“…Regarding to fruit load, in years of high yield, much phenolic compounds are allocated from leaves to the fruits (Julca et al, 2013) decreasing the defense of the plant. The phenolic compounds are considered anti-fungal compound (Subroto et al, 2019).…”

Introduction. Coffee (Coffea arabica L.) is an important crop in producing countries like Peru, where approximately two million families depend on its production, distribution, and marketing. But in recent years, climate change has increased the presence of coffee leaf rust - CLR (H. vastatrix), a disease that has decreased Peruvian production by up to 27%. Objective. Monitor the severity of CLR in different genotypes of coffee cv. Typica from April-2017 to March-2018. Material and methods. The experiment was carried out in the coffee germplasm bank at the Development Regional Institute (IRD)-Selva of the Universidad Nacional Agraria La Molina. The severity and the area under the disease progress curve (AUDPC) in the lower, middle, and upper part of coffee trees were quantified. Result. There was high severity and AUDPC in the dry season (low precipitation) compared to the rainy season (high precipitation). Severity and AUDPC gradually decreased from the bottom to the top of the plant (lower>middle>upper). Also, UNACAF-24A, UNACAF-16, UNACAF-158, and UNACAF-162 genotypes stood out by showing lowest severity (0-1.1 %) and AUDPC (0-714) in the experiment. Conclusion. In this experiment, the genotypes in dry season presented high peaks of severity and UDPC of CLR, meanwhile, in rainy season the presence of CLR was lower. However, in both seasons, severity and AUDPC gradually decreased from the lower third to the upper thirf of the plant. Finally, UNACAF-24A, UNACAF-16, UNACAF-158, and UNACAF-162 presented the lowest degrees of severity of CLR.

“…Flavonoids contain antioxidant activities that assist oxidative stress and prevent or treat various kinds of diseases. The study conducted by Subroto et al (2019) explains the correlation between flavonoid content and the resistance of arabica coffee plants against leaf rust disease. Compared to the mature phase of the plant, which is 12 years old, the addition of mineral formulations to a 1-year-old immature plant resulted in increased flavonoid content, polyphenol content, and antioxidant activity, reaching 27.027 mg GAE/g; 27.005 mg QE/g; and 59.46%, respectively (Figure 1).…”

Arabica coffee cultivation is limited by altitude, which affects its production. Some farmers in Jember Regency are innovating to grow arabica coffee in the lowland, but the potential for leaf rust disease is quite high. Plant natural resistance can be enhanced by adding minerals formulation (containing silica, iodine, and calcium). This research aimed to determine which phase is more effective for applying mineral formulation that induces plant resistance. The formulation was tested on arabica coffee plants grown at the lowland (460 masl) in Jember Regency on 12 years old (y.o) mature and 1 y.o immature plants. One formulation was dissolved in 14 L of water and applied by foliar feeding. The effect was analyzed using two-way T-test of two samples assuming unequal variances at 95% confidence level to determine the differences. The analysis showed that the plants supplemented with the formulation could increase the variables that supported the natural resistance of plants (both mechanically and through the production of chemical compounds), such as polyphenol content, flavonoids, antioxidant activity, total dissolved protein, vitamin C, reducing sugar, lignin, cellulose, hemicellulose, and iodine content in the plant. The response of the formulation application showed that the most resistance variables was better in 1 y.o immature plants than in 12 y.o mature plants. The application of mineral formulation in immature phase will have a better impact on increasing natural resistance, and it has the potential to be used as a supplement for arabica coffee plants cultivated in the lowland.

“…Menurut Utomo et al (2020), tumbuhan akan memproduksi senyawa yang bersifat antioksidan sebagai bentuk adaptasi terhadap suhu lingkungan yang tinggi, pada suhu yang lebih tinggi tanaman akan menghasilkan total flavonoid yang lebih tinggi pula sebagai pertahanan terhadap cekaman pada lingkungan. Senyawa flavonoid juga mempunyai kemampuan untuk pertahanan tanaman terhadap penyakit tanaman, hal ini diperkuat dengan penelitian yang sudah dilakukan olah Subroto, et al (2019), dimana semakin tinggi kandungan flavonoid pada daun kopi membuat tanaman mempunyai ketahan yang tinggi pula terhadap penyakit karat daun.…”

The coffee plant (Coffea) is one of the main types of plants in Indonesian society. Coffee plantations in Indonesia are very influential on the national economy. Several types of Arabica coffee clones began to be developed in order to have certain resistance to overcome attacks by various OPT which had a considerable impact on harvest success. The existence of resistance genes in plants, suitability with virulent genes and environmental influences become obstacles in making coffee clones that are resistant to certain pests. The physiological properties of coffee plants will affect the rate of growth and development of plants so that it will have an impact on their production. Selection of plant varieties is carried out to obtain certain superior characters with high yield potential. An analysis of the physiological properties must be carried out to identify and determine the desired selection criteria. This research was conducted at the Laboratory of the Faculty of Agriculture, University of Jember in June – end, using a single factor Completely Randomized Design (CRD), namely several Arabica coffee clones. Arabica coffee clone consists of 15 clones. Each clone was repeated three times, so that in this experiment there were 45 experimental units. Observational data obtained were analyzed using variance. If there is a significant difference between the treatments then proceed with Duncan's multiple range test at the 5% level. Based on the data and discussion of the research that has been done, it can be concluded that the fifteen arabica clones have different characteristics. The best Arabica coffee clone is the Sigararutang coffee clone which has a high value with (76.76 mg/g) chlorophyll content, (4.15 mg/g) flavonoid content, (7.07 mg/g) phenol content, ( 0.89 mg/g) dissolved protein content and (86.94 mg/g) antioxidant content. Keywords: Coffee clones, chlorophyll, flavonoids, phenols, soluble proteins, antioxidants
