Effect of Priming on Vigor of Germinated Chili (Capsicum annum L.) Seeds in Aluminium Stress Conditions

Abstract

Seed germination in ultisol is a problem. Ultisol has a low pH, poor in nutrients and organic matter, and high Al content. The low physiological quality of seeds is also a limiting factor. The purpose of this study was to determine the effect of priming on the seed vigor of two chili varieties whose seeds have expired and have not expired. This experiment consisted of 2 experiments, namely Experiment 1, which used seeds that had expired (deteriorating), and Experiment II, which used seeds that had not expired (non-deteriorating). This study was structured using a completely randomized design (CRD) which was repeated three times. This experiment is factorial. The first factor is priming, consisting of five levels: control, immersion in water, 30% PEG, 50 ppm GA3, and 1% KNO3. At the same time, the second factor in the first experiment was the seeds of the Tanjung 2 and Kencana varieties that had expired (deteriorating). In the second experiment, the second factor was the seeds of the Tanjung 2 and Kencana varieties that had not expired (non-deteriorating). The data obtained were analyzed using the R statistic program with a 5% HSD test. The results showed that priming with 50 ppm GA3 and 1% KNO3 increased the vigor of seeds that had expired (deteriorating). Meanwhile, priming with water and 1% KNO3 increased the vigor of seeds that had not yet expired (deterioration). The Kencana variety has a higher vigor than the Tanjung 2 variety on expired seeds. In seeds that have not yet expired, both varieties have the same good vigor.

Seed priming of stored seeds on seed germination, vegetative performance, flowering, and proline content in chili under water stress condition

“…Moreover, [10] and [25] stated that triggering the metabolic process through seed drying and hydration prior to germination due to priming treatment could increase the percentage and rate of germination, and improve seedling growth either under normal or under various abiotic stresses. The results were also consistent with earlier studies that found that hydro, osmo, or hormone priming improved seed germination in stored okra seeds [26], and chili [28,29]. [4] further stated that invigoration strategies such as hydro priming, osmo conditioning, and hormonal priming were able to shorten the emergence time of stored seeds in various horticultural crops.…”

Capsicum annum L. Storability Vigor and Estimation of Its Genetic Parameters

“…Remarks: KN1 = Normal number of sprouts on the first count on the 7th day 6. Electric Conductivity is measured in the following way, after a quick depreciation treatment, the seeds are weighed, then put into a cup containing 25 aquadest noodles and covered with aluminum foil, after being left for 6 hours at a temperature of around 10°C (Agustiansyah et al, 2021). The seeds are filtered and the aguabides from soaking the seeds are measured DHL.…”

IMPROVEMENT OF PHYSIOLOGICAL QUALITY AND SEED GROWTH OF EXPIRED CAYENNE PEPPER (Capsicum frutescens) THROUGH INVIGORATION TECHNIQUE USING YOUNG CORN EXTRACT

“…Pada proses invigorasi yang panjang terjadi peningkatan mutu terhadap kecepatan tumbuh, keserempakan perkecambahan, serta pengurangan tekanan lingkungan yang suboptimal selama proses invigorasi. Agustiansyah et al, (2021) menyampaikan perlakuan benih kedaluarsa menggunakan teknik perendaman dan penambahan fitohormon dapat meningkatkan daya berkecambah. Benih kedaluarsa yang dikecambahkan tanpa penambahan zat pengatur tumbuh atau zat kimia lainnya akan menghasilkan nilai berkecambah yang relatif rendah karena viabilitas dan vigor benih menurun.…”
