Hormonal regulation of tuber formation in potato plants

The endogenous plant hormones and ratios regulate sugar and dry matter accumulation in Jerusalem artichoke in salt-soil

“…Samples were collected at eight stages (July 30th, August 14th, September 2nd, September 17th, October 08th, October 28th, November 15th, and November 28th) from the field experimental base. In our study we divided the tuber formation process into three stages according to Aksenova et al (2012) with some modifications. 1.…”

“…A sufficiently high level of carbohydrate accumulation is essential for tuber formation. For example, potato tuberization is preceded by photosynthesis activation, assimilate accumulation in stalks, and intense transport to underground organs (Aksenova et al, 2012). It is well known that carbohydrate is stored in the form of inulin in Jerusalem artichoke tubers (Denoroy, 1996).…”

Balance between salt stress and endogenous hormones influence dry matter accumulation in Jerusalem artichoke

“…Six replicate plant samples were taken in each plot during tuber development at the following growth stages: seedling stage -July 30; tuber formation -August 30; early stage of tuber expansion -September 30; middle stage of tuber expansion -October 30; and late tuber expansion -November 30 (Aksenova et al, 2012). At each sampling, the whole plant of Jerusalem artichoke was excavated, and youngest fully-expanded leaves and stolons or tubers were washed in deionized water, blotted dry with absorbent paper, wrapped in foil, placed in separate 50-mL centrifuge tubes, and snap-frozen in liquid nitrogen for transport to the lab.…”

Efecto de las hormonas vegetales y el fotoperiodo en la producción de microtubérculos de papa (Solanum tuberosum L.)

“…Estos órganos pueden ser utilizados como semillas certificadas y constituyen una fuente de almacenamiento e intercambio seguro de germoplasma (Donelly et al, 2003;Kämäräinen-Karppinen et al, 2010;Mamun et al, 2015). La micropropagación y la microtuberización proporcionan un modelo experimental uniforme y conveniente para el mejoramiento del cultivo de la papa; sin embargo, el éxito de estas técnicas depende de factores tales como: la temperatura, la consistencia física del medio de cultivo, la concentración de sacarosa, el balance hormonal y el fotoperiodo (Khuri & Moorby, 1995;Rodríguez-Falcón et al, 2006;Sakar, 2010;Aksenova et al, 2011;Dhital & Lim, 2012;Alva & Oropeza, 2013).…”
