“…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.

“…Hammes and Nel (1975) postulated that a balance between endogenous gibberellins (GA) and a tuber forming-stimulus control tuber formation; for tuberization to occur the GA level must be below the threshold level. This balance can be altered by GA biosynthesis inhibitors such as 2-chloroethyl trimethyl ammonim chloride (CCC) (Menzel 1980) and B-995 (Bodlaender and Algra 1966).…”

Two similar field trials were carried out during 2003 in a hot tropical region of eastern Ethiopia to investigate the effect of leaf and soil applied paclobutrazol on the growth, dry matter production and assimilate partitioning in potato. A month after planting paclobutrazol was applied as a foliar spray or soil drench at rates of 0, 2, 3, and 4 kg a.i. paclobutrazol ha À1 . Plants were sampled during treatment application and subsequently 2, 4, 6 and 8 weeks after treatment application. The data was analyzed using standard growth analyses techniques. None of the growth parameters studied was affected by the method of paclobutrazol application. Paclobutrazol decreased leaf area index, crop growth rate, and total biomass production, and increased specific leaf weight, tuber growth rate, net assimilation rate, and partitioning coefficient of potato. At all harvesting stages, paclobutrazol reduced the partitioning of assimilate to the leaves, stems, and roots and stolons and increased allocation to the tubers. Although paclobutrazol decreased the total biomass production it improved tuber yield by partitioning more assimilates to the tubers. Paclobutrazol improved the productivity of potato under tropical conditions by redirecting assimilate allocation to the tubers.

This balance can be altered by the application of GA biosynthesis inhibitors such as 2-chloroethyl trimethyl ammonium chloride (CCC) (Menzel 1980) and B-995 (Bodlaender & Algra 1966). Recently, the in vivo and in vitro responses of potato to paclobutrazol (PBZ) have been reported (Balamani & Poovaiah 1985;Langille & Helper 1992;Simko 1994;Bandara & Tanino 1995).…”
