiny tissue-cultured tubers), but a few cultivars, such as Explorer and Homestead Hybrid , are grown from true seeds. Prevent problems by planting only certified disease-free tubers. Planting true seeds or buds also helps avoid many tuber-borne diseases. 

Plant oleate desaturase is a membrane—bound enzyme system present In the reticulum of developing seeds, aged storage tissues or growing leaves Most evidence suggests that oleoyl-phosphatldylchollne Is the true substrate of oleate-desaturase. Before subsequent desaturation oleoyl residues are Inserted Into phosphatidylcholine molecules either by an acyl-exchange mechanism between oleoyl-CoA and phospholipids or by acylation to lysophosphatldylchollne HPLC allowed us to follow the time-course of oleate acylation and desaturation In the various molecular species of phosphatidylcholine from potato mlcrosomes. ...
