Abstract

Mutualistic plant-microbe interaction can increase the availability or absorption of nutrients and affect plant metabolism. Metabolomics is the study of all metabolites contained in living beings at a specific time. This research aims to study the effect of metanotrophic bacteria (BGM 9 isolate) and nitrogen-fixing bacteria (ITJ 7 isolate) on rice plant growth and reveal the information about metabolites produced by rice plant interacting with the bacteria. Three rice plant varieties (Ciherang, Hawara Bunar, and IR64) were grown on liquid media (Yoshida solution) and were inoculated with the bacteria five weeks after planting. Metabolites in the liquid media were detected seven days after inoculation using Liquid Chromatography-Mass Spectrometry and analyzed using MassLynx v4.1. The results showed that the bacterial inoculation had significant effect on rice growth. Chromatograms resulted from LC-MS showed there are 34 unique peaks from Ciherang, 21 unique peaks from Hawara Bunar, and 30 unique peaks from IR64. The unique peaks in each variety were affected by the bacteria inoculation treatments.

Abstract

Rice is an important food crop with a crucial role in global food security. Study on correlation between morphoagronomic traits and yield is an important step in the development of superior rice varieties. Research data were collected from 20 rice varieties grown in the experimental field. A total of 10 morphoagronomic trait variables were measured, including plant height, number of productive tillers, flowering age, dry weight of biomass, hollow grain, 1,000-grain weight, grain weight, panicle number, panicle length, and harvest index. Data were analyzed using variance, correlation, and principal component analyses. The results of PCA showed that 3 principal components (PC) explained 80.88% of the data variation. PC1 was associated with plant height, flowering age, biomass dry weight, empty grain, panicle length, grain weight per clump. PC2 was associated with 1,000-grain weight and harvest index, while PC3 was associated with number of productive tillers and number of panicles. Correlation analysis showed that 1,000-grain weight was positively correlated with harvest index, while biomass dry weight was negatively correlated. These results suggest that all observed morphoagronomic traits except biomass dry weight have an important role in increasing rice yield. Furthermore, the results of this study provide basic informations for the development of high-yielding rice varieties.

Abstract

IPB CP1 potato is a raw material for potato chips. The advantage of IPB CP1 potatoes is their high yield. Challenges in potato production are limited areas with optimal altitude and condition as well as low quality and quantity of seeds. Utilizing a mid-altitude area for potato cultivation is one of the solutions to increase potato seed production. This study aimed to compare the growth and production of IPB CP1 G0 seed tuber in a greenhouse and screenhouse in mid-altitude with different numbers of shoot cuttings per polybag. This research was conducted with two factors. The first factor is the use of growth plant houses, i.e. greenhouse and screenhouse. The second factor is the number of shoot cuttings per polybag, i.e. 2 and 3 shoot cuttings per polybag. Growth parameters observed included plant height, number of nodes and leaves, and fresh and dry weight of shoots. The production parameters observed included the number as well as fresh and dry weight of tubers. The growth and production of IPB CP1 potatoes grown in the greenhouse were better than those grown in the screenhouse. The number of cuttings per polybag did not affect the growth and production of IPB CP1 potato.
