“…Diameter Batang Mutan Tanaman Pemberian dosis sinar gamma berbeda tidak berpengaruh terhadap diameter tanaman, kecuali pada umur 1 minggu setelah tanam disajikan pada Tabel 2. Diameter batang tanaman lamtoro umur 18 MST pada level 100 gy memberikan pengaruh paling baik di bandingkan dengan level lainnya hal ini dikarenakan pemberian dosis rendah memberikan pengaruh pada metabolism tanaman Hal ini sesuai dengan pendapat Metwally et al (2015)…”

Forage is the main source of feed for ruminants. Forage consists of two types, namely grass and legumes. Leguminosa is a type of forage as a source of protein. One type of legume that is well known by breeders in Indonesia is lamtoro (Leucaena leucocephala cv. Tarramba). This study was aimed to produce candidate mutants of lamtoro drought resistant to acid stress conditions. The experiment in this study used an unbalanced completely randomized design with 6 treatments of 740 different replications based on different sources of lamtoro plant mutants at different levels (P0: 0 n= 89, P1: 100 gy n= 82, P2: 200 gy n= 153, P3:300 gy n=120, P4: 400 gy n= 244, P5: 500 gy n= 52). Variables observed included plant height, number of stalks, leaf loss and stem diameter. The results showed that lamtoro plants irradiated with gamma rays at a level of 200 gy-500 gy were significantly higher than 100 gy irradiation at 10 and 12 days watering, but the diameter of the plants was larger at 100 gy irradiation. It can be watering intervals of 10 days and 12 days on the parameters of height and stem diameter showed that gamma rays irradiation of 400 gy resulted in dry-resistant lamtoro mutant candidates under acid stress condition. Key words: gamma rays, lamtoro mutant, watering interval

“…Efek dari penyinaran tersebut mengakibatkan tanaman yang diberi perlakuan iradiasi akan berbeda dengan indukannya atau terbentuknya jenis baru (Suwarno et al, 2013). Metwally et al (2015) berpendapat bahwa efek dari radiasi menyebabkan perubahan dalam struktur seluler tanaman dan metabolisme tanaman seperti pelebaran membran tilakoid dan perubahan dalam fotosintesis.…”

The purpose of the research was to obtain the morphological variability of M1 sunflower ornamental plant and information of lethal doses (LD50) effect of mutation by gamma ray irradiation. The research was arranged in monofactor experimental with Completely Randomized Design (RAL) with 5 treatments and 5 replication, each replication consisted of 5 sunflower seeds was irradiated by gamma ray of 0, 5, 25, 45, and 65 Gy. The data observed were analyzed by anova and followed with BNT of 5% level. Parameters observed included germination, plant height, stem diameter, tube flower diameter, tape flower diameter, initiation time, perfect bloom age, chlorophyll, ribbon flower number, seed number, total seed weight, weight of 100 seeds, LD50, Flower color and heritability. The result showed that irradiation significant effected to plant height, stem diameter, tube flower diameter, ribbon flower diameter, initiation time, seeds number, seed weight, weight of 100 seeds. Lethal doses of sunflower is 74,19 Gy. Heritability value range from 23,47 to 73,81%.Keywords : Helianthus annus L., irradiation, LD50, heritability

“…Steroid sex hormones, e.g. progesterone, improve growth, cell division, and pollination of plants; additionally, they help to cope with salinity (Rojek et al, 2015;Genisel et al, 2013;Metwally et al, 2015). Xue et al (2017) reported that the application of Sabzmeydani et al-Salicylic acid and progesterone effect on Kentucky bluegrass progesterone under stressful conditions alleviated the impacts of oxidative stress, increased catalase, and reduced leaf proteins of wheat as compared to the plants subject to the stress but not treated with the hormone.…”

Salinity is one of the most important limiting factors in plant growth. It is also a predominant constraint that impairs grass growth and quality. Plant hormones play important roles in the capability of plants to adapt to environmental stresses. Hence, the impact of two plant growth regulators (PGRs) i.e. salicylic acid (SA) and progesterone (P4) was studied on biological characteristics of Poa pratensis in saline conditions in a greenhouse experimnt. The experimental treatments were composed of salinity at four levels (0, 2, 4, and 6 dS m-1) and six levels of PGRs (control, 1 mg L-1 P4,10 mg L-1 P4, 1 mM SA, 3 mM SA, and 1 mg L-1 P4 + 1 mM SA). The results showed that leaf firing percentage was increased with the excess in salinity, but the use of SA and P4 eased the effects of salinity stress and reduced leaf firing under salinity. 6 dS m-1 and 3 mM SA salinity caused to the maximum electrolyte leakage. The highest relative water content was observed in 4 dS m-1 salinity and 1 mM SA treatment. The highest glycine betaine was related to 6 dS m-1 NaCl and no hormone application. Salinity increased total protein and catalase, and the simultaneous use of P4 and SA exhibited the highest total protein and catalase content, whilst the control plants showed the lowest ones. The application of salinity stress reduced chlorophyll content, but SA and P4 increased it. The application of the two growth regulators improved carotenoid content under salinity stress. Overall, the results showed that the application of SA and P4 improved salinity tolerance and increased pigments and antioxidant enzyme activities.
