Syzygium rubicundum
Seeds germination are highly staggered both in absolute (Stacy, Harischandran, and Gunatilleke, from inside the push) and you may greenhouse configurations, stretching more >cuatro mo. From the one hundred d just after planting (when germination is actually ?95% complete), new percent from seeds germinated were reasonable, starting round the service off 21 to forty two% off sown seed products (imply = 36%; pooled across the maternal trees; Fig. 3a). Aside from this new oddly large germination speed noticed into the nearby-neighbor procedures during the Tree no. 3 (83.3%), the connection anywhere between crossing distance and you can seed products germination was almost the same to this having good fresh fruit in for so it varieties (Fig. 3a). In addition to all analysis circumstances, imply seeds germination was not significantly some other among solutions, neither certainly one of maternal woods (Desk 3A). Excluding the unmarried outlier did not alter the Aong hand-pollination services, height suggest seed products germination coincided with peak fruits place on an enthusiastic outcrossing distance of 1–2 km and you can are almost identical to brand new mean germination off open-pollinated vegetables (Fig. 3a).
Shorea cordifolia
Germination of experimental seeds was rapid and fairly even across treatments (mean = 62%; range: 55–72% at 45 d; Fig. 3b). A steady increase in mean seed germination with outcrossing distance is apparent, but not significant (Fstep one,9 = 1.02, P < 0.34, R 2 = 0.40; Fig. 3b). Mean seed germination was not significantly different among treatments, nor among maternal trees (Table 3B). Interestingly, mean seed germination for all hand-pollination treatments exceeded that of open-pollinated seeds (Fig. 3b). While the reason for this observation is not known, the latter estimates were based on much larger sample sizes and therefore may be more robust.
Seedling survivorship and you can gains
Because of attrition from one lives stage to another, take to types of a few therapy groups had been reasonable getting prices out of seedling survivorship and you will progress, which have hampered mathematical assessment. Zero significant outcomes of either crossing medication or maternal tree was receive having either level either in varieties (Desk step three). Leaving out selfed therapy seedlings away from S. rubicundum (N = 2), the fresh indicate survivorship price off seedlings in their first year is actually highest (>80%) for everyone services away from both kinds. Both for species, top imply seedling survivorship coincided on faraway within-forest cures.
Having S. rubicundum, imply seedling level in the 1 yr postgermination increased with outcrossing point, peaking within a keen intermate length of 1–2 kilometres, and you may losing slightly on the longest length crosses (Fig. 4a). To have Sh. cordifolia, suggest seedling peak improved steadily that have outcrossing distance, peaking on longest-distance cross (Fig. 4b). For variety, within-treatment adaptation in the seedling level are large (Fig. 4). To have S. rubicundum, type during the seedling sito single incontri fitness top can be said, no less than simply, from the staggered seeds germination.
Collective exercise
For each species, the cumulative fitness of each treatment class was calculated as the standardized product of the four fitness measures (see Fig. 5). For both species, the distribution of cumulative fitness with respect to crossing distance was similar to that for fruit set (Fig. 5). For S. rubicundum, variation in cumulative fitness among treatments was highly significant (Table 3A); mean cumulative fitness of the distant within-forest treatment was 4–25 times the means for other hand-pollination treatments and twice that of open-pollinated flowers. The relationship between outcrossing distance and cumulative fitness was nearly significant (quadratic regression: F2,ten = 3.84, P = 0.056). Mean cumulative fitness (relative) was not significantly different between the distant between-forest treatment (mean = 0.07) and all within-forest outcrossed classes combined (mean = 0.24, Fstep 1,twelve = 1.69, P = 0.219), due to the strong near-neighbor effect on cumulative fitness.
