英文摘要	Trigonobalanus doichangensis is recognized as a rare and endangered plant of China. The morphological and physiological traits of fruits were investigated in one population over 2 years (2006-2007) and in four populations during 2007 in order to facilitate ex-situ conservation and eventual reforestation through planting of propagules. The results indicated that morphological traits including fruit length, fruit width and 1,000-fruit weight showed significant variation among individual trees within populations (P < 0.01), however, not among populations. And each of them had significant positive correlation with each other (P < 0.01). Seed abortion occurred, and there was significant variation in percentage of fruit fill among populations and among individual trees within populations, whereas, percentage of fruit fill showed no correlation with the morphological traits. As for fruit germination, germination percentage, germination index and vigor index presented significant variation among populations and among individual trees within populations. The three germination-related indices had significant positive correlations with each other (r >= 0.9, P < 0.01) and with percentage of fruit fill (r > 0.86, P < 0.01), however, possessing weak correlations with morphological traits. It was also found that each of the traits mentioned above showed significant variation among individual trees within years, however, not between years. In addition, more than 48% of the variation occurred among individual trees both within populations and within years in all the fruit characters. We suggest that collecting fruits from various individuals at each of populations will be the preferred strategy to conserve the most genetic diversity of the species.
