Abstract

遺伝的に多様なトマト30品種・系統を供試し, 完熟果実におけるグルコースおよびフルクトース含量の作期および果房位による変動特性の差異を検討した.トマト品種・系統間における両成分含有量の相対的関係は, 栽培・環境条件の変動に対して比較的安定していた.また全体を通じてグルコース含量とフルクトース含量には高い正の相関がみられたが, 糖含量が高くなるほど全体に占めるフルクトース含量の比率は低くなる傾向がみられた.全品種・系統をこみにした作期・果房位ごとの平均値に対する, 対応する作期・果房位における糖含量の回帰分析から, 供試材料は, (1)作期・果房位ごとの糖含量が全供試材料の平均値とほぼ平等して変動する品種・系統, (2)作期・果房位間の変動が全供試材料の平均より大きい品種・系統, (3)作期・果房位間の変動が小さく安定した糖含量を示す品種・系統, (4)回帰直線への回帰が有意でなく糖含量変動が全供試材料の変動傾向と異なる変動を示す品種・系統が認められたが, 糖含量が高くかつ変動の小さい品種・系統は見出せなかった.

Varietal differences in glucose and fructose contents were evaluated in mature fruits of 30 genotypes grown under different cultivation systems. Varietal differences of glucose and fructose contents were comparatively stable among the cultivation systems. Although there is a high correlations between glucose and fructose contents, the percentage fructose to total sugar content was lower in the genotypes containing higher sugar content. There are no genotypes which has a high stable sugar content. Regression analysis of mean genotype and individual genotype contents of glucose and fructose reveals that the tomato genotypes were divided to four groups as follows. 1. Genotypes with regression coefficient almost equal to the mean genotype content. 2. Genotypes with significantly higher regression coefficient than the mean genotype content. 3. Genotypes with significantly lower regression coefficient than the mean genotype content. 4. Genotypes whose regression coefficient were not significant.
