    Effect of polyploidy and pollination methods on capsule and seed set of pansies (Viola × wittrockiana Gams) by A.L. Dalbato, F. Kobza, L.M. Karlsson

    Published 2013-03-01
    “…Capsule set with open pollination was 32-64 %, with self-pollination by hand 18-49% and with cross-pollination by hand 14-43%, while no plant successfully set capsules with seeds under isolators if not pollinated manually. …”

    Genetic variability and selection criteria of some sunflower genotypes under different pollination methods by Mohamed Ali ABDELSATAR, Asmaa Abd EL-Halime AHMED, Suzan El-Latif Kamel IBRAHIM

    Published 2020-09-01
    “… To determinate self-compatible genotypes for increasing autogamy yielded, the ten sunflower genotypes were sown under four pollination methods i.e., open-, self-, hand- and sib-pollinations in a randomized complete block design replicated thrice at Kafr-El-Hamam Agricultural research Station, Sharkia Governorate, Agricultural Research Center, Egypt during 2018 and 2019 summer seasons. …”

    Autofocus Entropy Repositioning Method Bioinspired in the Magnetic Field Memory of the Bees Applied to Pollination by Daniel de Matos Luna dos Santos, Ewaldo Eder Carvalho Santana, Paulo Fernandes da Silva Junior, Jonathan Araujo Queiroz, João Viana da Fonseca Neto, Allan Kardec Barros, Carlos Augusto de Moraes Cruz, Viviane S. de Aquino, Luís S. O. de Castro, Raimundo Carlos Silvério Freire, Paulo Henrique da Fonseca Silva

    Published 2021-09-01
    “…In this paper, a bioinspired method in the magnetic field memory of the bees, applied in a rover of precision pollination, is presented. The method calculates sharpness features by entropy and variance of the Laplacian of images segmented by color in the HSV system in real-time. …”

    STUDIES ON COMPATIBILITY, FRUIT SET AND FRUIT QUALITY BY DIFFERENT POLLINATORS IN ANNA APPLE CULTIVAR by Mahmoud Maklad, Mai Anwar, نظمي عبد الغني, Nahla Awad

    Published 2020-12-01
    “…The pollen tube of E25 cultivar grew slowly with heavy deposition of calluses along to the tube where its growth stopped in the lower part of Anna style four days after pollination. Therefore, they need pollinizer cultivars as for good fruit set. …”
