The paclobutrazol application and pinching technique on Lisianthus plants (Eustoma grandiflorum)

Abstract

The research concerns on the paclobutrazol application and the pinching technique on Lisianthus plants (Eustoma grandiflorum). This research aimed to determine the appropriate time to apply the paclobutrazol and pinching technique suitable for Lisianthus potted plants. This study was carried out using factorial experiments consisting of two factors, arranged in Randomized Complete Block Design. The first factor was the time of application of paclobutrazol that consist of A0 (Without paclobutrazol application), A1 (Application of paclobutrazol 6 days after planting), A2 (Application of paclobutrazol 12 days after planting), A3 (Application of paclobutrazol 18 days after planting). The second factor of technique pinching was P0 (Without pinching), P1 (Single pinching technique), P2 (1½ pinching technique), P3 (Double pinching technique). The data were analyzed using analysis of variance at the 5% level and mean separations with Duncan’s Multiple Range Test. The results showed that the application of paclobutrazol and pinching technique could shorten Lisianthus plants. The application of paclobutrazol decreased the number of flowers per plant and shortened the flower stalks. The pinching technique increases the number of branches, number of internodes, number of nodes, number of flowers per plant. The application of paclobutrazol 18 days after planting and double pinching techniques were able to shorten the height of lisianthus plants with dense branching and many flowers.

The effect of the drug Zircon on the decorative qualities of large-flowered eustoma plants in pot

“…The data in Table 1 indicate that the growth regulator Zircon introduction when growing the seedlings of the studied eustoma hybrids is effective. Of the concentrations recommended by literary sources used on different plants [10,12,15,16], a 2.5% solution of the drug proved more effective for eustoma. Plants of this variant of the experiment had higher biometric indicators characterizing the qualitative characteristics of seedlings, exceeding the indicators of the control variant of the experiment by 10.0-46.8%.…”

“…Thanks to breeders, a large number of varieties and hybrids of new series of largeflowered eustoma enter the world market every year, characterized by beautiful coloring, flower shape, flowering time, resistance to diseases and pests [16,17].…”

Pengaruh Berbagai Konsentrasi Eco Enzyme dan Pinching Terhadap Pertumbuhan dan Pembungaan Tanaman Pacar Air (Impatiens hawkeri Bull) Pada Vertical Pipe

“…Hormon auksin dapat bekerja sama dengan hormon giberelin dalam proses pembelahan sel yang menghasilkan tunas lateral baru (Zamzani et al, 2015). Pembesaran sel terjadi akibat pengaruh dua hormon yang (Widyastuti, 2020).…”

“…Panjang dari tunas baru dapat menentukan jumlah ruas pada tunas. Semakin panjang dan banyak tunas lateral baru dapat meningkatkan jumlah ruas sehingga dapat berpengaruh pada pertumbuhan daun yang lebih banyak(Widyastuti, 2020).Aplikasi eco enzyme pada konsentrasi 10 ml.l -1 dengan double pinching didapatkan hasil luas daun yang lebih tinggi dan berbeda nyata dibandingkan dengan semua perlakuan (Gambar 3). Pertumbuhan daun yang diakibatkan oleh kandungan nitrogen yaitu penambahan lebar daun dan jumlah daun(Sarido dan Junia, 2017).…”
