“…Hormetic effects of ionizing radiation were observed in various cell types of humans, animals, plants and fungi correspondingly causing increased cellular survival, as well as acceleration of growth and development (Lehrer & Rosenzweig, 2015; Tugay, Zhdanova, Zheltonozhsky, Sadovnikov, & Dighton, 2006). For example, germination and growth of seeds from diverse plant species are stimulated through IR‐doses below 15 Gy whereas increased exposures have inhibitory effects (Nayak, Patil, Behera, & Jadeja, 2015; Thapa, 2004; Zanzibar & Sudrajat, 2016). Specifically, stimulatory IR‐effects are still controversially discussed in the radiation biology community to date.…”

Research concerning the effects of ionizing radiation (IR) on plant systems is essential for numerous aspects of human society, as for instance, in terms of agriculture and plant breeding, but additionally for elucidating consequences of radioactive contamination of the ecosphere. This comprehensive survey analyses effects of x‐ and γ‐irradiation on male gametophytes comprising primarily in vitro but also in vivo data of diverse plant species. The IR‐dose range for pollen performance was compiled and 50% inhibition doses (ID50) for germination and tube growth were comparatively related to physiological characteristics of the microgametophyte. Factors influencing IR‐susceptibility of mature pollen and polarized tube growth were evaluated, such as dose‐rate, environmental conditions, or species‐related variations. In addition, all available reports suggesting bio‐positive IR‐effects particularly on pollen performance were examined. Most importantly, for the first time influences of IR specifically on diverse phylogenetic models of polar cell growth were comparatively analysed, and thus demonstrated that the gametophytic system of pollen is extremely resistant to IR, more than plant sporophytes and especially much more than comparable animal cells. Beyond that, this study develops hypotheses regarding a molecular basis for the extreme IR‐resistance of the plant microgametophyte and highlights its unique rank among organismal systems.

“…Similar result reported by Suhartanto et al (2018) that dose of 40 Gy was able to improve seed vigor and seedling growth so that it can be applied to increase vigor of Neolamarckia cadamba seeds. As in the Magnolia champaca, irradiation using 10 Gy of the stored seeds will increase the germination capacity by 34.1% of the control (Zanzibar and Sudrajat 2016). Seeds with stronger dormancy such as Falcataria moluccana require higher doses to increase low seed viability and vigor, as reported by Yulianti et al (2016) who were able to increase seed germination from 40% to 80% with gamma ray irradiation at a dose of 60 Gy.…”

“…Seed navigation is a treatment carried out to improve the physiology and biochemistry of seeds related to synchronization, speed, and an increased ability of seeds to germinate (Sutariati et al 2014). One of the invigoration methods used is low gammaray irradiation doses (Piri et al 2011, Iglesias-Andreu et al 2012, Zanzibar et al 2015, Zanzibar and Sudrajat, 2016.…”

Deteriorated seeds can be improved by invigoration treatment, including gamma-ray irradiation by . The purpose of this study was to determine the proper dose of gamma-ray irradiation ( 60 Co) to increase the decreased vigor of suren (Toona sureni (Blume) Merr.) seeds. This study uses a factorial completely randomized design (CRD) with aging and irradiation as the treatments. Aging factors consisted of 0, 2, and 4 days. Irradiation factor consisted of 7 levels, namely 0, 5, 10, 20, 40, 80, and 100 Gy, repeated four times. The parameters observed were the electrical conductivity, germination percentage, germination speed, and seedling height. The results showed that Seed aging treatment significantly affected Suren seed germination with 75% (2 days aging) and 56% (4 days aging) germination. The 40 Gy dose of gamma-ray irradiation could increase germination percentage and germination speed of low suren seed vigor increasing 51.42% and 60.21%, respectively. Simultaneously, the cell membrane damage of stored suren increased with gamma-ray irradiation treatment of more than 40 Gy based on electrical conductivity. In seeds with high germination, such as seeds without aging and seed aging for two days with a germination percentage of 80% and 75%, respectively, the invigoration treatment was not effective. Invigoration treatment was effective in increasing the deteriorated or low viability and vigor of the suren seeds.

ABSTRACT. Sengon (Albizia falcataria) ABSTRAK.Sengon (Albizia falcataria) merupakan salah satu jenis andalan di hutan rakyat, pada umumnya jenis ini ditanam menggunakan system agroforestry. Permasalahan pada tanaman sengon saat ini adalah banyaknya hama dan penyakit yang menyerang tegakan sengon, sehingga mengakibatkan menurunnya produktivitas. Peningkatan produktivitas dapat diupayakan sejak dari tingkat benih yaitu melalui peningkatan viabilitas dan vigor benih. Pemanfaatan teknik irradiasi sinar gamma digunakan sebagai seed treatment untuk meningkatkan vigor dan kualitas benih sudah banyak dilakukan pada benih tanaman pertanian, namun pada benih tanaman hutan masih terbatas. Tujuan dari penelitian ini adalah mengetahui efektivitas penerapan teknik irradiasi sinar gamma untuk meningkatkan viabilitas benih sengon. Rancangan penelitian yang digunakan adalah Rancangan Faktorial dalam Acak Lengkap, terdiri dari 2 faktor, yaitu asal benih dan faktor lainnya adalah dosis radiasi. Hasil penelitian menunjukkan bahwa asal benih dan dosis sinar gamma berpengaruh nyata terhadap daya berkecambah dan kecepatan berkecambah benih sengon. Secara umum menunjukkan adanya peningkatan dalam perkecambahan yaitu daya berkecambah (DB) dan kecepatan berkecambah (KCT) akibat pemberian perlakuan irradiasi dengan sinar gamma. Peningkatan DB dan KCT mulai terlhat pada dosis 5 Gy, dan terus meningkat hingga dosis 90 Gy. Daya Berkecambah benih meningkat antara 13,5 % -50,9 % dari kontrol. Hal ini berarti teknik irradiasi sinar gamma pada dosis rendah dapat digunakan utnuk meningkatkan viabilitas dan vigor benih sengon. Kata kunci : Albizia
