Abstract

Sorgum adalah tanaman famili gramineae yang pada umumnya memerlukan unsur hara Si sebagai unsur beneficial. Kandungan Si di tanah terus berkurang akibat tidak ditambahkan Si dari luar dan tidak ada pengembalian Si dari organ tanaman pada saat panen. Tujuan penelitian ini adalah untuk mengetahui dampak nanosilika terhadap pertumbuhan vegetatif tanaman sorgum dengan perlakuan nanosilika pada dosis yang berbeda. Penelitian menggunakan Rancangan Acak Lengkap (RAL) satu faktor, yaitu konsentrasi pupuk nanosilika dengan dosis perlakuan : 0 ml/L; 2,5 ml/L; 5 ml/L; 7,5 ml/L; 10 ml/L masing-masing perlakuan dengan 5 ulangan. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT) pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa pemberian pupuk nanosilika dengan konsentrasi 2,5 ml/L dapat meningkatkan bobot segar tajuk, bobot kering tajuk, dan luas daun. Dosis 2,5 sampai 7,5 ml/L meningkatkan tinggi tanaman dan dosis 7,5 ml/L sampai 10 ml/L meningkatkan kandungan klorofil a dan klorofil  total,  namun pemberian pupuk nanosilika tidak berpengaruh nyata terhadap kandungan klorofil b, jumlah daun, bobot basah dan kering akar, bobot malai, bobot segar dan kering biji, dan bobot kering 100 biji.Sorghum is a gramineae family plant which generally requires the nutrient Si as a beneficial element. The Si content in the soil continues to decrease due to no addition of Si from outside and no return of Si from plant organs at harvest. The aim of this research is to determine the impact of nanosilica on the vegetative growth of sorghum plants with nanosilica treatment at different doses. The research used a Completely Randomized Design (CRD) with one factor, namely the concentration of nanosilica fertilizer with a treatment dose of: 0 ml/L; 2.5 ml/L; 5ml/L; 7.5 ml/L; 10 ml/L for each treatment with 5 repetitions. Data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan's Multiple Range Test (DMRT) at a confidence level of 95%. The research results showed that applying nanosilica fertilizer with a concentration of 2.5 ml/L could increase fresh shoot weight, shoot dry weight and leaf area. A dose of 2.5 to 7.5 ml/L increases plant height and a dose of 7.5 ml/L to 10 ml/L increases chlorophyll a and total chlorophyll content, but the application of nanosilica fertilizer has no significant effect on chlorophyll b content, number of leaves, wet and dry weight of roots, panicle weight, fresh and dry weight of seeds, and dry weight of 100 seeds

Abstract

Pertumbuhan dan produksi cabai dapat ditingkatkan melalui metode pemangkasan pucuk. Aplikasi BAP dan GA3 setelah pemangkasan pucuk dapat mempengaruhi pertumbuhan vegetatif tanaman yang selanjutnya berdampak terhadap pembungaan dan produksi cabai. Penelitian ini bertujuan untuk mengkaji pengaruh aplikasi hormon BAP dan GA3 dengan berbagai rasio konsentrasi setelah pemangkasan pucuk terhadap pertumbuhan vegetatif dan pembungaan tanaman cabai merah keriting (Capsicum annuum L.). Pemangkasan pucuk dilakukan pada fase vegetatif akhir, diikuti dengan aplikasi BAP dan GA3. Parameter yang diamati meliputi durasi muncul tunas cabang lateral, jumlah dan panjang cabang lateral, luas daun, kandungan klorofil total, alokasi biomassa, dan periode muncul bunga. Hasil penelitian menunjukkan bahwa aplikasi rasio konsentrasi BAP dan GA3 secara signifikan meningkatkan jumlah dan panjang cabang lateral, luas daun, dan mempercepat waktu muncul bunga dibandingkan kontrol. Perlakuan dengan rasio konsentrasi BAP 0 ppm : GA3 100 ppm dan BAP 200 ppm : GA3 100 ppm memberikan hasil terbaik dalam pertumbuhan vegetatif dan mempercepat pembungaan. Penelitian ini memberikan kontribusi dalam pengelolaan hormon tanaman pasca pemangkasan untuk meningkatkan produktivitas cabai. The growth and yield of chili peppers can be enhanced through the method of shoot pruning. The application of BAP and GA3 after shoot pruning can affect the vegetative growth of plants, which subsequently impacts the flowering and production of chili peppers. This study aims to examine the effects of applying BAP and GA3 hormones at various concentration ratios after shoot pruning on the vegetative growth and flowering of curly red chili peppers (Capsicum annuum L.). Shoot pruning was carried out at the late vegetative phase, followed by the application of BAP and GA3. The observed parameters included the duration of lateral bud emergence, the number and length of lateral branches, leaf area, total chlorophyll content, biomass allocation, and the flowering period. The results showed that the application of BAP and GA3 concentration ratios significantly increased the number and length of lateral branches, leaf area, and accelerated the flowering time compared to the control. Treatments with the ratios of BAP 0 ppm : GA3 100 ppm and BAP 200 ppm : GA3 100 ppm yielded the best results in vegetative growth and accelerated flowering. This study contributes to the management of plant hormones post-pruning to enhance chili productivity.

