Abstract

Most farmers determine the cutting of air layer seed in a corp through the amount of the growing roots from air layer itself. The roots can be an indicator of air layer cutting method in a corp. The roots, which are too old or too young, grow less optimal in the air layer seed after being transferred into another cultivated medium. It is necessary to have knowledge about the precise age of air layer cutting so that the vegetative propagation by using air layer can be performed accurately and efficiently. The treatment that is executed is the age of air layer and the corps accession. The result of this research indicates that the effect of the difference air layer age on plant growth is at the age of emerging buds, aged 180 Day is treated with the age of the fastest emerging shoots. The growth of Bojonegoro air layer plants results that does not differ with Wonogiri air layer plants. There is no interaction between air layer age with sapodilla accession on plant growth.

Abstract

Black rice Cempo Ireng is a local variety with a long plant life, high plant posture, and low productivity. Plant breeding by gamma irradiation was carried out to correct these weaknesses. The results of the gamma irradiation process included a selection process for each generation and produced potential lines numbers such as 8, 51, and 52. The characterization was based on the NDUS (Novelty, Distinctiveness, Uniformity, and Stability) test. The purpose of this study was to characterize potential lines as one of the requirements for the release of plant varieties. The study was conducted in the paddy fields of Pakahan Village, Jogonalan District, Klaten Regency, from February-July 2022. The method used was a single factor randomized complete block design with three replications. Data were analyzed by T test with 5% level. The results of the study showed that the three potential lines have differences with the parent and the Sembada varieties. Three potential lines can be deemed to be new, dictinct, uniform, and stable.

Abstract

Pineapple (Ananas comosus) is a popular fruit crop in Indonesia. Pineapple crowns are one of the planting materials used in pineapple cultivation, but their growth is slower than other planting materials, so that the addition of chitosan is needed, which has the potential to stimulate growth. This study aims to determine the best concentration and application time of chitosan that can improve pineapple growth. The study was conducted in the screenhouse of the Faculty of Agriculture, Sebelas Maret University, Surakarta during March-June 2025 with a Completely Randomized Design (CRD) with two factors, namely chitosan concentration (without chitosan, 1 ppm, 3 ppm, 5 ppm) and time of chitosan application (morning, afternoon, morning and afternoon). Each treatment was repeated 4 times, resulting in 48 experimental units. The results showed that no combination of concentration and time of chitosan application was found to simultaneously increase pineapple growth. The treatment concentration of 1 ppm and 3 ppm gave the best result to increasing leaf number; concentration 1 ppm, 3 ppm, and 5 ppm gave the best result to increasing total leaf area and longest root length. Time of chitosan application once in the morning or evening gave the best result to increasing photosynthesis rate and stomatal conductance. Chitosan has the potential as a biostimulant for plant growth and is effective in increasing the physiological activity of plants.

Abstract

This research aims to obtain morphological character of Matoa (Pometia pinnata JR Forst & G Forst) plant. This research had been conducted from April to October 2021, in 5 Regency (Karanganyar, Klaten, Pati, Sukoharjo, and Surakarta) Central Java. The morphological characther based on direct observation through primary and secondary data recording, and documenting parts of an adult matoa plant with purposive random sampling. Data of morphological characterization of matoa was analyzed using descriptive analysis method with assistance of Ntsys v2.02i program. The results showed a morphological diversity of matoa plant accessions. Fifty (50) matoa accessions exhibit morphological diversity in plant height, canopy diameter, stem circumference, branching type, leaf colour, number of leaflets, compound leaf length, compound leaf petiole length, leaflet width, fruit density, fruit length, fruit weight, seed weight, and fruit skin colour.
