“…Starch decreased just before harvest in 2-year-old bark and wood and spurs of bearing trees, but to a lesser extent, or not at all, in nonbearing trees. In apple spurs from nonbearing trees, starch was significantly higher than in those from bearing trees during the summer months for 3 consecutive years (Grochowska, 1973). In mandarin, starch levels in leaves, branches, trunk, and roots were at least twice as high in nonbearing than bearing trees.…”

“…For some deciduous fruit tree and vine crops, seasonal changes in nonstructural carbohydrates have been extensively characterized, especially in apple (Beattie, 1948;Chong, 1971;Chong andTaper, 1971a, 1971b;Grochowska, 1973;Hansen, 1967;Hansen and Grauslund, 1973;Hooker, 1920;Kandiah, 1979Kandiah, , 1979bLoescher et al, 1982;Mochizuki and Hanada, 1956;Murneek, 1933;Priestley, 1960Priestley, , 1964Priestley, , 1981Proebsting, 1925;Rao and Berry, 1940;Taper and Liu, 1969;Traub, 1927;Whetter and Taper, 1963) and in grape (Bains et al, 1981;Eifert and Eifert, 1963;Kliewer, 1965;Kliewer, 1967;Kliewer and Nassar, 1966;Marutyan, 1962;Pickett and Cowart, 1941;Scholefield et al, 1978;Winkler, 1929;Winkler and Williams, 1938;Winkler and Williams, 1945).

“…Starch levels in bark, wood, spurs, roots and trunk were higher in non-bearing than in bearing prune trees throughout the year, except at the time of the first growth flush (Davis 1931). Starch in apple spurs from non-bearing trees was significantly higher than in those from bearing trees during the summer months for 3 consecutive years (Grochowska 1973). These and sitnilar reports (Crane and Al-Shalan 1977, Hooker 1920, Lenz and Kuntzel 1974, Ryugo et al 1977 indicate that the presence of reproductive sinks depresses the amount of non-structural carbohydrates stored in vegetative tissues.…”

The effect of fruiting on carbon fixation and retention in leaves was monitored by measuring net photosynthesis (Pn) and total non‐structural carbohydrates (TNC) on a seasonal basis on mature fruiting and non‐fruiting sweet cherry trees (Prunus avium L. cv. Bing). Pn was also measured diurnally during stages II and III of fruit development. Pn rates increased to between 18 and 20 mg CO2 dm‐2 h‐1 during stage II of fruit development and were maintained until harvest. Diurnally, Pn increased in the morning to 20 mg CO2 dm‐2 h‐1 and this rate continued until sunset. Leaf carbohydrate levels decreased in both fruiting and non‐fruiting trees beginning at the equivalent of stage II of fruit growth. Carbohydrates were lower in leaves and woody portions of current, 1‐ and 2‐year‐old shoots of fruiting trees. Although differences were found in levels of non‐structural carbohydrates, no differences in Pn were found in fruiting vs non‐fruiting plants on either a seasonal or a diurnal basis. Pn rates in swet cherry in the field were primarily affected by ontogeny and environment and not by sink strength.

“…The presence of fruit on spurs results in a decrease of the nucleic acid content and increase of the nucleohistone and this has a negative effect on the flower bud differentiation (18,19). Fruits reduce also the starch content in the fifth to sixth week after full bloom (48). According to this author the high starch content in the spurs cannot be regarded as a direct cause for flower bud initiation, but only as an excellent and rapid indicator of the direction of metabolic processes resulting from the low amounts of auxin and gibberellins in the surrounding tissues.…”