Abstract

The Asteraceae family has a wide distribution supported by its adaptive capabilities, including seed morphological traits that influence physiological performance. This study aims to determine the morphological characteristics, physiological performance of seeds, and their correlation in members of the Asteraceae family at the foothills of Mount Ungaran. The findings of this study can also be applied and provide opportunities for further research on seed physiology, particularly in Asteraceae species. The observed parameters in this study include morphological traits (growth habit, achene type, achene length, pappus type, and pappus length) and physiological traits (maturation period, imbibition, germination percentage, germination rate, mean germination time, and vigor) in Asteraceae species at the foothills of Mount Ungaran. The study employs analysis of variance (ANOVA) and Principal Component Analysis (PCA) to assess the significant influence of species differences on seed physiological traits and the strong correlation between morphological and physiological characteristics. Species variation significantly affects seed trait diversity, with morphology playing a crucial role in determining physiological performance and supporting adaptive strategies for survival.

Abstract

Kualitas tanaman hias daun ditentukan oleh pertumbuhan dan nilai estetika tajuk.  Hormon sitokinin berpengaruh terhadap pertumbuhan dan produktivitas tajuk. Penelitian ini mengkaji respon pertumbuhan tajuk, morfologis daun dan nilai estetika tanaman hias Epipremnum aureum terhadap berbagai konsentrasi hormon sitokinin sintetis (6-benzylaminopurine /BAP). Aplikasi BAP dengan konsentrasi 0, 5, 25 dan 125 ppm diberikan melalui metode spray pada daun stek E. aureum umur 3 MST. Pemberian BAP dilakukan satu kali dalam seminggu hingga tanaman berumur 6 MST, selanjutnya diberikan dua hari sekali hingga penelitian berakhir pada 9 MST. Respon tanaman diamati pada umur 9 MST meliputi: respon pertumbuhan (jumlah dan luas daun, panjang batang, berat segar daun, berat segar batang), morfologis daun (warna dan indeks warna daun), dan nilai estetika (corak daun). Hasil penelitian menunjukkan aplikasi BAP 5 ppm, 25 ppm dan 125 ppm meningkatkan pertumbuhan tajuk dibanding kontrol. Peningkatan konsentrasi BAP hingga kisaran 80-100 ppm meningkatkan pertumbuhan tajuk, namun konsentrasi di atas 100 ppm menunjukkan kecenderungan penurunan pertumbuhan. Secara morfologis, peningkatan konsentrasi BAP meningkatkan warna hijau dan indeks warna daun serta pembentukan corak daun, terutama pada konsentrasi BAP 125 ppm. Daun menunjukkan warna hijau yang lebih intens dan corak semburat kekuningan yang lebih tinggi dibandingkan perlakuan lainnya.  Konsentrasi BAP yang optimal untuk meningkatkan pertumbuhan tanaman ditemukan pada kisaran 80-100 ppm. Secara keseluruhan, aplikasi BAP meningkatkan pertumbuhan tajuk dan memperbaiki kualitas estetika daun tanaman E. aureum. The growth and aesthetic value of the shoot determine the quality of ornamental foliage plants. Cytokinin hormones influence the growth and productivity of the shoot. This study examines the response of canopy growth, leaf morphology, and the aesthetic value of the ornamental plant Epipremnum aureum to various concentrations of synthetic cytokinin hormone (6-benzylaminopurine/BAP). BAP application at concentrations of 0, 5, 25, and 125 ppm was applied through a spray method to the leaves of 3-month-old E. aureum cuttings. BAP was used once a week until the plants were 6 months old, then twice every two days until the study ended at 9 months. The plant responses were observed at 9 months of age, including growth responses (number and size of leaves, stem length, fresh leaf weight, and fresh stem weight), leaf morphology (color and leaf color index), and aesthetic value (leaf patterns). The results showed that applying BAP at 5 ppm, 25 ppm, and 125 ppm increased canopy growth compared to the control. Increasing the BAP concentration to 80-100 ppm enhanced canopy growth, but concentrations above 100 ppm tended to decrease growth. Morphologically, increasing BAP concentrations improved the green color and leaf color index and the formation of leaf patterns, especially at the 125 ppm concentration. The leaves showed a more intense green color and higher yellowish patterns than the other treatments. The optimal BAP concentration for improving plant growth was 80-100 ppm. Overall, the BAP application enhanced canopy growth and improved the aesthetic quality of E. aureum leaf plants.
