“…Growth retardants can hasten tuber initiation (Dyson, 1965;Bodlaender and Algra, 1966;Gifford and Moorby, 1967;Humphries and Dyson, 1967;El-Antably et al, 1967;Harris, 1969, 1971) and some of these are considered to prevent gibberellin synthesis or action. The only anomalous result is that of El-Antaby et al (loc.…”

In the past decade there have been several books and reviews which have considered the physiology of potatoes (Ivins and Mil thorpe, 1963;Burton, 1966;Milthorpe and Moorby, 1967;Moorby and Milthorpe, 1975). The first two of these were concerned, in part, with trying to put the study of the potato crop on a firm fundamental basis. The second two reviews reported how this work was proceeding. It seems appropriate for the purposes of this book to describe the present state of our knowledge of potato physiology and, probably more important, to discuss how our attitudes and research priorities have changed and suggest areas where we appear to need further information.Discussions such as this have usually started with the dormant tuber and subsequent development of sprouts during storage. I believe that basic physiology of sprout growth is now well understood and I intend to devote more attention to non-storage growth. The first, and major part of the chapter will be concerned, therefore, with growth in the field and the development of the crop of tubers. Physiological aspects of storage will then be considered and sprout growth discussed in terms of its management for different purposes. Growth in the field Pre-emergence growthThe potato is different from most other major annual crops in that it is usually propagated vegetatively. The seed tuber bears a number of sprouts, some or all of which may be growing. It is these growing sprouts which produce the daughter plant and the subsequent crop and, unless P. M.

“…Growth retardants stimulate tuberisation of potato (Solanum tuberosum) plants under unfavourable environmental conditions (Dyson 1965;Menzel 1980) and chlormequat (2-chloroethyltrimethyl ammonium chloride) is widely used in tissue culture media to promote microtuber formation (Tovar et al 1985;Rosell et al 1987). It induces microtuber formation by a wide range of Solanum genotypes of diverse genetic backgrounds (Estrada et al 1986).…”

The growth retardant chlormequat stimulated microtuber formation by a recalcitrant cultivar of potato (Solanum tuberosum), but reduced microtuber fresh weight in a cultivar that tuberised readily in its absence. Inhibition of microtuber growth by high concentrations of chlormequat was confirmed using a different in vitro system where all cultivars tuberised in the absence of growth retardants.Alternative growth retardants were tested. Daminozide also had a detrimental effect on microtuber fresh weight, but ancymidol and paclobutrazol did not inhibit microtuber growth at the concentrations required for stimulation of tuberisation by recalcitrant cultivars. In addition, 10-SM ancymidol and paclobutrazol inhibited premature sprouting of microtubers in vitro.

“…(i) Since GA3 was found to inhibit tuber formation and CCC is known to antagonize the effects of GA3 in a number of systems (p) it was decided to investigate the effects of CCC on tuberization in S. andigena. Dyson (1965) has reported that CCC retards the growth of shoots and stolons, and causes earlier tuber formation in cultivated varieties of potato which lack an obligate requirement for SD. In the following experiment the effect of CCC on tuberization of S. andigena plants maintained under noninductive LD conditions was studied.…”

SUMMARYThe role of various growth-regulating substances in tuberization in Solanum andigena was studied (i) by application of exogenous growth regulators, and (2) by studying variation in the levels of endogenous hormones under tuber-inducing and non-inducing conditions. In shortday induced cuttings tuberization was inhibited by gibberellic acid; indoie acetic acid and kinetin (6-furfuryl aniino purine) caused slight stimulation of tuber growth at low concentrations, but inhibited it at higher concentrations. Application of (2-chloroethyl) trimethylammonium chloride (CCC) promoted tuberization in plants growing under non-inducing longday conditions and in buds produced on isolated plugs of tuber tissue. The tuber-inducing effects of CCC were not reversed by simultaneous application of GA3. Levels of endogenous gibberellins decreased markedly under short-day conditions, but there was no difference in the levels of endogenous abscisic acid under long and short days. The reduced levels of gibberellins were maintained for at least 2 weeks when induced plants were transferred from short-day to long-day conditions. Application of CCC under conditions which promoted tuherization caused a reduction in gihberellin levels. The role of growth hormones in the regulation of tuberization is discussed.
