Syzygium rubicundum
Seed products germination are highly staggered in natural (Stacy, Harischandran, and you may Gunatilleke, inside force) and you can greenhouse setup, stretching more than >cuatro mo. From the 100 d just after planting (when germination try ?95% complete), the fresh new percentages of seed products germinated was in fact modest, varying across services off 21 in order to 49% out of sown vegetables (mean = 36%; pooled across the maternal woods; Fig. 3a). Aside from the latest strangely higher germination price seen towards nearest-next-door neighbor medication in the Tree #3 (83.3%), the partnership ranging from crossing distance and vegetables germination is actually nearly similar to that particular to have good fresh fruit in for that it kinds (Fig. 3a). Along with all data situations, suggest seeds germination was not significantly various other certainly services, neither among maternal trees (Desk 3A). Leaving out the brand new single outlier did not change the Aong give-pollination treatments, height mean seeds germination coincided having level fruit lay during the a keen outcrossing length of 1–2 km and you may is almost identical to the brand new mean germination out of open-pollinated seed (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 1,nine = 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 may gains
On account of attrition from sito di incontri buddisti one lifestyle stage to another location, decide to try brands of some medication groups was in fact lowest to possess quotes out-of seedling survivorship and growth, which may have hampered mathematical evaluating. Zero extreme ramifications of possibly crossing therapy or maternal forest was basically receive to have both measure in either kinds (Dining table step three). Leaving out selfed procedures seedlings off S. rubicundum (N = 2), the imply survivorship rates from seedlings throughout their first 12 months is higher (>80%) for everyone service of each other varieties. Both for varieties, height indicate seedling survivorship coincided into distant inside-tree medication.
Getting S. rubicundum, suggest seedling peak at the step 1 yr postgermination enhanced which have outcrossing length, peaking on a keen intermate length of just one–dos kilometer, and you may shedding some to the longest length crosses (Fig. 4a). For Sh. cordifolia, suggest seedling top increased steadily that have outcrossing length, peaking within longest-point mix (Fig. 4b). For species, within-cures adaptation from inside the seedling level was higher (Fig. 4). For S. rubicundum, variation during the seedling level is said, 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: F2,10 = 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 one,several = 1.69, P = 0.219), due to the strong near-neighbor effect on cumulative fitness.
