Influence of Terminal Bud Pinching On Growth and Yield of Chrysanthemum, Chrysanthemum Indicum L.

Abstract

An experiment on pinching (viz. P 0 ; without pinching and P 1 ; with pinching) with 3 replications showed the tallest (37.7 cm) and the shortest plant (33.4 cm) without pinching and with pinching, respectively. Maximum number of leaves (30.1) and flowers (58.7) per plant were recorded following pinching (P 1 ); and minimum number of leaves (26.8) and flowers (37.9) per plant were from without pinching (P 0 ).Key words: Pinching, Chrysanthemum indicum, Flower, Terminal bud, Growth, Yield Chrysanthemum (Chrysanthemum indicum L.) is a popular flower plant, belongs to Asteraceae. Chrysanthemum, commonly known as the Mum flower, is one of the most popular decorative flowers in the world. In recent years, demand for pot plants for house decoration and for use in amenity horticulture, in many countries in the world has steadily been increased for their outstanding aesthetic beauty, long lasting quality, and their good prospect of marketing as cut flowers and potted plants (Erler and Siegmund 1986). It is also very popular in floral bouquets and flower arrangements. A large number of chrysanthemum cultivars are the result of selection by growers and breeders in many centuries. The climatic condition of Bangladesh is well-adapted for cultivation of chrysanthemum but it's commercial production in Bangladesh is very low. It grows well in sandy loam soil with high light intensity.Pinching is removing the terminal growing portion of stem mainly for inducing branch and also to reduce the plant height. Pinching makes chrysanthemums compact, bushy plants, with more blooms. The plant height, stem diameter and number of inflorescences increase in the number of pruning's (Brum et al. 2007). In Bangladesh, only limited studies have been done on pinching for growth and yield of chrysanthemums. The present research work was undertaken to study the effects of pinching on growth and yield of chrysanthemum.The experiment was conducted at Horticulture Farm, Sher-e

Effects of Shoot Apex Removal on Growth and Yield Attributes of Cotton

“…Since hormone balance is presumably important to the overall effect on growth and morphological changes. By removing the shoot apex auxins concentration reduces that hampers upward plant growth and the lateral shoots trigger to grow as a result the number of branches as well as the number of leaves increased (Habiba et al, 2012). The current finding is also in line with those of Ali et al (2021), Ona et al (2015) and Sharaf-Eldien et al (2017), who documented that removal of the shoot apex in several ornamental plants increased the number of leaves plant -1 .…”

Managing the Growth and Flower Production of Zinnia (Zinnia elegans) through Benzyle Amino Purine (BAP) Application and Pinching

“…In case of controlled (un-treated) plants produced less number of leaves (54.8) plant -1 . Habiba et al (2012) observed more leaves plant -1 after pinching Chrysanthemum indicum. Naresh and Singh (2012) reported that plants (African marigold) that were pinched produced maximum leaves plant -1 .…”

“…Terminal buds producing natural auxin were removed which enhanced number of branches plant -1 in chrysanthemum flower. With removing the terminal buds reduces auxins concentration that hampers upward plant growth and the lateral buds starts to sprout as a result number of branches increases (Habiba et al, 2012). Eraki (1994) also found increased branches plant -1 with foliar application of BAP on Hibiscus.…”

Upaya Pencapaian Standar Snapdragon (Antirrhinum majus) Sebagai Tanaman Hias Pot Melalui Perlakuan Pinching dan Konsentrasi Paclobutrazol

“…Variabel jumlah bunga per tanaman pada perlakuan pinching (P1) menghasilkan jumlah bunga yang lebih banyak daripada perlakuan non pinching (P0). Penelitian Habiba et al (2012) pada tanaman krisan, bahwa tunas samping membantu dalam mencapai pertumbuhan vegetatif yang optimal tanpa mengganggu pertumbuhan tanaman krisan yang normal. Ini bisa menjadi hasil dari distribusi yang lebih merata dari asimilasi antara beberapa titik tumbuh (dalam cabang aksila) daripada hanya yang apikal (seperti pada tanaman kontrol).…”
