Carbohydrate content and season collection of cuttings from ‘Roxo de Valinhos’ fig tree

Abstract

Choosing the best season collection of cuttings is essential to have success with propagation, due mainly to carbohydrate content, since is a source of energy for roots and shoots development. In literature, there are no papers that associate the collection season of cuttings with carbohydrate contents in figs. Therefore, the current study aimed to evaluate carbohydrate contents and season collection of cuttings to propagate ‘Roxo de Valinhos’ fig tree. The experiment was conducted in a greenhouse; cuttings were collected in the first week of the following months: June, July, August and September. The design was in completely randomized blocks, with four replicates of 30 cuttings collected per season. The following traits were evaluated: carbohydrate content; percentage of root cuttings, bud cuttings, cuttings without bud and root; number of buds, leaves and roots per cutting; length of the largest root and bud; bud diameter; bud and root dry mass; and root volume. Results indicated high carbohydrate content in cuttings that were collected in August; therefore, the best month to collect cuttings of ‘Roxo de Valinhos’ fig tree in the city of São Manuel, state of São Paulo. This result is due to high percentage of rooted cuttings and better development. Furthermore, carbohydrate content mainly affects root growth; besides that, reducing sugars are the most important feature in the development of cuttings.

Estado da arte da propagação vegetativa por estaquia de espécies arbustivo-arbóreas

“…Utilizando Ficus carica, tanto Souza et al (2019) quanto Nava et al (2014) obtiveram melhores resultados no inverno. Vale destacar que Nava et al (2014) compararam dois meses de inverno e, mesmo assim, obtiveram diferenças entre os dois momentos de instalação.…”

Response of growth and yield of Salibu rice on the stem cutting height of parent crops after harvest

“…On stem cutting of 0 and 5 cm indicated that most of the shoots emerged from the base of the stem and subsequently formed new tillers. According to Souza et al [14], carbohydrate content in stems mainly affected root growth. He et al [15], stated that the ratoon rice yield depends on the panicle growing from the stem of the parent crops.…”

Studi Komposisi Media Tumbuh dan Bahan Setek Pada Produksi Benih Klonal Kopi Robusta

“…Bahkan di Madagaskar terbukti bahwa setek kopi tanpa daun menurut Costle dikutip Gerbaba (2012) tidak mampu bertunas dan berakar. Hal ini berkaitan dengan fungsi daun sebagai sarana untuk memproduksi fotosintat (karbohidrat) sebagai sumber energi seperti yang dikemukakan oleh Tombesi et al (2015), Marler (2018), dan Souza et al (2019). Hasil penelitian lain pada setek tanaman vanili menunjukkan bahwa semakin banyak jumlah buku pada setek, maka semakin tinggi persentase tunas yang terbentuk (Mesay et al, 2015).…”
