“…Waterlogging causes the root to be in a hypoxia environment, and inhibited the growth of root (Brisson, 2002;Hank, 2006). Recent studies found that waterlogging stress resulted in a reduction in the dry matter of roots of wheat and bean seedings, the growth of crops was found to be negatively by waterlogging (Pedo et al 2018;Velasco et al 2019). In this experiment, waterlogged waxy corn nearisogenic lines showed significant changes in root fresh and dry weight compared with the controls (Table.1).…”

“…newly emerged adventitious roots can at least partially compensate for growth inhibition or even death in the distal part of the root system during waterlogging, but not completely compensate for loss of root dry mass (Malik et al 2003;Colmer et al 2011;Juan et al 2020). Recent studies found that waterlogging stress resulted in a reduction in the dry matter of roots of wheat and bean seedings, the growth of crops was found to be negatively by waterlogging (Pedo et al 2018;Velasco et al 2019). Root morphological and anatomical characteristics determine root growth and function in anoxic waterlogged soils (Yamauchi et al 2018).…”

Waterlogging stress is one of the most natural stress, which due to excessive rainfall or low-lying terrain, and limits crop growth and yield. Our objective was to study the morpho-anatomical and physiological characteristics of a paired near-isogenic lines of waxy corn under waterlogging stress. This experiment was implemented in pots with a paired of near-isogenic lines differing in waterlogging tolerance: Zz-R (waterlogging-resistant) and Zz-S (waterlogging-sensitive). Root morphology features, anaerobic respiratory enzyme activity, and tissue anatomical characteristics were measured at 0, 2, 4, 6 and 8d in the control and waterlogging conditions. The result indicated that waterlogging induced a decrease in the root length, volume and surface areas of the two waxy corn inbred lines, the total root length, root volume, and root surface area of the Zz-R showed less reduction than the Zz-S. Waterlogging stress influenced significantly by the parenchyma cells in cortex of root between Zz-R and Zz-S. Zz-R can also maintain a higher level of anaerobic respiratory enzyme activity under waterlogging stress. The different reaction between the paired near-isogenic lines may be responsible for higher tolerance of Zz-R than Zz-S. These results can provide a certain theoretical basis of the resistance evaluation and breeding to the resistant varieties.

“…Nascimento et al (2009) found similar results, where sanding scarification resulted in a higher dry mass of Parkia platycephala seedlings, and higher averages in immersion treatments in sulfuric acid for 30 and 45 minutes. According to Pedó et al (2018), there is a direct relation between average dry matter weights and seedlings vigour. Therefore, T3 to T7 treatments promoted greater vigour potential and seedling uniformity.…”

Superação de dormência em sementes de <i>Tachigali micropetala</i> (Ducke) Zarucchi & Pipoly (Fabaceae – Caesalpinioideae)

O uso de espécies florestais na produção de mudas tem sido intensificado devido à necessidade de recuperação de áreas desmatadas e produção de biomassa. No entanto, a domesticação de espécies florestais nativas é restrita devido à falta de estudos relacionados à ecologia, fisiologia e morfologia de suas sementes. A espécie Tachigali micropetala (Ducke) Zarucchi & Pipoly, pertencente à família Fabaceae, apresenta dormência de tegumento que dificulta a entrada de água e, consequentemente, a germinação. O objetivo deste trabalho foi selecionar os melhores tratamentos para a quebra da dormência em sementes de T. micropetala. Os tratamentos foram: controle (sem tratamento pré-germinativo), desponte, escarificação em lixa, imersão em ácido sulfúrico por 5, 10, 15 e 20 minutos e imersão em água a 80 ° C por 20 minutos. A semeadura foi realizada em papel germiteste e o delineamento estatístico utilizado foi o inteiramente casualizado com oito tratamentos, cinco repetições de 25 sementes. Para o teste de sanidade, as sementes foram submetidas a dois tipos de tratamentos: assepsia com 1,5% de hipoclorito de sódio e controle (sementes sem assepsia). Cada tratamento continha 10 repetições, com 20 sementes cada. Os resultados obtidos mostram que os tratamentos em ácido por 15 e 10 minutos e a escarificação mecânica com lixa apresentaram 90,4%, 85,6% e 83,2% de germinação, respectivamente, sendo estes os mais eficientes para superar a dormência em sementes de T. micropetala.

“…While leaf length and leaf width showed significantly different results, where the comparison genotype Balebat (13.76 cm) showed the highest leaf length followed by the Gada, F1374003, F 1074005, and F1074003 genotype, leaf width of the comparison genotype Balebat (5.27 cm) had the highest leaf width compared to other genotypes and followed by genotypes F1074003, F1374003, Gada. The width of the canopy is an important character of the photosynthesis rate, which indirectly affects plant production (Pedo et al, 2013). Harvest period showed the same thing, where the comparison genotypes dominated the fastest harvesting ages, namely Elegant (70.00 DAT), CH3, Gada (71.00 DAT) followed by the test genotypes, namely F1074003 (72.00 DAT), F1374005, F1374003 (73.00 DAT).…”

One of the important stages in chili breeding is the multi-location test. The lowlands became one agroecology in the chili multi-location test because most farmers, especially in Sumatra, plant chilies on the lowlands after the rice planting season. The purpose of this study was to understand the qualitative and quantitative characteristics of chili genotypes in a lowland area. The experiment was arranged in a single-factor randomized complete block design (RCBD) with three replications. The chili genotypes evaluated were four test lines and six check varieties. The quantitative data were statistically analyzed using analysis of variance (ANOVA) followed by evaluation of genotype means using the least significant difference (LSD) tests by SPSS Statistics software. The results showed that the check variety having the lowest productivity was CH3 (1.19 tons ha-1) and the highest was Elegant (4.55 tons ha-1). The productivity of four genotypes from IPB were significantly different from the CH3 and Imperial 10 varieties, but not significantly different from Baja (2.96 tons ha-1), Balebat (3.87 tons ha-1), Elegant (4.55 tons ha-1) and Gada (3.04 tons ha-1) varieties. This research shows that the four genotypes from IPB have the potential to become new superior varieties. Keywords: Lampung; multi-location; plant breeding; varieties
