Abstract

Tribulus terrestris merupakan salah satu tanaman obat yang mempunyai beragam manfaat antara lain sebagai diuretik (peluruh kencing), meningkatkan kadar hormon testoteron, memulihkan vitalitas dan menambah kebugaran. Hambatan dari budidaya tanaman ini secara konvensional adalah relatif rendahnya persentase daya kecambah, bentuk bijinya yang kecil dan budidaya yang tergantung pada musim tertentu. Perbanyakan tanaman dengan menggunakan biji secara in vitro merupakan solusi yang dapat digunakan untuk memperbanyak tanaman ini. Penelitian bertujuan untuk mengetahui pertumbuhan in vitro T. terrestris dengan perlakuan IBA dan BAP. Penelitian menggunakan Rancangan Acak Lengkap (RAL) yang disusun secara faktorial. Faktor pertama adalah konsentrasi IBA dan faktor kedua adalah konsentrasi BAP. Analisis data dilakukan dengan uji DMRT dan deskriptif. Hasil penelitian menunjukkan adanya interaksi pemberian IBA 1 ppm + BAP 1 ppm menghasilkan tinggi tunas tertinggi dan jumlah akar terbanyak, interaksi pemberian IBA 1 ppm + BAP 1 ppm dan IBA 1,5 ppm + BAP 2 ppm menginduksi saat muncul akar tercepat. Pemberian IBA secara tunggal tidak mempengaruhi pertumbuhan eksplan T. terrestris, pemberian IBA 0,5 ppm dikombinasikan dengan BAP 2 ppm dapat menginduksi panjang akar terpanjang. Pemberian BAP 1 ppm dapat menginduksi saat muncul tunas tercepat, saat muncul daun tercepat dan jumlah daun terbanyak.

Abstract

Purslane has many benefits as food or raw material for medicine. It is rich in beneficial compounds, such as omega-3 and vitamins. However, it has not been cultivated yet. Organic input in cultivation is essential to ensure food safety for humans. Using organic inputs can avoid the yield from chemical and biological contaminants that can threaten health. Thus, the source of growing media and fertilizer must be considered. Because the use of synthetic chemicals has residues that are harmful to the environment and human health. This research sought to identify the best combination of growing media and organic fertilizer to increase purslane yield. The experiment was conducted with a randomized block design with 2 factors and 3 replications. Organic fertilizers (guano, cow urine, and rabbit urine) and planting media (soil, soil + husk charcoal, soil + compost, and soil + husk charcoal) were the treatments assessed. The observation variables were planting media analysis, the number of leaves and branches, growth diameter, and fresh weight. The results show that the planting medium and organic fertilizer did not significantly affect the measured growth parameters. The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight

Abstract

Drought is widely recognized as one of the most critical environmental constraints limiting plant growth and development, particularly in medicinal species such as Echinacea purpurea. This research was conducted to assess the growth performance and drought tolerance of three E. purpurea accessions exposed to different watering regimes. The study employed a completely randomized design arranged factorially, consisting of two experimental factors, namely accession (three accessions) and watering interval (1, 3, 5, and 7 days), with each treatment replicated five times. Statistical analysis was performed using analysis of variance (ANOVA), and significant differences among treatments were further evaluated using Duncan’s Multiple Range Test (DMRT) at the 5% probability level. The findings revealed that watering interval had a significant influence on plant growth, while the effect of accession was less pronounced for most observed variables. Daily watering resulted in superior growth performance, as reflected by greater plant height and a higher number of leaves. In contrast, extending the watering interval led to a marked reduction in growth. Among the evaluated accessions, accession 3 consistently exhibited better adaptation under limited water availability. Furthermore, differences in root-to-shoot ratio under drought conditions suggest the occurrence of adaptive mechanisms that enable plants to cope with water deficit stress. Overall, the results indicate that watering interval plays a more decisive role than accession in determining the growth of E. purpurea, whereas accession 3 possesses the greatest potential for drought tolerance. Keywords: drought stress, Echinacea purpurea, growth, drought tolerance
