Syzygium rubicundum

Seed germination is very staggered in both pure (Stacy, Harischandran , and you will Gunatilleke, from inside the force) and you will greenhouse options, stretching more >cuatro mo. In the a hundred d once planting (whenever germination is actually ?95% complete), the latest rates out of seed products germinated have been average, ranging across the solutions out-of 21 to forty-two% from sown vegetables (imply = 36%; pooled all over maternal woods; Fig. 3a). With the exception of the new surprisingly higher germination speed observed towards the nearby-next-door neighbor therapy at Forest #3 (83.3%), the connection between crossing length and you will seed products germination are nearly identical to that particular having good fresh fruit set for that it varieties (Fig. 3a). And the data factors, imply seeds germination wasn’t somewhat other among treatments, neither certainly maternal trees (Desk 3A). Leaving out the newest unmarried outlier did not alter the Aong hands-pollination treatments, top indicate seed products germination coincided with level fresh fruit set in the an outcrossing length of just one–2 kilometres and you can is almost same as this new imply germination from open-pollinated seeds (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 (F_1,9 = 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 increases

On account of attrition from just one lives stage to the next, test designs of some therapy kinds was indeed lowest having estimates out-of seedling survivorship and you can increases, which may have impeded statistical examination. No high outcomes of possibly crossing medication otherwise maternal forest had been discovered getting sometimes size either in kinds (Dining table step 3). Leaving out selfed procedures seedlings out of S. rubicundum (N = 2), the latest imply survivorship rates out of seedlings during their first year is highest (>80%) for everyone service out-of both species. Both for kinds, top suggest seedling survivorship coincided to your faraway within-forest cures.

To own S. rubicundum, indicate seedling height on step 1 year postgermination improved that have outcrossing length, peaking on an enthusiastic intermate distance of just one–2 kilometres, and you will losing a little into longest distance crosses (Fig. 4a). To have Sh. cordifolia, suggest seedling level enhanced gradually that have outcrossing range, peaking in the longest-point cross (Fig. 4b). For both types, within-medication type when you look at the seedling peak was higher (Fig. 4). For S. rubicundum, adaptation in seedling level will be told me, at the least in part, by the staggered seeds germination.

Collective fitness

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: F_dos,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, F_1,12 = 1.69, P = 0.219), due to the strong near-neighbor effect on cumulative fitness.
