Sucrose Needs for Pollen Germination of Impatiens Balsamina L [PDF]

, 2020
: In vitro pollen germination is the simplest method to test pollen viability and also can be exploited for study of pollen physiology. A nutrient medium (in vitro) is supplemented with some essential compounds necessary for pollen germination and tube ...

Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Assessment of Pollen Quality and Germination Dynamics in Chestnut (Castanea spp.): Implications of Genotypic Variation and Sucrose Concentration

ISPEC Journal of Agricultural Sciences
Pollen viability and germination are critical factors influencing reproductive success and nut yield in chestnuts (Castanea spp.). However, their dynamics across different genotypes and cultivars remain insufficient.

II. Researches on the germination of the pollen grain and the nutrition of the pollen tube [PDF]

Proceedings of the Royal Society of London, 1894
Abstract Many observers, especially Van Tieghem and Mangin, have established the fact that the growth of the pollen tube is a process of true germination, strictly comparable to that of the growth of the prothallus from the spore in the groups of Vascular Cryptogams.

Floral biology and propagation of blue-flowered Conospermum spp

, 2003
Blue-flowered Conospermum are endemic to Western Australia, and show great potential as cut flowers. Propagation from cuttings or seed proved difficult, and root initiation in vitro is problematic. This thesis examines the floral biology of the species

Standardization of different media for in vitro pollen germination of almond and evaluation of the germination capacity of stored pollen

, 2015
Almond is an important nut crop which, mostly for fruit set, needs the pollination of flowers followed by fertilization. Therefore, pollen viability and its germination capability are essential.

Ants contribute to raspberry pollination in protected cropping systems

Agricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Optimization of in vitro pollen storage conditions in seeded and low-seeded citrus genotypes

Environment Conservation Journal
An in vitro pollen storage study was conducted using pollen from three seeded citrus plant genotypes, viz., ‘Mexican lime’, ‘W’. Murcott’ and ‘Mosambi’ and five seedlesscitrus genotypes, viz., ‘Lisbon lemon’, ‘Jaffa’, ‘Clementine’, ‘Hamlin’ and ‘Mukaku ...

Factors Regulating In Vitro Germination of Date Palm Pollen Grams After Storage

Journal of Agricultural and Marine Sciences, 2000
Dried pollen grains of three date palm (male) cultivars grown in Oman were stored either in a freezer (-18°C), a refrigerator (4 to 5°C), or at room temperature (23 to 25°C) for 6 or 12 months.
