“…Stomata is one part of the plant that is modified from the epidermis, in the form of hair and grows around the surface of the plant leaves [31]. In the process of photosynthesis, stomata act as a door for CO2 in and out of plants to be exchanged for oxygen released into the environment [32]. There was no difference in stomata density in all accessions (Table 6).…”

Sintrong (Crassocephalum repidiodes) is an indigenous vegetable in several regions in Indonesia. It is nutritious and contains bioactive ingredients that are beneficial to health. Although it has been consumed as a vegetable, it has not been cultivated so people only harvest it from nature. The study aimed to obtain information about its morphological and physiological characteristics to develop cultivation technology. In situ exploration was conducted in three areas namely Bogor, Cianjur, and Purwakarta in the highlands and lowlands. Observations were made on morphological and physiological characters, namely leaf characters, pigment content, flavonoids, and phenol content. The results showed that there were 4 accession groups based on morphophysiological characters. In addition, all accessions showed that they contained beneficial non-nutritive chemical components, namely flavonoids in the range of 1152.39-1596.15 mg QE 100 g−1 dry matter and total phenol 722.96-2345.97 mg GAE 100 g−1 dry matter.

“…Sebaliknya, semakin besar ukuran stomata maka jumlah stomata dalam satu bidang pandang semakin sedikit. Hal ini sebagaimana yang dilaporkan oleh [25] yang menyatakan bahwa jumlah stomata pada setiap jenis tanaman dapat dipengaruhi oleh ukuran stomata. Apabila ukuran stomata besar maka jumlahnya sedikit, sebaliknya apabila stomata berukuran kecil maka jumlahnya lebih banyak [26].…”

The aim of this study was to identifiy the stomata morphological characters of Pteridophyta in the â€‹â€‹Parangkikis Pagerwojo Waterfall area, Tulungagung. The first step of stomata observation was preparation of the abaxial leaf slice. The preparation was carried out by the replica method. Stomata character studied include types and size of stomata, the number of stomata and epidermis cells, and value of the stomatal index. The result of this study showed that stomata types of Pteridophyta were polocytic and anomocytic. Of the 15 Pteridophyta species observed, the all of stomata type were polocytic, except Selaginella which had type stomata anomocytic. Stomata oval was found in Selaginella intermedia and Phymatosorus sp., slightly oval (kidney) was found in Asplenium apogamum, Dryopteris sp., Asplenium normale, Nephrolepis bisserata, Nephrolepis davallioides, Asplenium nidus, and Pteris longipinnula sp., spherical was found in Dicranopteris linearis, Cyclosorus arida, Goniophlebium percussom, and Goniophlebium manmiense, and nonconcave was found in Coniogramme fraxinea. Stomata size affected the number of stomata. If the size of the stomata was small, the number of stomata was increasing. The highest number of stomata was found in D. linearis, which was 362, while the least number of stomata was S. intermedia, which was 18. Data on the number of stomata and epidermal cells were used to determine the stomatal index. The highest stomata index was found in D. linearis, which was 22.05% and the lowest was C. fraxinea, which was 5.44 %. Keywords: Anomocytic, Parangkikis, polocytic, Pteridophyta, stomata

Peningkatan produktivitas jagung sangat dipengaruhi oleh karakter fisiologi seperti klorofil dan stomata daun. Hal ini sangat berkaitan dengan proses fotosintesis yang dipengaruhi oleh kandungan nitrogen dan air dalam tanah. Penelitin ini bertujuan untuk mengetahui pengaruh penggunaan pupuk slowrelase dari biochar tongkol jagung berbasis NPK terhadap karakter dan kolerasi fisiologi tanaman jagung. Metode penelitian merupakan percobaan lapangan menggunakan Rancangan Acak Kelompok untuk menguji empat jenis perlakuan, yakni Pupuk kimia (P0), pupuk slowrelase berbasis NPK (P1), pupuk slowrelase diperkaya urin sapi (P2) dan pupuk slowrelase diperkaya urin sapi dan bakteri (azotobacter dan basillus)(P3). Parameter yang diamati terhadap karakter fisiologi tanaman jagung, yakni Chlorofil content Indeks (CCI), kehijauan daun, jumlah stomata dan ukuran stomata serta korelasi antar karakteri fisiologi. Hasil penelitian menemukan bahwa pemberian pupuk slowrelase diperkaya urin sapi dan bakteri memberikan hasil terbaik pada CCI dan kehijauan daun yakni 44,64 dan 3,77 berbeda nyata hingga sangat nyata dengan pemberian pupuk kimia (16,27; 2,77). Untuk tindak adaptasi pemberian pupuk slowrelease diperkaya urin sapi dan bakteri mengurangi jumlah ukuran stomata dengan hasil yang lebih kecil (78,33) berbeda nyata dengan pemberian pupuk slowrelease pengkayaan bakteri (P0,P1 dan P2). Terdapat korelasi yang nyata antara CCI dan jumlah stomata terhadap kehijauan daun. Berdasarkan hal tersebut, maka penggunaan pupuk slowrelase yang diperkaya urin sapi dan bakteri menjadi strategi adaptif usaha tani jagung menghadapi perubahan iklim. Increasing corn productivity is strongly influenced by physiological characters such as chlorophyll and leaf stomata. This is closely related to the photosynthesis process which is influenced by the nitrogen and water content in the soil. This research aims to use slow-relase fertilizer from NPK-based corn cob biochar on the characteristics and physiological correlation of corn plants. The research method was a field experiment using a Randomized Block Design to test four types of treatment, namely chemical fertilizer (P0), NPK-based slowrelase fertilizer (P1), slowrelase fertilizer enriched with cow urine (P2) and slowrelase fertilizer enriched with cow urine and bacteria (azotobacter and bacillus )(P3). Observation parameters on the physiological characteristics of corn plants, namely Chlorophyll content Index (CCI), leaf greenness, number of stomata and stomata size as well as correlation between physiological characteristics. The results of the research found that the application of slowrelase fertilizer enriched with cow urine and bacteria gave the best results in CCI and leaf greenness, namely 44.64 and 3.77, significantly to very significantly different from the application of chemical fertilizer (16.27; 2.77). For adaptation, giving slow-release fertilizer enriched with cow urine and bacteria reduced the number of stomata sizes with smaller results (78.33), significantly different from giving slow-release fertilizer enriched with bacteria (PO, P1 and P2). There is a real correlation between CCI and the number of stomata on leaf greenness. Based on this, the use of slowrelase fertilizer enriched with cow urine and bacteria is an adaptive strategy for corn farming to face climate change.
