“…This compound can also affect stomata, as shown in a study conducted by Mulyono et al (2022) on induced hybrid maize lines (Zea mays L.), where it caused lower stomatal density but larger stomatal size. Similar results were also obtained in a study by de Oliveira Neves et al (2022) on olive trees (Olea europaea L.). Detecting plant mutations using the phenotypic method has been reported to face several limitations (Garcia et al 2016).…”

Abstract. Fathurrahman F, Ulpah S, Sodiq NAM, Mahadi I, 2024. The effect of Colchicine treatment on phenotype and genotype characteristics of Detam-2 variety of soybean Glycine max. Biodiversitas 25: 1230-1238. The enhancement of soybean plant mutagenesis to obtain phenotypic and genotypic diversity is essential in agriculture. This study aimed to analyze the effect of colchicine concentration on phenotypic and genotypic characteristics based on RAPD markers of detam-2 variety. The experiments were carried out from January to June 2023 in the experimental farm of the Agriculture Faculty, Universitas Islam Riau, Pekanbaru, Indonesia. Therefore, 600 plants were used, consisting of 200 controls and 400 samples treated with 3,500 ppm of colchicine. The growth parameter was analyzed using a DMRT statistical test at p<0.05, and stomata densities were compared using T-test. The mutant-1 produced the highest yield, a total of 235 pods (with 233 phity pods), seed weighed 93.20 g, which was significantly different from those of controls. Mutant-2 produced the highest dry weight of 100 seeds, which was 12.80 g, with a dry seed weight per plant of 63.30 g. Leaf types in mutant samples varied, including normal, purple leaf stems, and curly leaves. The genotypic study showed that primer OPAA-01 produced a different number of DNA bands. The highest genetic similarity was 0.961 among the controls, while the lowest was 0.451 between mutant-1 and the controls. Based on the results, the dendrogram produced two groups: control and mutant-1.

“…The residue left by the herbicide in the soil implies a toxicity in the plant, in this way, the action of high concentrations results in injuries and leaf necrosis, this phenomenon reflects negatively on the development of the plant, due to the impairment in the multiplication of its cells and also in their differentiation in the stomatal complex, starting to reflect in the number of stomata and this negative response in their functionality was also expected . Studies show that the high correlation between stomatal density and plant dry mass, as reported by Neves et al, (2022), may have compromised CO2 fixation in peanut dry mass.…”

Peanut has been used as an alternative in crop rotation in large areas of sugarcane. Plants may be subject to residual herbicides in these commercial areas as 2,4D and Picloram are applied for weed control. The objective of this research was to know the initial development of peanut seedlings grown in soil with herbicide residue. The experiment was carried out in August 2022, at Faculdades Integradas Stella Maris (FISMA), located in the Municipality of Andradina, State of São Paulo. The design was completely randomized (DIC), with five doses of the commercial product Dontor® (Picloram Acid and 2,4D Acid) as follows: absence; 1.0; 2.0; 4.0 and 8.0 L ha-1 and with four replications, totaling 20 plots or pots. The maximum point in the peanut response was at the dose of 5.0 liters per hectare of the herbicide 2,4D + Picloram. A dose greater than 5.00 liters per hectare of the herbicide 2,4D + Picloram compromises the development of peanuts. Leaf area and stomatal density responded in a negative linear fashion to herbicide doses.

“…Plants may change stomatal density when they are under nutritional restriction (Mirjalili et al, 2022;Wang et al, 2018), with water restriction (Hao et al, 2019); salt stress (Pompelli et al, 2021) and even species and varieties (Neves et al, 2022). in greater productivity.…”

Some production environments may present low pH and high levels of Al3+, thus making this element a limiting factor in the productivity of the cotton crop, which makes it necessary to use agricultural gypsum as a soil conditioner and even shell dust as sources low-cost alternatives to improve soil chemical attributes. The objective of this work was to know the responses of the use of alternative soil conditioners with aluminum in the cotton crop. The experiment was carried out in August 2022, at Faculdades Integradas Stella Maris (FISMA). The design was completely randomized, with six treatments, namely: no use of soil conditioners, agricultural gypsum (3.0 t ha-1); golden mussel shell powder (3.0 t ha-1); snail powder (3.0 t ha-1); agricultural gypsum (1.5 t ha-1) with golden mussel shell powder (1.5 t ha-1) and agricultural gypsum (1.5 t ha-1) with snail powder (1.5 t ha-1) and with four replications, totaling 24 plots or pots. The use of agricultural gypsum at a dose of 1.5 t ha-1 associated with golden mussel shell powder at a dose of 1.5 t ha-1 showed better responses in cotton development. The use of agricultural gypsum at a dose of 1.5 t ha-1 associated with golden mussel shell powder at a dose of 1.5 t ha-1 improves soil conditions for cultivation. The pyrolysis method at high temperatures to break the crystalline structures of mollusc shells was efficient.
