Propagation of phytosanitary clones by in vitro culture
Scientific and Practical Institute of Horticulture, Viticulture and Food Technologies, Kishinev, Moldova
This article presents the process of accelerated reproduction of healthy clones of grapes, including the following stages: growing young shoots of the original plants of clones, introducing tops into in vitro culture, microclonal cuttings, adaptation of microplants to ex vitro culture, transplanting into cassettes with a soil substrate, transferring plants to a greenhouse for growing to the condition of vegetative seedlings and planting in a pre-propagation mother stock. For the successful implementation of each of the above operations in the SPIHVFT, a Cultural Complex has been equipped, consisting of a number of interconnected premises: a sterile box, a culture chamber and a vegetation chamber. The use of this Complex allows multiplying the required number of plants during the year, to grow vegetative seedlings by the spring of the next year and plant them in the pre-propagation “Pre-base” mother plant. After a year, grafted vegetative seedlings grown from the vines of the mother plant were used for laying the mother stock.
