“…Light distribution is an important factor affecting maize photosynthesis [16]. The results of rescobch by [17], showed that light intensity had an effect on plant height, number of leaves, leaf width-length ratio, plant dry weight and root-tooth ratio of maize plants. Several maize varieties grown under the shade of oil palm aged 12 ycobs showed significant differences in plant height, amount of chlorophyll a and b, number of leaves, leaf length, leaf area, segment length, weight of cob without skin, dry cob weight, and seed weight.…”

The development of maize in shade areas is one of the efforts to increase the national maize production.The study objective was to determine the growth and yield adaptation of hybrid maize in shaded areas. The study was conducted in the sengon forest area of Kalices Village, Patehan District, Kendal Regency from March to September 2020. The study was designed using a randomized block design with split-split plots with treatments including: a) shade density (0%, 20% and 40%) as the main plot; b) cultivation technology (PTT and existing farmers) as sub-plots; and c) varieties (JH 37, Nasa 29 and Bisi 18) as sub-plots. Each treatment was replicated 3 times in order to obtain 18 treatment combinations and each replication was planted in a plot with a size of 350 m2. The parameters observed included the percentage of plants growing, plant height at harvest, age 50% male flowers, age 50% female flowers, cob height, cob length, cob weight, cob diameter, number of rows per cob, number of seeds per row, weight of dry seeds, seed moisture content, yield per plot and yield per hectare. The data were processed by analysis of variance and if there is a significant difference, it was further tested with DMRT at the 5% level. The results showed that the shading had a very significant effect on most of the yield components, namely cob length, number of seed rows per cob, wet and dry shell weight per 10 cobs, wet stubble weight per 10 plants, wet stubble weight, and dry shell weight. However, there is no significant effect on the growth components of growth power, cob circumference and cob position. The growth and yield adaptation of maize was better at 20% shade density compared to 40% shade density. On land with a shade density of 20%, the highest productivity was obtained in the Bisi 18 of 5.9 t/ha with a potential yield of 62.7%, followed by Nasa 29 of 5.8 t/ha with a potential yield of 58.41%, and JH 37 as much as 5.2 t/ha with a potential yield of 25%.

“…Wilson (1988) stated that increasing root temperature increased root activity in absorbing nutrients so that it could accelerate root formation. Akmalia and Suharyanto (2017) said that the lowest light intensity would allocate the biomass towards the canopy so that the value of the root-crown ratio is smaller.…”

Abstract. Firdaus NM, Mudyantini W, Sugiarto. 2020. Physiological and phytochemical characters of Eleutherine palmifolia affected by treatment of variation in light intensity and water capacity. Cell Biol Dev 4: 26-39. Bawang dayak (Eleutherine palmifolia (L.) Merr.) is one of the tubers widely cultivated in Kalimantan with phytopharmacological potential, but its usage in traditional medicine is still limited. This study aims to ascertain the physiological and phytochemical characteristics of E. palmifolia following treatment with varying amounts of water and light intensity. The study used a completely randomized design (CRD) with two components: the treatment of light intensity 50% and 100% and water availability at 50%, 75%, and 100% concentrations, to create six treatment combinations. Flowering pace, leaf number, breadth, length, and blossom number were measured once every three days for one month. Wet weight, dry weight, stomata index, chlorophyll, carotene, vitamin C, flavonoids, and shoot ratio were assessed at harvest. The data were analyzed using ANOVA (Analysis of Variant). If there was a significant difference, a further test was carried out with the Duncan Multiple Range Test with a test level of 5%. The treatment effect on water availability of 75% and light intensity of 50% (K75I50) was significantly different and gave the highest value on leaf width of 0.28 cm, stomata index of 36.84 cm, carotenoid content of 39.70 g/ mL in E. palmifolia. The given treatments were not significantly different in the number of leaves, leaf length, the number of flowers, wet weight, dry weight, chlorophyll, vitamin C, flavonoids, and shoot ratio of Dayak roots. Water availability and 100% light intensity (K100I100) are the optimal treatments to accelerate the flowering of Dayak onion plants with a yield of 26.00 days.

“…Studi (M. N. I. Khan and Kabir, 2017) menunjukkan bahwa stress nanungan menyebabkna luas permukaan daun lebih besar dan daunnya lebih tipis dengan klorofil yang banyak namun pada Zea mays kondisi tercekam intensitas cahaya rendah disertai kekeringan menyebabkan kadar klorofil juga berkurang sehingga produktivitas menurun (Akmalia, Hafidha Asni;E. Suharyanto, 2017).…”

“…Pada akhirnya hal ini dapat menyebabkan perubahan penampakan daun dan mempengaruhi afinitasnya pada air. Sementara itu, naungan menyebabkan daun lebih tebal, indeks stomata menurun dan berkas pengangkut lebih berkembang pada Rhododenron agastum (Zhou et al, 2017) namun tidak pada Plectranthus amboinicus (Ekawati and Aziz, 2016) dan Zea mays (Akmalia and Suharyanto, 2017) yang menunjukkan bahwa daun lebih tipis dan berkas pengangkut kurang berkembang. Pada studi (Gupta et al, 2016), polusi di kota besar juga menyebabkan kerusakan sel penjaga, epidermis, dan mengubah bukaan stomata secara signifikan dan menurunkan ukuran juga densitas stomata (Lamalakshmi Devi et al, 2017).…”

Adaptasi dilakukan oleh tumbuhan demi kelangsungan hidupnya di lingkungan yang sangat dinamis. Salah satu jenis adaptasi yang dikembangkan adalah adaptasi anatomis pada akar, batang, maupun daun. Tujuan review artikel ini yakni memberikan langkah yang dapat dilakukan manusia dalam membantu tumbuhan untuk menjaga adaptasi anatomisnya sehingga dapat mendorong pertumbuhan dan perkembangan tumbuhan di bawah stress lingkungan. Review ini didasarkan pada telaah pustaka pada artikel-artikel ilmiah yang membahas tentang adaptasi anatomis tumbuhan terhadap perbedaan stress lingkungan. Berdasarkan kajian yang dilakukan, perlu adanya upaya penelitian lebih lanjut guna menjaga tumbuhan tetap lestari di bawah stress lingkungan yang semakin menantang. Kata kunci: adaptasi; anatomi; stress lingkungan
