The dramatic changes in oxygen consumption which occur following slicing of dormant tuber tissue have been well documented (6, 7, 9). It has been difficult to interpret the results of various workers because the investigators have frequently employed different methods of slicing, aeration, and illumination, as well as various culture solutions, temperatures, and types of tissue. Lee and Chasson...

Micropropagation and minituber production technology may enable the establishment of potato (Solanum tuberosum L.) seed tuber certification programs in arid and semiarid regions of the world and reduce dependency on expensive seed tuber imports. Therefore, we investigated possible carry-over effects of moderate salt stress on the following production cycle. The yields of seed tuberand microtube...

Steroidal glycoalkaloids (SGAs) existing in most potato tissues are toxic to humans when the fresh weight is over 200 mg kg?1, and high SGAs content would also damage quality of tubers. Sterol side chain reductase 2 (StSSR2) a key enzyme biosynthetic potatoes. To reduce concentration tetraploid cultivated (Solanum tuberosum L.), gene StSSR2 was edited by CRISPR/Cas9 system. A total number 64 mu...

Abstract Auxin is known to be involved in various developmental processes, including meristem identity, shoot branching and initiation of potato tubers. The previously identified StYUCCA8 gene that exhibits a peak expression after tuber induction prior swelling was cloned over-expressed order study the effects altered auxin content on stolon architecture development. plants transformed with 35S...

to study the effect of seed density and plant distance on yield and growth parameters of radish, an experiment was conducted in research of station rice at office rasht in 2008-2009. this study was set in secondary culture after rice by factorial experiment with randomized complete block design with 3 replications. treatments consisted of factorial arrangement of three seed density levels (5, 1...

Objective: An experiment was performed in Ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. Agria. Methods: This research was conducted in factorial design based on randomized completely blocks design in three replication  in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...

Canna indicaL.roots are used for medicinal purpose. A decoction of the root with fermented rice is used in the treatment of gonorrhea and amenorrhea. The seed of canna is extremely hard, and needs to be "scarified" before sowing. The aim of the present investigation is to determine the hardiness problem of the seed. The seed sample was collected from the IARI, New Delhi in 2008. The wo...

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...

A soluble viscous protein was purified from yam (Dioscorea opposita Thunb.) tuber mucilage tororo by chromatographic steps, and its functional properties were estimated. The purified dioscorin having the molecular weight of about 200 kDa exhibited high scavenging activities against hydroxyl radicals (IC50 = 195.1 microg/ml) and superoxide anion radicals (IC50 = 92.7 microg/ml). Moreover, it sho...

Potatoes represent an important staple food crop across the planet. Yet, to maintain tuber quality and extend availability, there is a necessity to store tubers for long periods often using industrial-scale facilities. In this context, preserving potato quality is pivotal for the seed, fresh and processing sectors. The industry has always innovated and invested in improved post-harvest storage....
