“…the northeast populations across the species' geographic range (Hagiwara 1977). A common garden study of F. crenata saplings confirmed this clinal variation in leaf size and, moreover, revealed that saplings with large leaves have narrow, vertically extended crowns, while those with small leaves have flat, horizontally extended crowns, due to their different shoot dynamics (Hiura 1998). Fujii et al (2002) examined chloroplast DNA (cpDNA) variation in F. crenata populations across the species' range, and found a strong geographic structure among 13 haplotypes, with a subdivision into two major lineages: one mainly distributed along the Sea of Japan side and the other chiefly along the Pacific side of the Japanese Islands.…”

In order to examine whether seedlings of nonnative genetic lineages had been planted, we compared chloroplast DNA haplotypes in plantations and neighboring natural populations of Fagus crenata in Nagano Prefecture, Japan. This region was chosen for study because there are abundant natural F. crenata populations with different haplotypes, and because the species is also frequently used for afforestation in the area. We sampled 159 trees from 30 populations of the species across most of its natural range in the region, and 136 trees from 20 plantations of the species, ranging in age from 3 to 17 years. Six single nucleotide polymorphisms and four insertions/deletions in two chloroplast DNA regions (trnL-trnF and trnK) were analyzed in each of the sampled individuals in order to determine their haplotypes. Four haplotypes (B, D, E and F) were detected in the natural populations, and these exhibited a clear geographical structure; in contrast, only two haplotypes (A and B) were found in the plantations. We found that 15 out of the 20 plantations-located in central and southern areas on the Pacific side of Honshu, where the natural populations contain haplotypes D, E, and F, and where the climate is characterized by dry, cold winters-had been established using seedlings with haplotypes A and B derived from the Sea of Japan side of the Japanese Islands, where it snows heavily. The risks associated with planting seedlings of inappropriate lineages are discussed.

Effects of Herbivory and Light Conditions on Induced Defense in Quercus crispula

Understanding the induced resistance to herbivory in plants is important in elucidating plant life-history traits. Resistance to herbivory takes two basic forms: defense and tolerance. Induced defense plays an important role in the ecology and evolution of plant-herbivore interactions. it has become increasingly clear that induced defenses to herbivory are complex traits involving the interaction of intrinsic and extrinsic factors. In this study, we investigated the effects of herbivory and the availability of light on induced resistance in Quetcus crispula saplings, and the relation between defense and tolerance involving photosynthesis and growth. We conducted field experiments with herbivorous insects under two light conditions. As an induced defense, the leaf mass per area increased with herbivory regardless of the amount of light available, and the concentration of condensed tannin was significantly higher when light was plentiful. On the other hand, as induced tolerance, the photosynthetic rate decreased with herbivory under conditions of ample light. In conclusion, we found that both the availability of light and herbivory affected defense and tolerance in Q. crispUa. In addition, we suggest that the interaction between defense and tolerance was noticeable when much light was available because of the photosynthetic reduction caused by herbivory.

“…Short shoots of the former will therefore have a longer stem lifespan than short current-year shoots of the latter. The difference in stem life-span (Millington andChaney 1973, Addicott 1982, Bilbrough andRichards 199l, Ginocchio and Montenegro 1992, Buck-Sorlin and Bell 1998) among these species will presumably be revealed by studying shoot dynamics (e.g., Maillette 1982, Chester and McGraw 1983, Jones and Harper 1987, Hiura 1998, Stoll and Schmid 1998.…”

Variations in morphology and biomass allocation of current-year shoots were investigated in saplings of ten cooltemperate tall tree species. In all the species, the ratio (leaf mass)/(stem mass) was greater in shorter current-year shoots than in longer current-year shoots. This indicates the presence of shoot differentiation, where shorter currentyear shoots are oriented to light-capture or leaf-display and longer current-year shoots are oriented to crown-expansion or space-acquisition. However, two types of differentiation were found. In type I, shorter current-year shoots had greater ratios of (leaf area)/(stem length) than longer current-year shoots and a ratio of (stem mass)/(stem length) comparable to that of longer current-year shoots. In type II, shorter current-year shoots had disproportionately smaller ratios of (stem mass)/(stem length) than longer currentyear shoots and a ratio of (leaf area)/(stem length) comparable to that of longer current-year shoots. Type I corresponds to the apparent differentiation of dwarf shoots. Type II was newly found in this study. I hypothesize that shorter current-year shoots in type I have stout stems for supporting offspring shoots in spite of severe self-shading, whereas shorter current-year shoots in type II avoid selfshading at the expense of stout stems. Implications of the two types of shoot differentiation are discussed in relation to foliage-crown dynamics.Key words: Biomass allocation -Frequency distribution of shoot length -Leaf display index -Shoot differentiation -Stem length -Stem mass per unit stem lengthCurrent-year shoots are fundamental units for tree crown development, and the relative importance of light-capture (i.e., leaf-display) and crown-expansion (i.e., space-acquisition) for current-year shoots is not uniform even within a single tree. Therefore, the differentiation of current-year shoots for light-capture or crown-expansion is an effective Present address:Abbreviations: LDI, the ratio of (leaf area)/(stem length) of a currentyear shoot (leaf display index); LSR, the ratio of (leaf mass)/(stem mass) of a current-year shoot (leaf-stem ratio); LSRPo,, the ratio of (total leaf mass)/(total stem mass) of the sampled current-year shoots (be., leaf-stem ratio of a population of current-year shoots) tactic for constructing an efficient assimilation system (Halle et a/, 1978, Steingraeber and Waller 1986, Seino 1998. Crown-expansion is more important than light-capture for current-year shoots facing an open space with high light availability; the opposite is true for current-year shoots in the inner and lower portions of a crown and for current-year shoots facing the crown of neighboring trees (Remphrey et a/. 1983, Borchert and Tomlinson 1984, Jones and Harper 1987. The differentiation of current-year shoots is likely to be universal among tree species.Patterns of differentiation of current-year shoots are closely related to the productive strategies of trees. For example, the total amount of foliage and the leaf-stem balance of an assimilation system...
