Evaluation of Difference Leaf Cutting Shape and Pruning Techniques on Root and Shoot Production of Labisia pumila

Labisia pumila or locally known as kacip fatimah, belongs to the family of Primulaceae. It possesses several medicinal properties such as pre and post-partum medication, anti-obesity, anti-aging and anti-microbial. In this paper, an attempt was made to discover the suitable leaf cutting shape and pruning technique to increase the yield and improve the quality of root and shoot production of L. pumila. Three different leaves cutting shape were tested (shape A, shape B and shape C) to study their effect on root production. The cuttings were distinguished by the shape of leaf midrib at the basal part. Whereas for pruning experiment, two pruning techniques were identified namely half cut and full cut. In half cut, the leaves petiole remained on the stem while in full cut, all leaves and petiole was removed from the stem. Leaf cutting from shape C rooted earlier (at week 5) than the others (at week 6). However, leaves cutting from shape A performed better in the number of root and root length. For pruning experiment, no significant difference was observed in the growth performance of L. pumila within the 12 weeks of observation. However, the full cut pruning technique produced new shoot earlier than half cut within the observation period.  An extended observation period is required to measure the growth and yield of this herbal plant. The output of this study will benefit the industries for a quick and effective method in order to produce mass planting materials for the species

Evaluation of genotype x environment interaction on morphological characteristics of eight selected Labisia pumila var. alata clones (Kacip Fatimah) by Francis and Kannenbergs method

Since Labisia pumila species are not yet produce locally, it is important for this species to undergo propagation and testing at different environment in different location so that only variety or clones that has good mean plant growth over a wide range of environments can be identified as well as introduced to Malaysia farmer. In other means, the selected clones of L. pumila produced are genetically superior and genetically stable. The aim of this study is to evaluate interaction of genotype x environment between eight selected Labisia pumila var. alata clones and to identify stability of these eight clones respected to plant growth characteristics; plant height, leaf number, leaf length, leaf width, and collar region. Eight clones (KF01, KF02, KF03, KF04, KF05, KF06, KF07 and KF08) had tested at four different locations of FRIM Research Station; SPF Mata Ayer, Perlis; SPF Maran, Pahang; SPF Setiu, Terengganu; and FRIM Kepong, Selangor. The experimental unit consisted of 3 blocks, 0.7 m between clone and 0.4 m within rows in randomized complete block design (RCBD) at area of 0.04 ha under a drip irrigation system. Clones main effect from ANOVA analysis was found in give highly contribution for the phenotypic expression of this species at each locations. Across locations, highly significant was found for clone and location / (GXE) effects. The interaction existed raised the need to use stabilityanalysis by Francis and Kannenberg’s method to predict the stability. Results scattergram from Francis and Kannenberg’s method showed that clones KF07 and KF08 were shows its superiority in growth performances as both present in Group I. Thus, both were selected as potential elite planting materials as they considered stable and perform well in various range of environments at four locations trial

Genotype Screening and Propagation Techniques of Three Selected Medicinal Plant Species for Production of High-Quality Planting Material

Medicinal plants are a vital source of new bioactive compounds due to their ecological biodiversity and varied chemical properties of each species. Phenotypic selection coupled with the evaluation of genotypes based on the chemical profile can be used for the development of a high-yielding variety. However, most of the raw material that has been used for commercial production of herbal products is mainly derived from wild sources, with little knowledge of the quality of genetic materials. Thus, three medicinal species, Chromolaena odorata (Siam weed), Andrographis paniculata (Creat), and Baeckea frutescens (False ru), were chosen based on their significant benefits to human health. These medicinal species have been traditionally used to treat various illnesses, and have been shown to possess anti-inflammatory, antimicrobial, anticancer, and antioxidant properties. This paper highlights the harvesting method and collection of accessions from natural habitats for the selection of superior genotypes. Individual plants having superior phenotypic characteristics and bioactive compounds were identified. We successfully developed appropriate propagation techniques for each species for the mass production of high-yielding planting material. The establishment of breeding activities for these medicinal plants will provide quality raw materials to support the herbal industry in increasing the value of pharmaceutical products. These efforts will also ensure the sustainable production of high-quality planting materials for the establishment of herbal plantations
