Abstract

Purple corn is a cereal plant that has health benefits. Purple corn contains anthocyanins, which are useful as anticancer and antioxidants, and has high nutritional value. Improving the quality of corn production can be done through plant breeding. This study aimed to determine the value of variability, heritability and expected genetic advance of F3 purple corn from open-pollinated hybridization. The research was conducted from December 2020 to April 2021 at Universitas Bangka Belitung. The study used a single plant design experimental method. The selection used was ear to row. The results showed that the color of the seeds of the F3 line was dominated by orange. The lines have different quantitative characters. The lines that have the most purple color were F3-PXU-11-25, F3-PXU-6-16, and F3-PXU-11-20. The value of phenotypic variability and genotypic variability of the broad criteria was found in the weight of corn cob with husk and without husk. The broad heritability was high on the weight corn cob with and without husk. The value of the expected genetic advance progress of the high criteria was on the characters of cob length, the weight of 100 seeds, the weight of corn cob with husk, and the weight of corn cob without husk.

Abstract

Appropriate plant spacing and new superior rice varieties are essential factors in achieving high yields. This study aimed to evaluate rice varieties and jajar legowo planting systems that increase growth and yield during the dry season in East Nusa Tenggara. The research was arranged in a split plot in a randomized complete block design with two replications. The rice varieties (main plot) consisted of upland rice (Inpago 8 and Inpago 12) and lowland rice (Inpari 32 and Ciherang). The planting systems (sub-plot) consisted of a square system 20 cm × 20 cm, jajar legowo 2:1 (30 – 60) cm × 15 cm, jajar legowo 2:1 (25 – 50) cm × 12.5 cm, jajar legowo 2:1 (20 – 40) cm × 10 cm, and jajar legowo 4:1 (20 – 40) cm × 10 cm. The results indicated that Inpago 12 planted with the jajar legowo 2:1 (25 – 50) cm × 12.5 cm resulted in higher growth and yield than those planted with the square system. All tested varieties were not significantly different, while the planting systems were statistically different. The planting system of jajar legowo 2:1 (25 – 50) cm × 12.5 cm obtained higher growth and yield than other planting systems.

Abstract

Indonesia has a wide area of acid-dry land with potential food crops, especially soybeans. The study was conducted to determine the effect of arbuscular mycorrhizal fungi (AMF) as seed coat of soybean on ultisol, applied with various doses of lime. The study was conducted in Ultisols in Kuranji Village, Kuranji District, Padang City, West Sumatra, Indonesia. The experiment was arranged in a split-plot design. The main plot was the dose of CaCO3 lime with two levels, namely 0 (without lime) and lime equivalent to 2 x Al-dd. Subplots were the application of seed coat in five ratios of AMF inoculant: former soybean planting soil, consisting of 0:4, 1:4, 2:4, 3:4, and 4:4. Each treatment was replicated three times. Data were analyzed for variance and the least significant difference (LSD) test with a significance level of 5%. The results showed that applying lime could increase P uptake in soybean plants by 25.58%. The highest soybean yield was 2.046 tons ha-1, yielded from seed coat treatment with a ratio of 2:4 without lime and the lime treatment equivalent to 2xAl-dd without seed coat.

Abstract

Abscisic acid (ABA) is a growth regulatory substance that plays an important role in various processes in the cell, such as plant adaptation to environmental threats, seed development, dormancy, budding, plant development, and fruit ripening. Another important role of abscisic acid is increased antioxidant capacity, total phenol content, total carotenoid, and anthocyanin content. The content of bioactive compounds such as antioxidants is a parameter of fruit quality that can decrease due to improper postharvest handling. Many postharvest treatments have been conducted to maintain or delay the declining of bioactive compounds in fruits. This current research was done to determine the various abscisic acid concentrations on papayas and cucumbers' bioactive content. The experiment was arranged in a completely randomized design with three replications. The data were expressed as mean ± standard deviation and analyzed using SAS (Statistical Analysis Software). Significant differences between means were determined by the Student's t-test, with p-values less than 0.05 considered significant. Results of the research regarding color testing, DPPH, total phenol content, and total soluble solids showed that abscisic acid with 380 µMol or 100 mg/l concentration could increase the total phenol content, antioxidant capacity, and total soluble solids in papayas (climacteric fruit) during the ripening. However, applying abscisic acid with 100 µMol on cucumbers (non-climacteric fruit) showed no significant effect on total phenol, antioxidant capacity, and soluble solids compared to the control group. The results showed that during the ripening of climacteric fruit, ABA enhanced the content of bioactive compounds and improved postharvest quality. This effect was not observed in non-climacteric fruit.

