PENGARUH EKSTRAK ETANOL DAUN TAPAK DARA (Catharanthus roseus L.) DAN KOLKISIN TERHADAP PERKECAMBAHAN BIJI CABAI RAWIT HIBRIDA (Capsicum annuum)

Abstract

Catharanthus roseus L. contain vinca alkaloid compounds which have anti-mitotic effect like colchicine. The application of Catharanthus roseus L. extract and colchicine in many plants was usually done by soaking the plant seeds. The aim of this research was to analyze the effect of ethanolic leaf extract of Catharanthus roseus L. and colchicine on seed germination of Capsicum annuum. 20 Seeds of Capsicum annuum were soaked for 24 h in ethanolic leaf extract of Catharanthus roseus L. (0,05%, 0,1% dan 0,5%), colchicine (0,05%, 0,1% dan 0,5%) and water as control. Seed germination percentage was observed and plant height was measured after 30 days. The 0,5% leaf extract and 0,5% colchicine caused the lowest germination percentage. The 0,5% leaf extract caused the lowest average plant height. Based on ANOVA and Tukey's HSD test, soaked in 0,5% ethanol leaf extract treatment was significantly different with other treatments (signification 95%)

Bio-Catharantin Effects on Phenotypic Traits and Chromosome Number of Shallots (Allium Cepa L. Var. Ascalonicum 'Tajuk')

“…With depolymerization, the spindle thread formation is inhibited. Consequently, the chromosomes fail to divide during mitosis but continue to multiply (Purbosari and Puspitasari, 2018). Therefore, it is a polyploidization process.…”

Vinca alkaloids effects on the morphological characters of Canavalia ensiformis

“…These alkaloids have a colchicine-like effect that can duplicate chromosomes. They act by preventing tubulin polymerization, so that the separation of chromosome sets is disrupted when mitosis and cells have multiplied the chromosomes (Purbosari and Etika, 2018). Currently, the antimitotic compounds vincristine and vinblastine are available in the form of pure compounds and are produced commercially (Daryono, 2015).…”

“…There have been numerous studies conducted on vinca alkaloids-induced polyploidy in order to improve the characters and yields of plants. Soybean (Kusnuriyanti et al, 2017), melon (Daryono et al, 2018), cayenne pepper (Purbosari and Etika, 2018), lily (Wardana et al, 2019), and spearmint (Viza, 2019) showed significant increase in several characteristics such as plant height, leaf area, fruit size, and seed weight. Therefore, the present study was carried out to investigate the mutagenic effect of vinca alkaloids on morphological traits in jack beans.…”
