“…Selain dengan menutup stomata, tumbuhan juga akan menggugurkan daun dan memperkecil luas daunnya untuk mengurangi kehilangan air melalui transpirasi (Lambers et al, 1998). Luas daun tanaman jarak pagar (Lapanjang et al, 2008), jati (Hendrati et al, 2016), dan mangga (Helaly et al, 2017) menurun secara signifikan pada kondisi cekaman kekeringan. Skirycz & Inze (2010) melaporkan bahwa cekaman kekeringan menurunkan pertumbuhan daun tanaman dengan cara memengaruhi pembelahan dan pembesaran sel, sehingga luas daun tanaman menurun karena menurunnya jumlah dan ukuran sel.…”

Kebutuhan kayu jati (Tectona grandis L.f.) untuk industri nasional hanya bisa dipenuhi sekitar 0,75 juta m 3 /tahun dari 2,5 juta m 3 /tahun yang diantaranya disebabkan oleh umur panen pohon jati yang lama dan semakin berkurangnya lahan yang sesuai dengan habitat jati akibat perubahan iklim. Indonesia memiliki lahan kering yang cukup luas untuk pengembangan jati, sehingga dibutuhkan bibit tanaman jati yang bisa tumbuh cepat dan tahan dengan kondisi kekeringan. Penelitian ini bertujuan untuk membandingkan sifat ketahanan klon jati tetraploid dengan diploid terhadap cekaman kekeringan. Penelitian dilakukan dengan Rancangan Acak Kelompok (RAK) yang disusun secara faktorial dengan ulangan sebanyak 9 kali di rumah kaca. Faktor pertama adalah klon diploid (2x) dan tetraploid (4x). Faktor kedua adalah tingkat cekaman kekeringan meliputi interval penyiraman 3 hari, 7 hari, 14 hari, 21 hari, dan disiram hanya di awal perlakuan. Pengamatan dilakukan terhadap tinggi bibit, diameter batang, jumlah daun, luas daun, ketebalan daun, potensial air daun, stomata, perakaran, dan bobot kering tanaman. Hasil penelitian menunjukkan bahwa pertumbuhan kedua klon bibit jati menurun dalam kondisi cekaman kekeringan, namun pertumbuhan bibit tetraploid lebih baik dibandingkan dengan bibit diploidnya.

“…One of the plant responses to drought stress is to reduce leaf area. The decrease in leaf area is related to transpiration which will decrease in rate so that the plants do not lose too much water (Hendrati et al 2016). According to Hidayati et al (2017), plants that lack water will inhibit the growth and development of young leaves, cell shrinkage occurs, and the leaf aging process is followed by the dropping of old leaves, resulting in a reduction in the photosynthetic area.…”

Induction of drought resistance in bell pepper (Capsicum annuum var. grossum) with osmopriming Polyethylene Glycol (PEG) 4000

Abstract. Prellia A, Solichatun, Pitoyo A. 2023. Induction of drought resistance in bell pepper (Capsicum annuum var. grossum) with osmopriming Polyethylene Glycol (PEG) 4000. Asian J Agric 7: 34-46. The bell pepper (C. annuum var. grossum) is an economically valuable chili cultivar. However, in Indonesia, the cultivation of bell peppers is hampered by drought stress. Osmopriming is an alternative method to improve seed quality. That method was used by soaking the seeds in osmoticum solutions, with Polyethylene Glycol (PEG) as the solution. This research examines the effect of osmopriming with PEG 4000 on the germination and growth of bell pepper seedlings under various drought stressors. In 2020, seeds were collected from ripe bell peppers grown by farmers in Surjo Hamlet, Sukabumi Village, Cepogo Sub-district, Boyolali District, Central Java, Indonesia. This study employed a Completely Randomized Design (CRD) with two parameters: PEG concentration and water capacity variations. The concentrations of PEG 4000 utilized were 0, 50, 100, and 150 g/L. The drought stress test is conducted by cultivating primed bell pepper seedlings in planting media with varying water capacities of 100%, 75%, and 50% Space Capacity (SC). Included in the drought group with a moderate stress level is a water capacity of 50% SC. Each treatment was replicated three times. Under drought stress, osmopriming with PEG 4000 accelerated the germination rate and affected seedling growth regarding height, number of leaves, leaf area, wet seedling weight, and shoot-root ratio. However, under drought stress, osmopriming PEG 4000 had no significant effect on the rise in proline and chlorophyll content nor on the decrease in carotenoids and nitrate reductase activity. PEG 150 g/L with 50% SC was ideal for seedling height, leaf number, leaf area, and wet weight, while PEG 100 g/L with 100% SC was optimal for the shoot-root ratio.

“…Plants have adaptive mechanisms to abiotic stress, there was accumulated amino acid for keeping the turgor. Hendrati et al (2016) stated that plants have strategies to defend themselves to keep growing, including avoidance, osmotic adjustment, and salt excretion. Based on this experiment, results showed that Dendang planted on 50 cm of sunken-bed had the higher proline content compared to Dendang planted on 25 cm of sunken-bed.…”

Abstract. Nasrudin, Kurniasih B. 2021. The agro-physiological characteristics of three rice varieties affected by water depth in the coastal agricultural land of Yogyakarta, Indonesia. Biodiversitas 22: 3656-3662. Coastal agricultural land has many obstacles of abiotic stress for plant cultivation, including waterlogging, strong wind, and high salt concentration. Therefore, the use of adaptive rice varieties, as well as good land management, are expected to be a solution for rice cultivation in the coastal agricultural land. The objective of this study was to examine the agro-physiological characteristics of three rice varieties planted in coastal agricultural land which were affected by water salinity up to more than 10 dS m-1. This study was conducted from February to July 2017 at Tirtohargo, Bantul District, Special Region of Yogyakarta. The experiment was arranged in a split-plot design, with the depths of sunken-bed as a main plot consisted of 25 cm and 50 cm, and variety as a subplot consisted of IR 64, Inpara 4, and Dendang. The experiment results showed that Dendang had the highest growth and yield in coastal agricultural land compared to Inpara 4 and IR64. The highest value is indicated in plant height, leaf area, proline content, and productivity. The depths 50 cm of sunken-bed increased leaf area and proline content, whereas the depths of 25 cm sunken-bed increased productivity. Dendang showed better agro-physiological activity and had the highest productivity. The depths of 50 cm increased several parameters in agro-physiological characteristics, however, the depths of 25 cm increased grain yield. Among the varieties tested, in salinity, the highest growth and yield variables were shown by Dendang, followed by IR 64 and Inpara 4.
