“…These results suggest that BRRI dhan71 is the most drought tolerant among the varieties. These results are consistent with those of other studies that have reported that high concentration of PEG reduce the final germination percentages of rice (Islam et al, 2018;Purbajanti et al, 2019). Seeds of all the varieties treated with 25% PEG did not germinate, which indicated that 25% PEG was the lowest osmotic potential for rice seed germination (Fig.…”

Drought is one of the major stress factors affecting the growth and development of plants, and is responsible for considerable crop yield losses worldwide. An experiment was conducted to compare three rice (Oryza sativa L.) varieties (BRRI dhan49, BRRI dhan71 and BRRI dhan75) for drought tolerance based on some growth parameters and physiological status in germination stage. Drought stress was imposed by five levels of polyethylene glycol (PEG) (0%, 10%, 15%, 20% and 25%). Rice varieties showed good germination with PEG concentration up to 15%. At 20% PEG concentration, a sharp reduction in germination percentage was observed and the highest germination percentage (55.53%) was found in the variety BRRI dhan71. Seeds of all the varieties treated with 25% PEG did not germinate. Seedling growth in terms of plumule and radicle length, fresh weight and dry weight decreased with increasing drought stress in all the varieties. Among the varieties, BRRI dhan71 was found to be the best at 20% PEG for seedling growth. Drought stress treatments decreased seedling length and weight vigor index in rice, whereas the highest seedling length and weight vigor index were obtained from BRRI dhan71. Accumulation of proline increased along with the increase of PEG concentration. The highest proline accumulation (3.08 mmol g-1 leaf) was obtained from the BRRI dhan71 at the higher treatment (20% PEG). This result suggests that BRRI dhan71 showed best performance under drought stress because of its own nature of tolerance. SAARC J. Agric., 20(1): 107-119 (2022)

“…Water stress weakens seed germination (Swain et al 2014) and the height of the seedling (Sokoto and Muhammad 2014). The higher concentration of PEG 6000 lowers growth value, emergence value, germination energy, and the relative germination value on all rice cultivars (Purbajanti et al 2019). The length of the main root in the first three youngest roots related to phytomers (Pr1-Pr3) was increased in Binadhan-11 and reduced in Binadhan-7, as long as BRRI 71 was under 5% PEG treatment, compared to control.…”

“…The solution of PEG 6000 at a concentration 5-20% for in vitro has been reported to inhibit the osmotic potential with soil conditions in the field capacity of some plants, such as wheat (Öztürk et al 2016;Faisal et al 2019), barley (Mapikasari et al 2017;Hellal et al 2018), rice (Nazirah et al 2015;Abiri et al 2016;Widyastuti et al 2016;Akbar et al 2018;Purbajanti et al 2019), soybean (Savitri 2010;Zuyasna et al 2016), eggplant (Sinaga et al 2015), plantain (Irawan et al 2015). A few studies report the application of PEG 6000 on the rubber plant.…”

Abstract. Pasaribu SA, Basyuni M, Purba E, Hasanah Y. 2021. Drought tolerance selection of GT1 rubber seedlings with the addition of polyethylene glycol (PEG) 6000. Biodiversitas 22: 394-400. Tolerance of the rootstock of rubber to drought stress is not optimal. The root system can therefore be used as an indicator of drought tolerance to inhibit the growth of the plant. A good root system of rubber rootstocks is thought to help the plants acquire greater resistance to drought stress. Polyethylene glycol 6000 osmotic solution controls the water potential in the growing medium. This study aimed to analyze the effect of PEG 6000 osmotic solution (0%; 7.5%; and 15% concentration) on rubber seedlings leading to the development of morphological characters and sensitivity index. GT1 (Gondang Tapen 1) rubber seeds to be used as planting material were collected from the seed source garden of PT Socfin Indonesia. The study was carried out from January to February 2019, using a non-factorial randomized block design. The morphological characters observed were tapped root length, shoot height, the increased rate of taproot length, shoot height increase rate, ratio of taproot length, and shoot height. Data were analyzed using analysis of variance, discriminant, and drought stress sensitivity index. The results showed that the addition of PEG 6000 in planting media in vitro significantly influenced the character of the rate of increase of taproot length. The sensitivity index of taproot increase rate and the ratio of taproot length and shoot height was moderate at 7.5% levely contrast, the addition of PEG 6000 in planting media in vitro did not significantly impact it. The present study suggested that the rate of increase of taproot length was a distinguishing character showing the initial tolerance level of the GT1 seedlings to drought.

“…Penggunaan PEG (Poly Ethylene Glycol) dengan bobot molekul 6000 telah banyak digunakan pada penelitian pengaruh cekaman air terhadap pertumbuhan tanaman (Verslues et al, 2006, Purbajanti et al, 2018, Sawitri et al, 2018. Hal tersebut karena pada konsentrasi tertentu PEG 6000 dapat memberikan kondisi kekeringan seperti pada lahan kering (Mirbahar et al, 2013).…”

Perkecambahan benih merupakan salah satu tahapan paling kritis dalam pertumbuhan tanaman. Penapisan di tahap ini dapat menjadi informasi awal terhadap toleransi kekeringan. Tujuan penelitian ini adalah mengevaluasi toleransi kekeringan pada padi lokal Lampung varietas Lumbung Sewu Cantik pada fase perkecambahan. Penelitian ini menggunakan Rancangan Acak Lengkap dengan tiga konsentrasi PEG dengan tiga ulangan. Konsentrasi PEG yang diberikan yaitu 0%, 10% dan 20%. Data hasil pengamatan dianalisis ragam pada taraf a uji = 0.05 dan analisis lanjut menggunakan uji Duncan’s Multiple Range Test (DMRT). Hasil pengamatan menunjukkan bahwa semakin tinggi konsentrasi PEG membuat panjang plumulae dan panjang akar seminal padi semakin menurun. Namun, pada radikula, pemberian PEG 20% tidak menurunkan pertumbuhan panjang. Pemberian PEG dengan konsentrasi 20% juga tidak membuat berat kering radikula menurun dan pada akar seminal juga tidak ada perbedaan berat yang signifikan antara pemberian PEG konsentrasi 10% dan 20%. Hal ini menunjukkan bahwa Padi Lumbung Sewu Cantik memiliki potensi toleran terhadap kekeringan pada fase perkecambahan.
