Reduced Pollination Efficiency Compromises Some Physicochemical Qualities in Gac (Momordica cochinchinensis Spreng.) Fruit

open access: yesAgronomy, 2021
Gac is valued for the nutritious aril surrounding its seed. When pollinators are limited or when flower sex expression is female-biased, hand pollination is necessary. Here, female flowers were hand pollinated with male flowers or pollen stored for up to

Low temperature storage of almond pollen [PDF]

open access: yesHortScience, 2002
2 pages. Pollen of the California almond cultivars Nonpareil, Ne Plus Ultra, Sonora, and Peerless was evaluated for viability following storage over 12 months at 4, 0, -20, and -80 °C. The proportion of viable pollen exceeded 80% for all cultivars and for all temperatures evaluated after 2 months of storage.

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Reducing Pollen Moisture Simplifies Long-term Storage of Pecan Pollen [PDF]

open access: yesJournal of the American Society for Horticultural Science, 1991
Pecan [Carya illinoensis (Wangenh.) C. Koch] pollen was stored under reduced moisture conditions to determine if pollen viability could be maintained for long periods at either 23, 5, or - 12C. Pecan pollen was oven-dried at 35C to a constant weight and stored in moisture-proof bags.

Short-term Storage of Almond Pollen [PDF]

open access: yesHortScience, 2000
Almond [Prunus dulcis (Mill.) D.A. Webb] breeding programs require successful techniques for pollen storage. We studied the pollen viability of two almond cultivars, `Ramillete' and `Desmayo Largueta', during 8 weeks of storage, in conditions that simulated standard situations including storage at 4, 22, and 4 °C alternating with 22 °C (4 °C/22 °C ...
