Host plant resistance is an important component to the management of potato late blight, Phytophthora infestans (Mont.) de Bary. Assessment of potato lines (Solarium tuberosum L.) with various levels of resistance to P. infestans (US8, A2 genotype) were evaluated in field trials, greenhouse controlled environment chambers and inoculated tuber reactions. Five lines (AWN86514-2, B0692-4, B0718-3,...
Volunteer Potato (Solanum tuberosum) Control with Herbicides and Cultivation in Onion (Allium cepa)1
Volunteer potatoes are difficult to control in onions and can greatly reduce onion growth and yield. Herbicides and cultivation were evaluated for control of simulated volunteer potatoes in onions in 1996 and 2000. Three interrow cultivations did not control potatoes in the onion row and the remaining plants reduced onion yield 50 and 73% compared with the hand-weeded checks. Three applications...
The potential of tuber flour of Ipomoea batatas (L.) Lam. cv. Brazlândia Branca (white sweet potato) as wound healing and antiulcerogenic agent was investigated in vivo in animal model. Excision on the back of Wistar rats was performed to induce wounds that were topically treated with Beeler's base containing tuber flour of white sweet potato at 2.5%. Number of cells undergoing metaphase and th...
Potato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infection by the tuber necrotic strain of Potato virus Y (PVYNTN). PTNRD negatively impacts tuber quality and marketability, and poses a serious threat to seed and commercial potato production worldwide. PVYNTN symptoms differ in the cultivars Waneta and Pike: Waneta expresses severe PTNRD and foliar mosaic with...
21 century. Such an increase in the atmospheric CO may effect plant growth and productivity of crop plants. st 2 A field experiment was conducted with two potato cultivars namely Kufri Surya and Kufri Chipsona-3 grown inside Open Top Chambers (OTCs) at ambient (385±30 μmol mol ) and elevated CO (570±50 μmol mol ), 1 1 2 during rabi season of the year 2009-2010. The experiment was planned in a r...
Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affectinulin content and inulin yield of Jerusalem artichoke. However, there is limited information ongenotypic response to seasons for inulin content and inulin yield. The objective of this studywas to investigate the variability in genotypic response to seasons for inulin content and inulinyield of Jerusalem a...
The effects of light and quantity of spawn on the sporophore and sclerotial yields of Pleurotus tuber-regium, cultivated on cotton wastes, rice straw, cocoyam peel, comcob, groundnut shell and sawdusts of Mansonia altissima, Khaya ivorensis and Boscia angustifolia were observed. The organism had sporophore and sclerotial yield values of 36.8 and 27.6 g kg(-1) waste, respectively, in cotton wast...
At harvest, potato (Solanum tuberosum L.) tubers are in a dormant state and do not have the ability to sprout. After harvesting, tuber dormancy is released progressively. This release is accompanied by numerous physiological and biochemical changes, such as carbohydrate hydrolysis and the accumulation of saccharides, which are detrimental to the nutritional and processing qualities of potatoes....
BACKGROUND AND AIMS The control of dormancy in yam (Disocorea spp.) tubers is poorly understood and attempts to shorten the long dormant period (i.e. cause tubers to sprout or germinate much earlier) have been unsuccessful. The aim of this study was to identify and define the phases of dormancy in Dioscorea rotundata tubers, and to produce a framework within which dormancy can be more effective...
AIM The tuber of Amorphophallus paeoniifolius (Family-Araceae), commonly called suran or jimikand, has medicinal and food value. It is used in ethnomedicinal practices for correction of gastrointestinal disturbances such as constipation and hemorrhoids. The present study evaluated the effect of A. paeoniifolius tuber on gastrointestinal motor functions. MATERIALS AND METHODS The tuber was col...
