“…The low availability of nutrients gives a response to more root development so it becomes heavier because the roots are trying to get enough nutrients and water for plant development. Mastur [22] saying that plants that grow in conditions of lack of water will form a greater number of roots but with lower growth results than plants in sufficient water.…”

The application of vesicular arbuscular mycorrhizal (VAM) in powder dosage form has been used for a long time. However, this dosage form has a non-uniform application dose and allows VAM spores to be lost through wind and rainwater, so innovation is needed in the VAM dosage form. A study aimed at knowing dosage forms of VAM as a biological agent that affects colonization level and C3 plant‘s root morphology was carried out at Screen House Laboratory, Faculty of Agriculture, Animal Husbandry and Fisheries, University of Muhammadiyah Parepare using a factorial design based on completely randomized design (CRD). Treatment of VAM dosage forms (factor 1) used was powder (A1), sachet (A2), and tablet (A3). While the C3 plant species (factor 2) used were Puraria japonica (B1), Vigna radiata (B2), and Amaranthus gangeticus (B3). Observations were conducted on the percentage of colonized roots and the C3 plants’ root morphology. The results showed that the combined treatment of VAM dosage forms (powder, sachet, and tablets) and C3 plant species (Puraria javanica, Vigna radiata, Amaranthus gangeticus) showed significant effects on colonized roots percentage and C3 plant root morphology. So it can be recommended that VAM dosage forms (sachet and tablet) are efficient and effective for the mobilization and field application of VAM.

Physiological characteristics of IRR 400 series rubber clones (Hevea brasiliensis Muell. Arg.) on drought stress

et al. 2023

Background: Drought stress is one of the main causes of plant death. Strategies for plants survival are morphological adaptations, specific signaling pathways, and tolerance mechanisms. Rubber plantations have many uses, such as foreign exchange sources, job sources, forest revitalization, and a source of alternative wood for building materials and furniture. The rubber plant’s response to drought stress is a complex biological process. A tolerant rubber clone in a dry area is the right approach. The present study aimed to determine the mechanism of drought-tolerant clones, based on physiological characteristics, to obtain character selection and drought-tolerant clones early. Methods: The first factor examined for this work was clones (IRR 425, IRR 428, IRR 429, IRR 434, IRR 440, RRIC 100, and BPM 24) and the second factor was water content (30%, 60%, and 90%). The study was arranged on a factorial randomized block design and repeated three times. Characteristics observed were total sugar (µM), proline (mg/L), chlorophyll a, b, total (µg/mL), hydrogen peroxidase (µmol/g), ascorbate peroxidase (unit/mg), superoxide dismutase (unit/mg), and peroxide dismutase (unit/mg). Results: The tolerance ability of the IRR 400 series rubber clones to drought stress was determined by observing the characteristics of sugar total and proline. The concentration of total sugar and proline were higher when the plant was treated with a lower water content. The selected clones tolerant to drought stress are RR 425 and IR 434 with high total sugar content and proline. Other characteristics, namely chlorophyll a, b, and total, as well as hydrogen peroxidase, ascorbate peroxidase, super oxide dismutase, peroxide dismutase, cannot be used as selection characteristics for this study. Conclusions: This drought study of IRR 400 clones with varying water content percentages illustrated that the total sugar and proline characteristics could be used to distinguish tolerance levels from other observed characteristics.

Background: Drought stress is one of the main causes of plant death. Strategies for plant survival include triggering of specific signaling pathways and tolerance mechanisms. Rubber plantations have many uses, including in forest revitalization and as foreign exchange sources, job sources, and as an alternative source for building materials and furniture. The rubber plant’s response to drought stress is a complex biological process. Planting tolerant rubber clone in drought prone areas would be more appropriate. The present study is aimed to identify drought tolerant traits in order to select drought-tolerant clones at juvenile stage itself. Methods: The first factor examined for this research was the clones (IRR 425, IRR 428, IRR 429, IRR 434, IRR 440, RRIC 100, and BPM 24), with water content (30%, 60%, and 90%) as the second factor studied. The study was arranged on a factorial randomized block design and repeated three times. Characteristics observed included total sugar (µM), proline (mg/L), chlorophyll a, b, total (µg/mL), hydrogen peroxidase (µmol/g), ascorbate peroxidase (unit/mg), superoxide dismutase (unit/mg), and peroxide dismutase (unit/mg). Results: The tolerance ability of the IRR 400 series rubber clones to drought stress was determined by observing the concentrations of total sugar and proline, which were higher when the plant was treated with a lower water content. The selected clones tolerant to drought stress were RR 425 and IR 434 with high total sugar and proline. Other characteristics, namely chlorophyll a, b, and total, as well as hydrogen peroxidase, ascorbate peroxidase, superoxide dismutase, and peroxide dismutase, cannot be used as selection characteristics for this study. Conclusions: This drought study of IRR 400 clones with varying water content percentages illustrated that the total sugar and proline characteristics could be used to distinguish tolerance levels.
