Abstract

Potato ( Solanum tuberosum L.) is one of the main commodities of food crops in Indonesia that are rich in vitamins, antioxidants, and carbohydrates. One of the most popular varieties of vegetable potatoes and become the leading varieties of producer farmers is Granola. Methyl jasmonate is a hormone known to modulate physiological events in plants such as encouraging tuber formation, functioning in vegetative development and fruit development. This study aims to evaluate the influence of methyl jasmonate on vegetative growth and potato tuber formation. In the fourth weeks, the methyl jasmonate applied with concentrations: 0 ppm (control), 12.5 ppm, 25 ppm, 50 ppm, 75 ppm, and 100 ppm. Measurement of plant height, number of leaves performed at the age of 4 weeks until the age of 7 weeks. The leaf area measured in seven weeks. The height of the plant measured in 4 weeks until 7 weeks. The leaf area measured in 7 weeks. Once the harvest performed, then measure the amount and weight of the tuber. Data were analyzed using ANOVA One way, if the data represent a significant difference, then continued with DMRT with an error rate of 5%. The results showed that methyl jasmonate administration generally had no effect on vegetative growth (plant height, leaf number, and leaf area) of the potato plant. The methyl jasmonate application tends to decrease the number of tubers formed but increases the size and weight of the tubers.

Highlights

Potatoes (Solanum tuberosum L.) are one of the C3 plant species and a member of the Solanaceae family
Fat, iron, potassium, phosphorus, vitamin B, vitamin C, and some vitamin A those are good for the body
Potato seeds of Granola variety (G4) that used in this research are 36 potatoes with 1-2 cm buds that planted in the mound-planting hole

Summary

INTRODUCTION

Potatoes (Solanum tuberosum L.) are one of the C3 plant species and a member of the Solanaceae family. Granola variety is dominating potatoes production, with a setting area reaching 80-90% of the crop. This variety is the best choice of the farmers because it is excellent yields, short life cycles, and wide adaptability. The potatoes productions affected by ideal location and adequate care. It influenced by the varieties of potatoes grown because every potatoes variety produces different potential results (BPTP SUMSEL, 2014). Biogenesis 25 defense responses to biotic and abiotic stresses, inducing a flowering, and aging This compound reported ruling the regulation of morphogenesis plant organ (Wei-Min et al, 2003). The response of methyl jasmonate and tuberonic acid (one of the methyl jasmonate derivatives) are thought to play a role in the formation of tuber formation
