Leaf removal and cluster thinning trials in ‘Foglia Tonda’ grapevine
Acta Horticulturae, 2017The research was carried out in the 2015 growing season in order to optimize the qualitative expression of the native Tuscan cv. Foglia Tonda (Vitis vinifera). The effects of three different treatments for yield control in comparison with the untreated (CTRL) were analyzed: two intensity of early leaf removal achieved at the end of May (4 and 6 leaves ...

Oregon ‘Pinot noir’ grape anthocyanin enhancement by early leaf removal
Food Chemistry, 2013Complete cluster zone leaf removal of 'Pinot noir' was initiated at three separate pre-véraison growth stages (bloom, grain-pea size, and bunch closure) and maintained leaf free until harvest, for four growing seasons (2008-2011). Fruit anthocyanin composition was examined at harvest for the last two vintages (2010 and 2011) and compared to a control ...

Lead Ions Removal Using Pineapple Leaf-Based Modified Celluloses
Applied Science and Engineering Progress, 2022Pineapple leaves are largely discarded in the harvest area and considered as agricultural waste. Herein, the extracted pineapple leaves fiber was altered with chelating agents to become an adsorbent for lead ions (Pb2+) removal from aqueous solutions.

Plant Biology, 2015
AbstractPlant senescence is largely influenced by carbohydrate content. In order to investigate the impact of carbohydrate content on leaf senescence and photosystem II (PSII) during the senescence process, phloem girdling (PG), leaf removal (LR) and a combination of phloem girdling and leaf removal (GR) were performed on Alhagi sparsifolia (Fabaceae ...

Noise removal using statistical operators for efficient leaf identification
International Journal of Computer Aided Engineering and Technology, 2018Plant identification based on leaf shape is becoming a popular trend, since each leaf carries substantial information that can be used to identify plant. This is difficult because the features of a leaf shape can be influenced by other leaves that have similar features but different categories. This paper presents the most popular statistical operators:

Effects of Leaf Removal, Leaf Tying, and Overhead Irrigation on Transplanted Pygmy Date Palms
Arboriculture & Urban Forestry, 1994AbstractThe effects of leaf removal, leaf tying, and overhead irrigation during transplanting were determined using mature pygmy date palms(Phoenix roebelenii).In one experiment palms had all, 2/3, or none of their leaves removed and were irrigated overhead or on the soil surface only.

Vitis vinifera leaf litter for biosorptive removal of nitrophenols
International Journal of Environmental Science and Technology, 2017Vitis vinifera (grape) leaf litter, an abundant agricultural waste in South Africa was chemically modified with H3PO4 and carbonized for use as biosorbent. Characterization and the potential application of the adsorbent in simultaneous removal of 4-nitrophenol and 2-nitrophenol from aqueous solutions were investigated.

Impact of leaf removal on Istrian Malvasia wine quality
2018The aim of this study was to assess the impact of three different sunlight exposure conditions, obtained by hand and mechanical leaf removal at pea-size berry stage, on photosynthetic active radiation in the cluster zone, cluster temperature, on volatile aroma compounds, hydroxycinnamic acids and sensory characteristics of Istrian Malvasia (Vitis ...

Simulated Insect Damage to Rice: Effects of Leaf Removal
Journal of Economic Entomology, 1978Insect damage to rice was simulated by artificially removing various portions of the photosynthetic surfaces during the seedling and tillering stage of growth. Twenty-five and 50% leaf removal in the seedling stage reduced yields 3 and 8%. respectively. Twenty-five and 50% removal in the tillering stage reduced yields 5 and 12%. respectively.
