YIELD AND YIELD COMPONENTS OF GREENHOUSE, FIELD AND SEED BED GROWN POTATO (Solanum tuberosum L.) PLANTLETS
نویسندگان
چکیده
The aim of the research was to determine field, greenhouse and seed bed performance of plantlets derived from in vitro propagated plantlets of three potato cultivars. Generally, higher values were obtained from the mid-early maturing cultivar Marabel, compare to other cultivars (early cultivar Velox and and mid-early cultivar Concorde) for tuber yield, tuber number and average tuber weight. For these yield components, in the field and seed bed plantlets were found lower values than greenhouse plantlets. The percentage of >4 g tuber weight was obtained for approximately 80 % in greenhouse and field plantlets and between 45 to 55 % in seed bed plantlets. These results indicated that greenhouse and seed bed potato plantlets can be used effectively to expand production of basic minituber seed stocks.

Seedlings of aubergine (Solanum melongena L.) cv. ‘Rima’ were used as scion (R) and control (non-grafted) and rootstock (self-grafted) (RR), while two hybrid tomatoes ‘Heman’ (Lycopersicon hirsutm) and ‘Primavera’ (Lycopersicon esculentum) were used as rootstocks. Grafted and non-grafted plants were grown in the greenhouse and in the open-field. Grafted plants Rima and Heman (RH) were more vigo...

Tuber and root crops virtually exclusively accumulate storage products in the form of carbohydrates. An exception is yellow nutsedge (Cyperus esculentus) in which tubers have the capacity to store starch and triacylglycerols (TAG) in roughly equal amounts. This suggests that a tuber crop can efficiently handle accumulation of energy dense oil. From a nutritional as well as economic aspect, it w...
