Dynamism in Reserve Carbohydrates until the Following Growth Season in Japanese Apricot ^|^lsquo;Nanko^|^rsquo; Tree

Organ-dependent seasonal dynamism of three forms of carbohydrates in Japanese apricot

“…Our previous report indicated that carbohydrates assimilated in August contribute greatly to current twigs (Tsuchida et al, 2012). In this study, total 13 C concentration in the August application was high not only in current twigs (2-year-old twigs in the following year) but also in new twigs and in over 3-year-old twigs (Fig.…”

“…In our previous report (Tsuchida et al, 2012), we indicated that carbohydrates assimilated in September contribute greatly to roots. The results of the present study also show that total 13 C concentration in the fine and large roots in the September application was high level, at the beginning of May (Fig.…”

“…For Japanese apricot, we previously investigated changes in 13 C concentration of total carbohydrates until the following year and reported that the growth of young fruits and new leaves depends on reserve carbohydrates until the beginning of May of the following year (Tsuchida et al, 2012). Although assimilated carbohydrates are present in different forms, such as sugar, starch, and cell-wall material (CWM) (Ho, 1988), it has been unclear whether these three forms of reserve carbohydrate in Japanese apricot are distributed to and metabolized in each organ in the following year.…”
