“…Nevertheless, even with the reduction in germination by the toxic effect of aluminum, this was superior to 25%, and it can be considered elevated for a weed plant, demonstrating the capacity of adaptation of this to that adverse conditions (Zhao et al 2017). Similar results were observed in Conyza bonariensis and C. canadenses, when the seeds were put to germinate in moistened substrate with solutions of aluminum from zero to two cmolc L -1 , occurring reduction of germination in concentrations superior to 1.5 cmolc L -1 (Yamashita & Guimarã es, 2011 (Gallon, 2015), Jatropha curcas (Machado et al 2015) and Hancornia speciosa (Rodrigues et al 2017).…”

The objetive of this study was to identify the effects of aluminum concentrations and pH levels of solution on germination of Echium plantagineum L. seeds. Three different experiments were carried out in completely randomized design with four repetitions. In the first experiment, we used aluminum sulfate solutions in concentrations of 0.0; 0.3; 0.6; 1.0; 2.0; 3.0; 4.0; 5.0; 6.0 and 7.0 cmolc L -1 and in the second experiment, solutions with different pH, 3.0; 4.0; 5.0; 6.0; 7.0; 8.0; 9.0 and 10.0. In the third experiment, we carried out a factorial (4x4) with aluminum sulfate solutions (0.0; 2.0; 4.0 and 6.0 cmolc L -1 ) and pH (4.0; 5.0; 6.0 and 7.0). It was evaluated the germination of Echium plantagineum L. at four and 14 days after seeding (DAS), germination speed index, primary root length, aerial part and dry mass of seedlings. The presence of aluminum reduced the germination by 27 and 40% at four and 14 DAS, respectively, in concentrations superior to 3.0 cmolc L -1 . The three growth parameters presented linear reduction with the increase of aluminum concentrations. In the second experiment, the solutions with pH of 3.0 and 10.0 provided increases in germination, length of root and aerial part, and little influence in the dry mass of seedlings. In the third experiment, there was significant interaction between the aluminum concentrations and pH levels of substrate. The presence of aluminum in the substrate presented toxic effect on germination of seeds, length of seedlings and dry mass. The pH of the solution has little effect in germination of seeds and in the growth of seedlings of E. plantagineum.

“…Aluminum stress negatively affected seed germination and seedling vigor of Arctium lappa L. (Silverio et al, 2021). Machado et al (2015), when evaluating the germination of Jatropha curcas L. seeds exposed to five concentrations of Al, found that the element reduced germination by up to 90%, in addition to reducing 76 and 83% of the length and dry matter of the roots of the seedlings., respectively. In the literature, authors observed that some species also had root growth inhibition in response to Al toxicity, as in Phaseolus vulgaris L. (Domingues et al, 2013), Trifolium pretense L. (Scheffer-Basso and Prior, 2015) and Lactuca sativa L. (Silva and Matos, 2016).…”

The varieties creole are traditionally grown plant, adapted in places where the crops are developed and present in seeds banks of many famers. Thus the objective of this study was to investigate the performance of the germination process and possible toxic effects. Were used seeds of creole cultivars of beans (Phaseolus vulgaris L.), using different concentrations of aluminum. We used a randomized completely design with four repetitions of 25 seeds and the treatments were distributed in 4 x 5 factorial scheme, consisting of four bean cultivars (Carioca, Butter, Black, Red) and five concentrations (0.0, 2.5, 5.0, 7.5, and 10.0 mg L-1) of aluminum sulfate. The characteristics analyzed were percentage of germination, percentage of abnormal seedlings, germination speed index, root length, length of the base of the seedling to the hypocotyl, hypocotyl length of seedlings to the epicotyl, root dry mass and shoot dry mass. The variables germination percentage and germination speed index were not affected by the toxic effect of aluminum. The variables percentage of abnormal seedlings, root length and shoot showed a significant reduction with the increase in aluminum sulfate concentrations, thus showing a greater correlation between them.

“…Semakin tinggi konsentrasi ion Al dalam tanah maka semakin rendah pH tanah (Salam, 2012), Pada pH tanah rendah sekitar 4,3 bentuk Al yang melimpah adalah aluminium trivalent (Al 3+ ) dan sangat berdampak negatif terhadap pertumbuhan tanaman (Bojorquez- Quintal et al, 2017). Machado et al (2015) Berdasarkan hasil penelitian, perlakuan Al pH 4,5 pada perkecambahan memberikan respons paling buruk terhadap vialbilitas dan vigor tujuh varietas benih kedelai. Hal ini ditunjukkan dari muncul radikula pertama pada hari ke-1 media Al pH 4,5 sebesar 78,57% dibandingkan Al pH 6-7 sebesar 85,90% dan kontrol 90,76%.…”

Benih kedelai peka terhadap lingkungan masam sehingga perlu dilakukan evaluasi pada media masam untuk mengetahui varietas benih yang toleran terhadap kondisi tersebut. Tujuan penelitian ini untuk mengetahui pengaruh kondisi pH media tumbuh serta respons tujuh varietas benih kedelai terhadap viabilitas dan vigor. Penelitian ini merupakan percobaan faktorial dalam Rancangan Kelompok Teracak Sempurna (RKTS). Faktor pertama adalah tujuh varietas kedelai yaitu Anjasmoro, Grobogan, Detap 1, Derap 1, Deja 1, Dega 1 dan Dena 1. Faktor kedua adalah tiga taraf pH pada larutan Al yaitu tanpa Al pH 7, larutan dengan konsentrasi AlCl3.6H2O 1 mM pH 6 – 7, dan larutan dengan konsentrasi AlCl3.6H2O 1 mM pH 4,5. Sehingga terdapat 21 perlakuan yang diulang tiga kali. Perbedaan antar perlakuan menggunakan Uji Lanjut Beda Nyata Terkecil (BNT) pada taraf nyata 5%. Hasil penelitian didapatkan bahwa media tanpa Al memiliki viabilitas dan vigor terbaik diikuti media Al pH 6 – 7 dan media Al pH 4,5. Varietas dengan vigor dan viabilitas terbaik diperoleh pada varietas Dega 1 tercermin dari variabel muncul radikula, daya berkecambah, indeks vigor, bobot kering tajuk dan akar, serta panjang akar. Viabilitas dan vigor benih kedelai tergantung dari varietas kedelai dan taraf pH media tumbuh.ABSTRACTSoybean seeds are sensitive to soil acidic environments so it is necessary to study effect of acidic media to determine varieties that are tolerant to acidic conditions. The study purposed to determine the effect of different pH conditions both without and with Al on the viability and vigor of different varieties of soybean seeds. This research was a factorial experiment in a Completely Randomized Block Design (RCBD). The first factor was seven soybean varieties, namely Anjasmoro, Grobogan, Detap 1, Derap 1, Deja 1, Dega 1, and Dena 1. The second factor was three pH levels in Al solution, namely without Al pH 7, solution with AlCl3.6H2O pH 6—7, and solution with AlCl3.6H2O pH 4.5. There were 21 treatments with three replications. The differences between treatments were analyzed using the Least Significant Difference (LSD) at a 5%. The results showed that media without Al had the best viability and vigor followed by Al pH 6—7 media and Al pH 4.5 media. Varieties with the best vigor and viability were obtained in the Dega 1 variety as reflected in the variables of radicle emergence, germination, vigor index, hypocotil, and root dry weight, and root length. Viability and vigor of soybean seeds depended on soybean varieties and the pH level of the growing media.
