| dc.description.abstract | This study aims to determine the effect of growth on the red mangrove
Rhizophora apiculata from the coastal distance to the north wind direction in
Pulau Sembilan village. The study was carried out from October 2020 to
december 2020. This study used a completely randomized design (CRD) with
distance treatment consisting of treatment 1 (planting distance from the beach 43
m), treatment 2 (planting distance from the beach 44 m), treatment 3 (planting
distance from the beach 45 m), treatment 4 (planting distance from the beach 46
m), treatment 5 (planting distance from the beach 47 m). The results of the
studyof plant spacing on R. apiculata mangrove seedlings for 12 weeks showed
that there was no significant effect. Based on the results of this study, it was
shown that the most optimal spacing was in the P5 treatment (47 m spacing)
where for the average seedling height value of 37.9 cm/12 weeks, the average
diameter value of 3.5 mm/12week. Anova test results show the value of Sig. >0.05
so it was concluded that the spacing of R. apiculata seedlings had no significant
effect on the parameters of plant height, stem diameter, number of leaves, wet
weight (leaves, stems, roots), dryweight (leaves, stems, roots), leaf area and leaf
area index. | en_US |
