Evolutionary of Pollen Ornamentation in Ornamental Crabapples
2019Pollen ornamentation patterns are important in the study of plant genetic evolution and systematic taxonomy. However, they are normally difficult to quantify. Based on observations of pollen exine ornamentation characteristics of 128 flowering crabapple germplasms (44 natural species and 84 cultivars), three qualitative variables with binary properties

Polyphenol intermediates accumulate predominantly in peripheral parts of floral tissues and play various roles in tissue homeostasis. A limited ornamental flower shelf life is caused by early tissue senescence, otherwise known as programmed cell death (PCD), which is characterized by processes such as DNA degradation, reduction in protein content and ...

Pollen Morphological Characteristics of Ornamental Crabapples
2019In order to understand the basic characteristics of Malus pollen, 107 Malus germplasm pollen samples were observed by a field-emission scanning electron microscope. The results showed that: Malus pollens belonged to the N3P4C5 type, were all bilaterally symmetrical, with perprolate, prolate, or sub-rectangular shapes in equatorial view, and tricolpate ...

Evolutionary Law for Ornamental Crabapple Pollen Traits
2019Nine phenotypic traits were assessed by field emission electron microscopy to explore pollen variation in various Malus species and cultivars. Phylogenetic reconstruction showed that the resulting molecular tree coincided with classical taxonomy. No distinct pollen evolutionary pattern was observed in Malus spp., except for exine ornamentation, which ...

SUMMARYCrabapple (Malus spp.) trees are wild relatives of apple trees and have become increasingly important as an ornamental plant germplasm resource. To establish an efficient regeneration system from leaves would be valuable for the rapid propagation of ornamental crabapple. We therefore evaluated the effects of the type and concentration of various
