Syzygium rubicundum
Seeds germination is extremely staggered in both sheer (Stacy, Harischandran, and you may Gunatilleke, within the drive) and greenhouse configurations, extending more than >cuatro mo. On 100 d just after planting (whenever germination is ?95% complete), the percent regarding vegetables germinated was basically moderate, starting all over solutions away from 21 so you can 44% regarding sown seed products (suggest = 36%; pooled across maternal woods; Fig. 3a). Aside from new oddly highest germination rate observed with the nearest-neighbors procedures during the Forest # 3 (83.3%), the partnership anywhere between crossing length and you can seeds germination was nearly the same to this to have fruit set for so it types (Fig. 3a). Plus all the data situations, indicate seed germination wasn’t significantly some other among services, neither among maternal trees (Table 3A). Excluding the latest single outlier did not change the Aong hands-pollination services, height imply seed products germination coincided which have peak fruit place within a keen outcrossing distance of just one–dos kilometres and you will try almost just like the fresh imply germination out-of open-pollinated seed products (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 (F1,9 = 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 will development
On account of attrition in one existence phase to a higher, sample types of a few procedures kinds was reasonable to possess prices out of seedling survivorship and you will gains, that have hampered analytical examination. No extreme ramifications of both crossing procedures otherwise maternal forest have been discover to possess both measure in either varieties (Dining table step 3). Excluding selfed therapy seedlings regarding S. rubicundum (N = 2), the newest suggest survivorship price out of seedlings during their first year try large (>80%) for all sitios de citas para solteros White Sites services away from each other types. For both variety, peak indicate seedling survivorship coincided on distant within-forest medication.
To possess S. rubicundum, suggest seedling level at step one year postgermination improved that have outcrossing length, peaking at the a keen intermate point of just one–2 kilometer, and you may dropping slightly towards longest range crosses (Fig. 4a). Having Sh. cordifolia, mean seedling height improved continuously that have outcrossing distance, peaking during the longest-length get across (Fig. 4b). For both species, within-procedures variation when you look at the seedling height is higher (Fig. 4). Having S. rubicundum, variation inside seedling top would be explained, about to some extent, 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: Fdos,10 = 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,several = 1.69, P = 0.219), due to the strong near-neighbor effect on cumulative fitness.
