Abstract

Beauveria bassiana (Balsamo) Vuill. is an entomopathogenic fungi can live endophytic on different kinds of plants. B. bassiana also play a role as growth promoters that improves seed germination and growth of plant. The effect of increased duration of seed treatment with Beauveria bassiana on seed germination and seedling parameters in chili were assessed in laboratory and field conditions. Chili seeds were soaked in the conidial suspension of B. bassiana in a concentration of 1 x 108 conidial / ml or in sterile distilled water for 3, 6, 9, and 12 h. Seed germination percentages and the vigor index were significantly affected by the application of B. bassiana. Overall, seed germination, the vigor index and plant growth of chili were significantly enhanced as seed treatment duration increased. B. bassiana can also accelerate seed germination of chili and increase of seedling growth. Soaking the seeds with a B. bassiana suspension for 9 hours is the best time to increase of seed germination and seedling growth of chili

Abstract

High temperatures can affect plant morphophysiological changes and enzyme denaturation that can interfere with the germination process. This research aims to study the effect of temperature changes on the α-amylase enzyme activity of several rice varieties germination. The research applies Factorial Experiment in Completely Random Design, where the first factor is four levels of rice varieties, Anak Daro, Batang Piaman, Cisokan, and Inpari 30. The second factor is temperature level, 28 0C, 32 0C, 36 0C, 40 0C, 44 0C and 48 0C. Results showed that the activity of the α -amylase enzymes of the four varieties increased when the temperature increased to reach the optimal temperature, and denaturation began to occur above that temperature. The highest enzyme activity of α-amylase of Anak Daro, Cisokan and Inpari 30 varieties at 48 0C is 0,14 micromol, 0,365 micromol dan 0,191 micromol. In contrast the optimum enzyme activity of α-amylase of Batang Piaman variety at a temperature of 40 0C is 0,237 micromol and when the temperature rises to 48 0C a decrease in the activity of the α-amylation enzyme is 0,138 micromol. The variation in the activity of α-amylase enzymes in the four varieties is probably due to genetic differences and sucrose content. The Batang Piaman and Cisokan varieties can only germinate up to 36 0C, while the Daro and Inpari 30 varieties can germinate up to 40 0C.

Abstract

Rice (Oryza sativa L.) is an important food crop that is the staple food of more than half of the world's population because it contains nutrients that the body needs. Information on the genetic diversity of local rice scattered in the Kuantan Singingi Regency is still not available. Due to this fact, the genetic diversity of local rice can be identified by DNA analysis. A DNA-based molecular marker that can be applied as a plant genetic marker is SRAP. The SRAP (Sequence Related Amplified Polymorphism) marker system is one of the powerful molecular tools for the clarification of individual sex and estimating the genetic diversity of plant species. This study aims to determine the genetic relationship of rice plants in the Kuantan Singingi Regency through SRAP markers. Twenty-four (24) local genotype samples were used in this study. Observational data were processed using Ms. software. Excel and (NTSYS-pc) version 2.02. The results obtained 17 fragments in Primer M, which resulted in a similarity analysis between 71% to 100%. There are two (2) groups at 75% similarity, then there are five (5) groups at 81% similarity and there are four (4) groups that have 100% similarity. The results of this study are expected to be taken into consideration in developing rice breeding strategies in the future.

Abstract

More foods are required to fulfill human need. The limitation of the farming area is leading to intensification system in crop cultivation, so the use of chemical properties and environmental destruction cannot be denied. However, this industrial practice in the crop system has caused many adverse effects on ecological balance and human health. Many severe impacts of industrial agriculture practices have been reported, including soil erosion, groundwater contamination, loss of productivity, depletion of fossil resources, air pollution, new threats to human health and safety. Many experts agreed that sustainable agriculture seems to be an effective way to solve these issues. Modern plant breeding is now a popular approach to provide superior crop cultivars that can minimize adverse effects of agriculture practices because humans can recognize and manipulated genes through this method. Recently, the application of molecular markers in plant breeding selection has been brought enthusiasm for plant breeders. Marker-assisted selection (MAS) has been evidenced to be a beneficial technique in plant breeding. Through this approach, the selection process of parents and progenies in the breeding process could be more efficient. Plant breeding is influential in crop production achievement because this effort is connected with the adaptability and stability of the varieties in many different environmental circumstances. Plant breeding also focuses on agriculture sustainability due to its effort to produces durable disease resistance, abiotic stress tolerance, nutrients, and water-use efficiency.

Abstract

West Sumatra was declared as a center for Indonesian cocoa in the western portion. Almost all areas in West Sumatra are suitable for cocoa cultivation, so the cocoa planting area covers almost all the districts in the province. However, West Sumatran Cocoa production decline occurs because cocoa plantations are still mostly cultivated with smallholder plantations. The occurrence of land conversion and reduced land carrying capacity, including soil fertility, is due to the continuous use of inorganic fertilizers, which results in a decrease in the ecological quality of the land. Efforts to improve land conditions biologically by utilizing soil biotechnology. One of the soil microbes that can be utilized is Arbuscular Mycorrhizal Fungi (AMF). AMF that live in a symbiotic mutualism with plant roots and helps the absorption of plant nutrients and live in various places. The study aimed to identify arbuscular mycorrhiza Cocoa rhizosphere three districts, West Sumatra province, from the month of November 2020 to May 2021. The results showed the number of spores and diversity of AMF. The number of spores was 67-218 spores per 20 g soil. The root colonization was in the range of 21.3 - 24.6%. While the AMF diversity before trapped found three types of sport Glomus sp., Acaulospora sp., dan Gigaspora sp
