Evaluating Self-Pollination Methods: Their Impact on Nut Set and Nutlet Abscission in Macadamia [PDF]
Nut set is an important determinant of yield and plays a pivotal role in orchard profitability. The complex process of nut setting is governed by numerous factors, with pollination being a critical mechanism.

Evolution of floral scent in relation to self-incompatibility and capacity for autonomous self-pollination in the perennial herb Arabis alpina. [PDF]
Background and Aims The transition from outcrossing to selfing is a frequent evolutionary shift in flowering plants and is predicted to result in reduced allocation to pollinator attraction if plants can self-pollinate autonomously.

Precocious genotypes and homozygous tendency generated by self-pollination in walnut. [PDF]
Observations of precocious (early bearing) genotypes of walnut (Juglans regia L.) under natural conditions encouraged us to study the origin and genetic control of these fascinating traits.

Continued Self-pollination in Cotton [PDF]
IN NATURE of Sept. 1, 1928, p. 314, Mr. G. L. Kottur distinguishes between “the deterioration of a selection due to selfing” and “the hybrid vigour of the F1 plants”. Surely, on whatever theory we interpret hybrid vigour, both phenomena are manifestations of it.

The peach is though considered to be a self fertile fruit species, also some self sterile and male sterile varieties have been registered. The latter type seems to be frequently met in Asian varieties, whereas in the USA and Europe, J. H.

Experimental analysis of mating patterns in a clonal plant reveals contrasting modes of self-pollination. [PDF]
Hermaphrodite plants commonly practice self‐fertilization (selfing), but the mechanisms responsible vary depending on the mode of self‐pollination, pollinator behavior, and degree of clonality. Whether selfing occurs within (autogamy) or between flowers (

Background : Variation in style length has been reported in Senecio vulgaris and has been associated with outcrossing rate. Aims : To determine if (i) long styles lack germinated pollen on stigmas left to self-pollinate, (ii) successful self-pollination ...

Floral mechanisms promote pollination success and reduce the incidence of self‐pollination in a fly‐pollinated self‐incompatible orchid [PDF]
Among flowering plants, self‐incompatibility is considered the most efficient system for avoiding self‐fertilization. However, many self‐incompatible plants have also evolved floral mechanisms to reduce sexual conflict.

The Evolution of Self-Pollination in Clarkia xantiana [PDF]
The evolutionary effects of outbreeding and inbreeding systems have caused considerable interest and speculation over the years and their influence in changing gene frequencies has been formalized mathematically (see Fisher, 1949; Wright, 1921). A large body of data is available on the genetical basis of the sex and incompatibility mechanisms promoting
