Potato development from a seed or tuber is a complex process involving asexual reproduction through tuber propagation and sexual reproduction through flower pollination. The root provides nutrients and water for stolon and tuber growth (Iwama2008). Drought substantially affects yield, especially in shallow...
The method comprises culturing of sanitated potato plants in vitro by grafting on a nutrient medium containing macro- and microelements according to Murashige-Skoog, sucrose, Fe-chelate, glycerol, indole acetic acid, agar-agar, vitamins according to White, obtaining meristematic regenerated plants and...
tubers is not certainly known, but Professor Bernard has suggested that it is the presence of a fungus, Fusarium solani, which, growing in the underground shoots, irritates them and causes the swelling; the result is that an efficient method of propagation is secured independently of the seed....
One substantial disadvantage of vegetative propagation though is that diseases are easily transmitted across clonal generations during propagation; another is that potato planting material is bulky and perishable by nature and the production of healthy material is expensive. The single most challenging ...
Engrafting transmits all known viruses. This way of transmission is important in orcharding where plants are reproduced by engrafting on stocks. Engrafting transmits such destructive diseases as apple-tree mosaic, peach rosette, orhopcurly top. ...
Survival and propagation of phytopathogenic viruses Survival. Viruses cannot reproduce and most of them cannot survive for a long time outside living plant cells. The best source of their survival in winter is vegetative parts of infested plants. Therefore, viruses inflict the greatest loss to the...
in Sweetpotato virus and propagation systems mainly in African countries. The main virus diseases are described as well as selection and breeding efforts, both by conventional and genetic engineering approaches. Operations of pilot plants supplying farmers with virus tested planting material were suggested...
In order to improve the detection technologies of the viruses in test-tube plantlets of sweet potato, we have been rapid propagation the test-tube plantlets ofIpomoea setosain the medium MS+IBA 0.2 mg/L using the growing point on the stem ofIpomoea setosathat sprouting by the seeds in the...
Effects of pre-elite seed size and planting density on development and propagation efficiency of two virus-free potato cultivars in Sichuan Province, China The aim of the experiment is to develop a high-output and low-cost method for propagating elite potato seed in the field from pre-elite ...
Figure 1.The tuber photographs of six potato clones used for reciprocal grafting. (A) A red potato clone ‘21-1’ with red skin and red flesh. (B) A white potato clone ‘21-3′ with pale yellow skin and white flesh. (C) A purple potato clone ‘1417-5′ with purple skin and purp...