Abstract

The development of oil palm nurseries in Bengkulu is constrained by plant media, such as ultisol soil, which has low nutrients. Nutrients in ultisol can be equipped by organic matters such as manure and liquid organic fertilizer (LOF). Moreover, the light intensity also could affect seeds growth. This research aimed to determine the improvement of oil palm in pre-nursery as affected by LOF, types of manure application, and shade to obtain the best treatment combination. The research was conducted from June until September 2021 in Beringin Raya, Bengkulu city. The study was arranged in a split-plot design in a completely randomized block design consisting of 3 factors with three replications. The main plot was shade percentage ((N1=50% dan N2=75%), the subplot was liquid organic fertilizer doses ((B1=0%, B2=5% and B3=10%), the sub subplot was the types of manure (P1=cow manure, P2=chicken manure, P3=goat manure, and P4= without manure). The observation was made on the growth components of oil palm seedlings until 3.5 months. There was an interaction between shade, LOF, and types of manure to the number of leaves. There was no interaction between LOF and types of manure. The shade did not affect the growth factors of the seeds. Applying 10% LOF can improve the growth of oil palm seedlings. Chicken manure has the highest variable value on the hump diameter and the number of leaves seedlings.

Abstract

Nano cattle bone ash can reduce requirement for SP-36 and increase pod yield. This study aimed to examine the physiological response, growth, and yield of edamame soybean in entisol of concentration and frequency of foliar application of nano cattle bone ash and SP-36 fertilizer.The research was conducted an experimental method which arranged in a Randomized Completely Block Design (RCBD) which consists of factor concentration (0.15, 0.30, and 0.45%) and frequency (2, 3, and 4 times). In control treatment was given 100% recommended dose SP-36, whereas between concentration and frequency foliar were given 50%. The findings demonstrated that foliar application of nano cattle bone ash with 50% SP-36 resulted in higher leaf dry weight and pod yield per plant as compared to control, increasing pod production per plant by 21.7%. The results of this study concluded that nano cattle bone ash can replace a half dose of SP-36 and increase pod yield. In the future, it is expected that the use of nano cattle bone ash can be applied into soybean cultivation and reduce use of SP-36 fertilizer.

Abstract

Durian (Durio spp.) is a germplasm with a relatively high species diversity, with an estimated 27 species worldwide. However, the existence of several species has been threatened. This study aimed to reconstruct the DNA barcode of the durian and its relatives (Durio spp.) and analyze the genetic diversity and its relationship based on the internal transcribed spacer (ITS) region. Sixteen sequences of durians ITS were collected from GenBank (NCBI) and analyzed in silico using the BLAST, MultAlin, and MEGA-X software, then reconstructed phylogenetically by the UPGMA and Maximum Likelihood methods. The results show that the ITS region of Durio spp. has a base length of about 702 bp, where several mutations occur, substitution (transversion and transition) and indel (insertion and deletion). At the nucleotide level, this germplasm shows a relatively high diversity of 0.065. The cluster analyses (UPGMA and Maximum Likelihood) can separate this germplasm into four clusters and five main clades, respectively. In this study, D. zibethinus, the most popular species in the Durio genus, is closely related to D. lowianus and far from D. griffithii. This information is beneficial as reference data to support durian conservation and breeding programs, locally and globally, especially in Indonesia.

Abstract

This study aimed to determine the appropriate time for the chlorophyll fluorescence light curve measurement in sago palms and to avoid high values variations. The photosynthetic status of three-year-old sago palm seedlings was evaluated through the chlorophyll fluorescence measurement. The chlorophyll fluorescence light curve of measurement was evaluated under different daytime measurements. Observations on DFm/Fm’ and ETR vs. irradiances were conducted on sago palm leaves in the morning, midday, and afternoon with light and dark adaptation. The highest ETRmax value was found under a light-adapted leaf; however, the Eopt value could not be obtained. Morning time measurement on the dark-adapted leaf is the most appropriate method and time to get an Eopt value with high ETRmax.
