“…Leaf area at the end of the transplant production phase was larger for transplants raised at higher than at lower temperature (Table 3), and so was the initial aboveground leaf area in the subsequent tuber production phase (Table 4). This agrees with results from Tadesse et al (2001). No significant effects of temperature during transplant production on leaf area were present anymore at the end of the tuber production phase (Table 4).…”

“…However, individual plants pre-cultured at higher temperature (Table 4) had higher fitted A-values and a smaller fitted increment in leaf area (C), which agrees with the tendency of a less strong increase in leaf area for transplants raised at higher temperature (Figure 6). These results, however, were not consistent with a higher light interception found for field crops from transplants grown at a higher temperature (Tadesse et al, 2001). A higher temperature during transplant production also resulted in higher leaf numbers at the end of the transplant production and at the beginning of the tuber production phases.…”

Aboveground leaf area and leaf number development of in vitro produced potato plantlets was studied over three growth phases. In vitro plantlets were produced at 17 or 23°C (normalisation phase, 3 weeks), planted in soil at 18/12 or 26/20°C (transplant production phase, 2 weeks), and later transplanted at 18/12 or 26120°C (tuber production phase, 6 weeks).Boosts in leaf area increase and leaf appearance occurred in the first days after planting to soil. A shock in leaf area increase occurred after the later transplanting. Both for plant averages and most individual plants, leaf area increase in all growth phases was best described by logistic curves, indicating growth limitations occurred in all phases. These limitations were least severe during the relatively short transplant production phase. Higher temperatures did not significantly increase leaf area during normalisation, increased leaf area during transplant production, and first increased but later reduced leaf area during tuber production. Higher temperatures increased leaf number in all phases. After-effects of normalisation temperature occurred during transplant production but no longer during tuber production. Aftereffects of transplant production temperature occurred during tuber production. After-effects were direct (affecting plants at the beginning of the next phase) or appeared later.

“…In order to have any effect, conditions during transplant production therefore must be changed to non‐inducing for more than 11 days up to 18 days (3 weeks minus 3 days of hardening). This probably explains why Tadesse et al (2001 b ), studying the effect of temperature during production of transplants grown for 2 weeks (with 12 days of different conditions), mainly found effects on leaf area and radiation interception of the crops but only limited effects on the degree of dry matter partitioning to tubers.…”

In transplants from in vitro-derived plantlets from very early potato (Solanum tuberosum) cultivars, a lower degree of tuber induction at the time of field planting is thought to increase tuber production. Leaf-bud cuttings were used to assess the progress to tuber induction in in vitro-derived potato plantlets during the transplant production phase and after subsequent transplanting into the field. Induction and initiation of tubers on the same plants were assessed to study the effects of the duration of transplant production and conditions during transplant production for cv. Gloria (very early) and cv. Bintje (mid-early). In vitro-produced plantlets were not induced by the time of planting but rapidly progressed to the induced state thereafter. The progress in induction with time and the change in percentage of plants showing tubers fitted typical sigmoid curves. Plantlets achieved 50% induction ca 15 days after planting into in vivo conditions, and 50% tuber initiation usually occurred 10 days later. Shorter transplant production periods reduced the degree of induction of the transplants at field planting. Transplant production for more than 2 weeks was required to allow conditions during that period to affect induction or initiation. Long-term non-inducing conditions delayed the progress to tuber induction in cv. Gloria and delayed tuber initiation in both cultivars. Cv. Gloria showed no faster progress to induction than cv. Bintje but initiated tubers earlier. The results suggest that the relation between progress to induction and tuber initiation is cultivar dependent and that leaf-bud cuttings can be used successfully in very young in vitro-derived plants for assessing the progress to tuber induction.

“…It has been known that various environmental and endogenous factors influence tuberization . A large number of studies have shown that short photoperiod, high light intensity, low temperature, low nitrogen levels and high sucrose levels can promote tuberization (Dobránzki et al 1999, Tadesse et al 2001, EL-Sawy et al 2007, Dobránszki and Tábori 2010. Phytohormones also play a crucial role in regulating the morphological events of tuberization (Aksenova et al 2012, Roumeliotis et al 2012.…”

Among the multiple environmental signals and hormonal factors regulating potato tuberization, gibberellins (GAs) are important components of the signaling pathways in these processes. To understand the GAs-signaling response mechanism of potato tuberization, a comparative proteomics approach was applied to analyze proteome change of potato tuberization in vitro subjected to a range of exogenous GA treatments (0, 0.01, 0.1 and 1.0 μM) using two-dimensional gel electrophoresis. Quantitative image analyses showed that a total of 37 protein spots have their abundance significantly altered more than 2-fold. Among these proteins, 13 proteins were up-regulated, 13 proteins were down-regulated, one protein was absent and 10 proteins were induced after treatment by exogenous GA . The MALDI-TOF/TOF MS analyses led to the identification of differentially abundant proteins that are mainly involved in bioenergy and metabolism, storage, signaling, cell defense and rescue, transcription, chaperones, transport. Furthermore, the comparative analysis of GA -responsive proteome allowed for general elucidation of underlying molecular mechanisms of potato tuberization inhibited by exogenous GA . Most of these cellular processes were not conducive to the transition from stolon elongation to tuber formation, including a blockage of starch and storage protein accumulation, the accelerated carbohydrate catabolism, a blockage of JA biosynthesis but an elevated endogenous GAs level, the amplification of GA signal transduction by other signaling pathways, and the regulation of cellular RNA metabolism for controlling tuberization. Our results firstly integrated physiology and proteome data to provide new insights into GA -signaling response mechanisms of potato tuberization in vitro.
