“…Trifoliata and both hybrids TSKC × CTSW-041 and TSKC × CTSW-025 did not differ statistically from each other; they had the highest seedling emergence (Table 2). Passos et al (2006), Oliveira and Scivittaro (2007) and Sarmiento et al (2016) found lower percentages of seedling emergence for the rootstock Trifoliata, i.e., 81%, 84.4% and 80%, respectively.…”

“…The citrumelo 'Swingle' usually has low values of seedling emergence. It was observed by several studies, such as the ones conducted by Teixeira et al (2009), Rodrigues et al (2015) and Sarmiento et al (2016), who found 51%, 79% and 65%, it means that more seeds need to be sown per tube, with the purpose of avoiding losses in the next stages of seedling production, due to the low emergence percentage of the rootstock seeds. MXWL-mandarin orange tree 'Willow Leaf' (C. deliciosa Tenore); LHA-orange tree 'Hamlin' (C. sinensis); CLEO-tangerine tree 'Cleópatra' (C. reshni hort.…”

“…It should also be taken into account that citrus seedlings are the main input to establish an orchard and that a phytosanitary approach is important because of the wide variety of diseases and plagues that affect citriculture. Therefore, it is important to yield seedlings in certified nurseries, i.e., in a protected environment named screened nursery (Oliveira et al, 2008;Sarmiento et al, 2016;Parolin et al, 2017).…”

The fact that Brazilian citriculture has focused on few rootstocks poses several phytosanitary risks to the culture and has made genetic improvement programs develop hybrid genotypes to be used as novel alternatives. This study aimed at evaluating the behavior of 42 different rootstocks regarding their emergence percentage and speed in weather conditions experienced in the extreme south of Brazil. Seeds of hybrids developed by the Citrus Genetic Improvement Program (PMG Citros) at the Embrapa Mandioca e Fruticultura (PMG Citros) and cultivars from other citrus growing regions were sown in conical tubes filled with commercial substrate in May 2017. A thoroughly randomized design with 4 replicates, each composed of 45 sampling units, was employed. Emergence percentage and emergence speed of every genotype were evaluated and the ones with the highest emergence percentage of seedlings and the ones with the most precocious emergence were identified. All genotypes completed seedling emergence 98 days after sowing. Seeds of Trifoliata, TSKC × CTSW-041 and TSKC × CTSW-025 had the highest values of seedling emergence whereas the highest emergence speed indexes were exhibited by genotypes Trifoliata and lemon tree ‘Cravo’.

“…Use of on paper is more economical when compared to between paper, so the use of the first substrate is indicated. This was also used to evaluate germination of citrus rootstock cultivars (SARMIENTO et al, 2016). The best germination performance in paper substrate can be attributed to the vegetative structure's development lower physical impairment and higher aeration of this substrate in comparison to sand (MACHADO et al, 2019).…”

Morphology of seeds and seedlings, and substrates in germination of Citrus limetta

et al. 2022

This research studied the morphology of seeds and seedlings, in addition to obtaining information about the type and time of germination of sweet lemon seeds in five substrates (on blotting paper, between blotting paper, on washed sterilized sand, between washed sterilized sand and in paper roll). C. limetta seeds were measured, and external description was performed. Afterwards, sown in the sand and kept at 25 ºC to monitoring germination and morphological description of the resulting seedlings. A second experiment was evaluated for substrate efficiency: paper roll, on and between paper, on and between sand in the germination of C. limetta seeds. Speed index, average time and relative frequency of germination were evaluated. In addition, date of the first and last germination count was established. Treatment averages were compared using the Tukey test at 5% probability. C. limetta seeds are ovoid, slightly wrinkled and polyembryonic. Germination is hypogeal, cryptocotylar or phanerocotylar. The seedlings have leathery eophylls with simple leaves, elliptical shape or close to the elliptical, tending to ovate. It has a pivoting root system that is colored yellow to cream with the presence of secondary roots. The average germination time is between 18 and 22 days. The substrate indicated for seed germination is on paper.

“…Ormosia, a intensidade da dormência das sementes é variável e o método adequado pode ser distinto para cada espécie.O índice de velocidade de germinação não diferiu entre os diferentes tempos de imersão em ácido sulfúrico, com valores superiores à escarifi cação com lixa e à testemunha (Figura 1A). SegundoSarmiento et al (2016), o IVG permite quantifi car vigor das sementes, pois quanto maior o IVG, menor o número de dias para ocorrência da germinação. Neste sentido, todos os tratamentos com ácido sulfúrico apresentaram maior efi ciência quando comparados ao uso da lixa, provavelmente por agir na superfície do tegumento de forma mais homogênea, enquanto a lixa normalmente rompe o tegumento apenas em uma região o que deve ter atrasado a embebição das sementes, ocasionando maior tempo para início da germinação.…”
