Pengaruh Media Tanam dan Intensitas Naungan terhadap Pertumbuhan Bakau Minyak (Rhizophora apiculata)

Abstract

Damage to mangrove forests has reduced the size forest area and the diversity of mangrove species. Improvement of mangrove forests require seeds with good growth and resistant to pests and diseases. The shade levels and growing media is a factor that affects plant growth. The purpose of this study was to analyze the effect of growing media and shade level on the growth of bakau minyak (R. apiculata). The study was conducted for 12 weeks and used a complete randomized design to analyze the data. The first factor was the growing media (A) with 3 levels of treatment, namely mudsoil (A0), mud and compost (A1), and mud, sand and compost (A2). The second factor was the shade level (N) with 3 levels treatment, namely the shade intensity 0% (N0), 50% (N1), and 70% (N2). The result of this study indicate that the shade intensity has a significant effect on the growth of Rhizophora apiculata, and the growing medium does not significantly affect the growth of Rhizophora apiculata. The best shade intensity for growth of R. apiculata is 0% (N0).

Growth Performance of Mangrove Seedlings Planted with Guludan Technique at Elang Laut Area, Muara Angke, Jakarta

“…Growth is the increase in the size of an organism due to the rise in the number and size of cells (Kusmana and Lestari 2021). The growth of mangrove seedlings observed in this study includes stem diameter, stem height, leaf count, and segment count.…”

“…Low light intensity causes suboptimal photosynthesis products, while high light intensity affects the stomatal cell activity in reducing transpiration, thereby inhibiting plant growth (Susilawati et al 2016). According to Kusmana and Lestari (2021), mangrove plants have the most efficient photosynthesis capability compared to other plants. Light is crucial for plant growth, so when plants receive sufficient light for their physiological activities, they tend to grow laterally (Karyati 2019).…”

“…Leaves are one of the plant organs responsible for photosynthesis, which absorbs and processes sunlight and carbon dioxide (Kusmana & Lestari, 2021). Rhizophora mucronata generally has large-sized leaves that are almost the same as mature leaves because, before they bloom, they function as wraps for the shoot tips (Haris 2019).…”

Use of Rhizophora apiculata and its cut-propagule seedling method for mangrove rehabilitation in Indonesia

“…This plant has characteristics that are different from the others, such as large, above-ground roots. These species were selected for restoration because of their excellent ability to stabilize mud sediments through extensive root systems [10].…”

The growth of mahogany seedlings (Swietenia macrophylla King.) in various planting media and shade intensity

“…Mahogany grown under low light intensity has a relatively small number of roots, resulting in a high ratio of shoots and roots (table 5). A small number of roots will cause less optimal absorption of water and nutrients to support plant growth [25]. Treatment without shade resulted in a lower shoots and roots ratio than treatment with shade.…”
