Morphological characteristic of local clove varieties in East Halmahera

Abstract

The distinctive characteristics of local clove plants could be evaluated through morphological observations. The research was assessed during June - October 2019 in Talaga Jaya, South Wasile, East Halmahera. The study was conducted by survey method with the age of observed plants were more than 10 years old and which species consist of 10 productive trees, selected randomly. The research using local clove with comparative superior varieties of Afo. Leaf, flower, fruit, seed, and the symptom of blister blight disease were observed at 1 m2 area on each tree. Form of the trees, stems, branches, leaves, flowers, fruits, and seeds were observed. The results showed that the characteristics morphology of local clove varieties was similar to Afo. The disease severity of blister blight in this study was mild with a 4,28% disease intensity. Morphological characteristics similar to Afo cloves and mild disease intensity of blister blight indicate that local clove varieties have the potential to be developed into new varieties.

The effect of Arbuscular Mycorrhizal Fungi (AMF) on agronomic characteristics of clove seedlings of superior local variety of East Halmahera

“…Clove (Syzygium aromaticum L.) is one of the main plantation commodities in Indonesia and is known to have many varieties, one of which is the local superior clove from East Halmahera. This local clove variety has morphological characters similar to Afo clove and is widely cultivated by farmers in East Halmahera (Cahyaningrum et al, 2021). Conditions in the field show that many plants are old and damaged, so rejuvenation is required.…”
