Abstract

The Indonesian government has been promoting the use of true seed of shallot (TSS) for shallot production due to its higher productivity potentials and greatly reduced risk of disease transfer. This research was conducted at Leuwikopo experimental station, Department of Agronomy and Horticulture, Bogor Agricultural University, West Java, Indonesia, in 2015. The aim of the research was to study TSS production from small size shallot sets “Bima Brebes”, an easy to flower shallot cultivar.  The trial was arranged in a completely randomized block design with two factors; BAP concentration i.e. 50, 100 150, 200 ppm as the first factor and the sizes of mother bulbs, i.e. small (3-4 g) and medium (5-10 g), as the second factor. The results showed that the vegetative growth of plants from the two bulb sizes were similar. TSS production and TSS quality from small size (3-4 g) bulbs was also comparable to that of medium size shallot set, except for 1000 seeds weight in which medium size mother bulb produced heavier 1000-seeds weight than that of small size shallot set. Therefore small size shallot set can potentially be useful for TSS production.

Abstract

The pineapple vegetative propagation method using crown leaf bud cuttings has potential to produce seedlings of greater uniformity and in larger quantities than other methods. This study, aimed to explore the potential eff ects of concentration and frequency of Benzylaminopurine (BAP) application for increasing the production and quality of pineapple seedlings from crown leaf bud cutting propagation. The experiment used a randomized complete block design (RCBD) with two factors. The fi rst factor was the concentration of BAP (0, 200, 400, 600, 800 ppm) and the second factor was the frequency of BAP application (1, 2, 3 times). Furthermore, this study investigated the eff ects of applying mycorrhizae to accelerate seedling growth and improve seedling quality during production from crown leaf bud cutting propagation. The experiment used a RCBD with one factor (dose of mycorrhiza: 0, 50, 100, 150, 200 spores). The results indicated that the eff ects of concentration and frequency of BAP application and their interaction increased seed production as determined by sprout cuttings at 5 weeks after planting by applying 600 ppm 2 times. Generally, with increasing concentration and frequency of BAP application, leaf chlorophyll content was reduced. However, the application mycorrhiza positively infl uenced the production of seedlings from pineapple crown bud cuttings and improved seedling quality as measured by root dry weight, chlorophyll content, root infection, and phosphatase enzyme activity.

Abstract

Seed testing is important for determining seed quality. Seed testing must be easy, quick, and accurate. This study aimed to develop a rapid method for assessing peanut seed quality using Urine Sugar Analysis Paper (USAP). USAP is commonly used for detecting human urinary glucose and is currently being developed for evaluating seed quality. Three experiments were conducted. Experiment 1 investigated the most effective seed-cutting size (whole, halved, and seeds cut into six pieces) and soaking periods (0, 3, 6, and 9 hours) based on glucose and protein leakage, as well as specific gravity of the soaking water. The optimal method identified in Experiment 1 was then used to test all five seed lots in USAP Experiment 2, which aimed to evaluate the effectiveness of seed quality testing using the USAP method at various levels of seed viability. Experiment 3 investigated the correlation between USAP test results and other viability and vigor test parameters, including germination percentage, first count germination, speed of germination, and electrical conductivity. The results of experiments indicated that cutting seeds into six pieces and 6 6-hour soaking period was the most optimal. Experiment 3 showed that USAP testing correlated with viability and vigor testing across various peanut varieties. Protein and density testing using USAP were negatively correlated with germination percentage, first count germination, and germination speed parameters, but positively correlated with electrical conductivity. However, glucose leakage was not detectable using USAP.
