The partnership ranging from outcrossing distance and you may cumulative physical fitness wasn’t high (quadratic regression: F
For 2 forest types when you look at the Sri Lanka’s wet area forests, fruits put more than doubled with outcrossing point, peaking on intermediate-point in this-forest crosses (1–10 kilometer based on varieties). In crosses between trees consuming independent forest reserves, although not, good fresh fruit put try somewhat less (otherwise almost very) for both varieties. However, seed germination and you will seedling level during the step 1 yr having Sh. cordifolia ideal hybrid vitality in-between-tree crosses. The effects from nearby-neighbor mating varied one of trees and you may variety; the latest suggest physical fitness price of nearest-neighbors mating in accordance with mating with moderately a great deal more distant locals is actually 45% getting S. rubicundum and you can 0% getting Sh. cordifolia. On the other hand, the newest exercise negative effects of anywhere between-forest crossing were generous both for varieties (52 and 70% in accordance with within this-forest crosses for similar a couple kinds). Crossing consequences diminished within degree out-of good fresh fruit put and you may step 1-yr-dated seedling dimensions; just the former was high both for types. Abilities indicate a strong potential for biparental inbreeding anxiety inside tree tree communities and limited reproductive isolation one of trees occupying the remaining forest reserves inside the Sri Lanka’s wet region.
