Pollen quality in Zea mays as a prerequisite for sperm cell isolation and pollen transformation


, : Pollen quality in Zea mays as a prerequisite for sperm cell isolation and pollen transformation. Plant sperm cells as tools for biotechnology: 97-104

Among 11 hybrids, water content of pollen at anthesis varied between 55 and 60%. In hybrid ROC, germination of pollen grains in vitro increased initially with aging (caused by dehydration) but subsequently fell sharply. Grain set after pollination with dehydrated pollen of several genotypes was constant until the pollen water content fell below 15%, where it became a function of pollen water content.

Mass isolation of viable sperm cells from maize pollen was further studied to increase the yield of sperm cells. Four different approaches on pollen bursting and sperm collection were tried. Results showed that pollen bursting rate could reach as...
