Abstract. Gustiar F, Lakitan B, Budianta D, Negara ZP. 2023. Assessing the impact on growth and yield in different varieties of chili pepper (Capsicum frutescens) intercropped with chaya (Cnidoscolus aconitifolius). Biodiversitas 24: 2639-2646. Intercropping chaya and chili plants is advantageous as it can boost land productivity and increase farmer income. However, the growth of the chili plant is more likely to be hampered by the shade formed by the canopy of the chaya plant. Therefore, this study aimed to investigate the response of chili to the shade of the chaya plant canopy and identify varieties that can thrive in intercropping systems. The experiment was arranged based on a split-plot design with a planting pattern as the main plot, consisting of chili monoculture, intercropping of chaya-chili, and intercropping of pruned-canopy chaya with chili. Three chili varieties, i.e., Rajo, Taruna, and Bara, were the subplots with four replications. Chaya plants were planted at a distance of 200 x 200 cm. Chaya-chili intercropping was done by inserting two rows of chili plants with a distance of 50 x 50 cm between rows of chaya plants. The results showed that chili pepper planted in an intercropping system exhibit an etiolation effect as indicated by a taller stem but with fewer leaves than the chili plants cultivated with a monoculture system. The shading effect of the chaya plant resulted in lower leaf temperature of the chili peppers in intercropping system. Pruning treatment on the shoots of chaya plants positively impacted the growth and yield of chili plants, which was indicated by an increase in biomass weight and fruit yield. The Bara variety was harvested two weeks earlier and produced higher fruit yields compared to Rajo and Taruna varieties. The growth and yield of chili plants were relatively comparable between the monoculture and intercropping system if the canopy pruning in chaya plants was carried out, especially in the Bara variety.

Background Capsicum (Solanaceae) is a globally important vegetable crop and is also used therapeutically in traditional medicine systems. However, little is known of the genetic variation within the commonly grown cultivars, the evolutionary relationships and differences in the chloroplast (cp.) genomes between Capsicum species remain unclear. Results The cp. genomes of 32 Capsicum varieties in three species from 6 countries were investigated. The cp. genome of Capsicum was found to be ~ 156 kb in length and to contain 113 unique genes, of which 79 encoded proteins, 30 encoded transfer tRNAs, and 4 were for ribosomal RNAs. The 32 varieties that we chose for study represented 13 genotypes, containing a total of 608 indels, 83 SNPs, 47 SSRs and 281–306 repeat sequences. We then included several previously sequenced Capsicum cp. genomes, and found that the nine investigated species showed a number of differences in the characteristics of the four IR boundaries, and it was the non-coding regions that contained the most variable regions. We conducted a phylogenetic reconstruction using the cp. genomes of 43 representative species of Solanaceae, and the resulting phylogeny generally reflected the currently accepted classification, with the species of the pungent group having close relationship with one another. Conclusions This study provides a comprehensive analysis of Capsicum chloroplast genomes, revealing significant variations in IR boundaries and other genomic features. These findings enhance our understanding of Capsicum evolution and genetic diversity.
