Multiplikasi In Vitro Stroberi Kultivar Tochiotome Dengan Penambahan Jenis Dan Konsentrasi Sitokinin Untuk Perbanyakan Bibit, Ega Raisya, Denny Sobardini Sobarna, Anne Nuraini, Syariful Mubarok, Erni Suminar, Masako Akutsu

Jurnal Kultivasi

Perbanyakan tanaman stroberi secara konvensional dilakukan dengan menggunakan stolon, tetapi kurang efektif serta kualitas bibit yang dihasilkan kurang baik akibat adanya akumulasi penyakit. Budidaya stroberi memerlukan adanya perbanyakan bibit secara massal, tetapi tidak mengubah kualitasnya. Multiplikasi in vitro menjadi solusi untuk penyediaan bibit berkualitas dalam jumlah besar. Upaya untuk mendapatkan tunas in vitro dalam jumlah banyak yakni perlu adanya penambahan zat pengatur tumbuh golongan sitokinin seperti Benzylaminopurine (BAP) atau Thidiazuron (TDZ). Tujuan penelitian ini adalah mengetahui dan menetapkan jenis serta konsentrasi sitokinin dengan hasil terbaik dalam multiplikasi stroberi kultivar Tochiotome. Percobaan dilaksanakan di Laboratorium Kultur Jaringan Tanaman, Teknologi Benih, Fakultas …

Estimation Of Additive And Dominance Effects Of A Mutant Glutathione S-Transferase Gene On Anthocyanin And Proanthocyanidin Content In Muscadine Grape (Vitis Rotundifolia), Autumn Brown

Horticulture Undergraduate Honors Theses

The skin color of muscadine grapes (Vitis rotundifolia) is typically classified as black or bronze. A glutathione S-transferase, VrunGST4, has been identified as a candidate gene for berry skin color in muscadine grapes. A molecular marker was developed within VrunGST4 to distinguish between muscadine genotypes (cultivars and selections) with bronze (T:T), heterozygote black (C:T), and homozygote black (C:C) berries. The objectives of this study were to determine whether there was a correlation between berry skin color and total anthocyanin content and to calculate additive and dominance effects of VrunGST4 in determining total anthocyanins in the berries and …

Fruit Tree Responses To Water Stress: Automated Physiological Measurements And Rootstock Responses, William D. Wheeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

New orchard plantings utilize trees grafted to dwarfing rootstocks planted close together to facilitate larger harvests. These dwarfing rootstocks have not been comprehensively studied for their ability to withstand drought. This is of special importance in the Intermountain West which has limited rainfall. Additionally, orchard growers face competition for water from a growing population and increased uncertainty in rainfall from climate change. My research examined the use of dendrometers, which measure changes in trunk diameter, and sap flow sensors, which measure how quickly sap moves, as methods to inform growers about tree water status. I also used a weighing lysimeter …

Comparison Of A T-Trellis And A Rotating Cross-Arm Trellis For Arkansas Blackberry Production, Erika Henderson

Graduate Theses and Dissertations

As blackberry production in the southeastern United States expands, the need for updated cultural practices, like alternative trellis systems that enhance blackberry fruit yield, fruit quality, and economic viability for fresh-market growers are needed. There are challenges to producing high-quality blackberry fruit with high yields in the Southeast due to intense heat, high rainfall, humidity, and heavy pest pressure. Southeastern growers are interested in the rotating cross-arm (RCA) trellis due to its potential to increase yield and fruit quality, however there is minimal research of its use in blackberry production in the Southeast. In 2019 and 2020, a trial was …

Citrus Pruning, Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

Pruning is the cultural practice involving the removal of tree branches and limbs designed to enhance the performance and productivity of trees.

Ideally this is best done after harvest to prevent unwanted fruit loss. With citrus, correct pruning can improve yields, fruit quality, and make managing trees easier.

Stimulan merupakan teknologi yang digunakan untuk meningkatkan produksi lateks. Penggunaan stimulan sintetik yang berlebih dapat menurunkan produksi sehingga perlu dicoba stimulant organik. Penelitian ini bertujuan untuk mengetahui respons produksi tanaman karet klon BPM 24 terhadap aplikasi stimulan organik kulit pisang. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Karet Sembawa, Palembang, Sumatera Selatan dari September sampai November 2019. Metode percobaan menggunakan Rancangan Acak Kelompok dengan 11 perlakuan stimulan dan 5 ulangan. Pengamatan dilakukan terhadap …

Phenotypic And Genotypic Studies In The Peach [Prunus Persica (L.) Batsch] And Muscadine Grape (Vitis Rotundifolia Michx.), Jennifer Anne Lewter

Graduate Theses and Dissertations

Peach: Peaches [Prunus persica (L.) Batsch] are routinely chilled to increase shelf-life. Exposure to temperatures of 5° C for two weeks can induce chilling injury (CI) symptoms, including flesh mealiness (or wooliness) and a lack of juiciness. Phenotypic data were collected on seven biparental F1 peach populations maintained at the University of Arkansas Fruit Research Station. A genome wide association study (GWAS) was performed using TASSEL 5 which identified four quantitative trait loci (QTLs) associated with expressible juice, four QTLs for mealiness, five QTLs for soluble solids, and three QTLs for fruit weight. Exploiting these genetic markers could help breeders …

Projected Surface Water For Fruit And Vegetable Irrigation Under A Changing Climate In The Us, Marty Matlock, Greg Thoma, Kieu Ngoc Le, Eric Cummings, Zach Morgan, Andrew Shaw

Water Systems

Increasing greenhouse gas concentrations in the atmosphere, resulting in climate impacts, are raising concerns over the hydrologic cycle and its effects upon agricultural productivity. If rainfall patterns change, meeting an increased demand for fruits and vegetables will pose a challenge for domestic production regions in the United States (U.S.). Information on potential water supply scarcity in the current production regions provides decision makers with critical information for risk mitigation for future production. We used a hydrologic balance-based model of historic and future water availability to evaluate risk of available irrigation water to support major fruit and vegetable production the US. …

Morphological And Agronomic Variability Among Cultivars, Landraces, And Genebank Accessions Of Purple Passion Fruit, Passiflora Edulis F. Edulis, Nohra Rodríguez Castillo, Daniel Ambachew, Luz Marina Melgarejo, Matthew Wohlgemuth Blair

Agricultural and Environmental Sciences Faculty Research

Global demand for juice of the purple passion fruit, Passiflora edulis f. edulis, is growing, making it a promising species for farmers to grow in the highland tropics, to which it is adapted. However, research centers and private companies have done little to produce new high-yielding varieties. The objective of the present study, therefore, was to evaluate the agronomic and morphological characteristics of 50 passion fruit genotypes across two different elevations and agro-ecological sites as a base for germplasm enhancement. Three groups of genotypes were commercial cultivars (8 genotypes), genebank accessions (8), and landraces (34) collected from throughout the …

Determining Cluster Thinning And Storage Effects On Fruit Quality And Marketability Attributes Of Arkansas Table Grapes Grown Under High Tunnel Systems., Virginia Beasley

Graduate Theses and Dissertations

Table Grapes (Vitus vinifera) are highly valued horticulture crops world-wide. Often, table grape production in the southern United States is restricted due to climate and pest issues. Viticulture production could be expanded to this region by the use of controlled environment growing systems, such as high tunnels (HT). The objective of this project was to evaluate the effectiveness of HT systems for grape cultivation and compare the effects of different cluster thinning treatments on vines. In this two-year study, the cultivars Faith, Gratitude, Hope, and Jupiter were grown in HT systems and assessed for postharvest qualities at harvest and during …
