Exploration and Morphological Characterization of Vegetative Part of Avocado at Bebesan Subdistrict Central Aceh District, Indonesia

Abstract

Purpose-The purpose of this research was to get the initial information about the phenotype diversity of avocado plants and as an information source of Acehnese avocado germplasm. Methodology-This research was conducted at Bebesen sub-district Aceh Tengah District, from March to October 2017. Exploration was conducted using the descriptive method with purposive sampling. Plants observed in accordance with predetermined criteria namely plants that have been several times fruitful and preferred by consumers. Originality-The research shown that the avocado plants in the Bebesen sub-district have a high degree of diversity. The diversity can be seen from canopy width, stem circumference, plant height, stem surface, tree shape, number of branches, branch shape, leaf length, leaf width, leaf area, and leaf shape. The number of superior avocado plants that were sampled was 15 accessions. The similarity level of superior avocado accession in the Bebesen sub-district ranged from 0.34 to 1.00.

Characterization of Tanzanian Avocado Using Morphological Traits

“…Most of the local avocado varieties (seedlings), in Njombe urban, were already being replaced by the commercial cultivars, notably 'Hass' and 'Fuerte'. Similarly, Ismadi and Hafifah [23] reported only rough and very rough trunk surfaces among 15 avocado accessions in the Central Aceh district of Indonesia. According to Bergh [5], the tree bark of the Guatemalan and Mexican avocado races are less rough, while those of the West Indian race are rougher.…”

“…Some of these shapes have been previously reported by Abraham et al [4] and Nkansah et al [24], who together described seven leaf shapes among avocado plants in Ghana. Ismadi and Hafifah [23] reported only lanceolate (73.33%) and oblong lanceolate (26.67) leaf shapes among 15 avocado accessions in Indonesia. The higher number of leaf shapes (11) found in the present study could be due to a larger sample size.…”

Comparison of Morphological and Genetic Characteristics of Avocados Grown in Tanzania

“…Different markers have been used in avocado germplasm characterization, management, and conservation. Morphological markers were used to characterize avocado germplasm in California [ 7 ], Florida [ 8 ], Ghana [ 9 , 10 ], Mexico [ 11 ], Indonesia [ 12 ], and Tanzania [ 13 ], among others. However, besides being labor intensive, morphological traits are associated with some shortcomings, such as low variability (polymorphism) and heritability, late expression, influence by environmental factors, and subjectivity [ 14 , 15 ].…”

Pertumbuhan dan Hasil Tanaman Selada (Lactuca Sativa L.) Akibat Perlakuan Pupuk Kandang Jangkrik dan Pupuk Kandang Ayam

“…Penelitian berbagai jenis tanaman hortikultura telah mulai dilakukan tim penelitian Fakultas Pertanian Universitas Malikussaleh. Jenis tanaman buah yang sudah diteliti adalah tanaman durian (Handayani & Ismadi 2017;Handayani et al 2019;Liwanza et al, 2019), manggis , alpukat (Ismadi et al 2018); (Ismadi et al 2019), nanas (Liwanza et al, 2022). Jenis tanaman sayuran yang sudah diteliti adalah bawang daun (Paiman et al 2019), dan pakcoy (Usnawiyah et al, 2022), Tujuan penelitian untuk mengetahui adanya pengaruh pupuk kandang jangkrik dan kandang ayam terhadap pertumbuhan dan hasil tanaman selada.…”
