ABSTRACT Different products have been tested to increase the vase life of cut flowers after harvest such as biodegradable films. These used in fruits since application on surface may provide modification atmosphere around it, although, there is no information for flowers. The objective was evaluate effectiveness cassava starch films a postharvest product Red Torch Ginger inflorescences. On firs...

Objective: To determine the stigma receptivity and pollen viability in order to make manual crosses obtain viable progeny castor bean (Ricinus communis L.).Design/Methodology/Approach: Pollen tests were made on breeding materials by staining with acetocarmine solution. In elite materials, of was evaluated hydrogen peroxide. From inflorescences, male ones removed female preserved, which covered ...

The odoriferous compounds produced at the time of flowering by the inflorescences of 5 arum lily species were condensed in dry ice traps. The components of the condensates were separated by paper chromatography and identified on the basis of position and color reactions in comparison with known compounds. The concentration of free amino acids in the appendix of Sauromatum guttatum Schott increa...

• As we know, the inflorescences that will produce any year’s grape crop start differentiating inside the buds in the previous year. There are 2 main stages of development: formation of primary branches starts in Year 1, before the vine goes dormant; secondary and tertiary branching, as well as individual flower differentiation, continues around budbreak of Year 2. Thus, the cropping potential ...

• Flower formation in grapevines follows 3 steps: 1) formation of uncommitted primordia, also called anlagen, within the latent buds; 2) differentiation of uncommitted primordia into inflorescence primordia; and 3) differentiation of inflorescence primordia into individual flowers . Steps 1 and 2 happen during the previous season, whereas Step 3 does not happen until budbreak of the current sea...

A new species of Coespeletia from the páramos of Mérida (Venezuela) is described here. This species, named Coespeletia palustris, is found in a few marshy areas of the páramo. It is closely related to C. moritziana, but differs from it in a smaller number of florets in the capitula, larger ray flowers with longer ligulae and longer linguiform appendages, smaller pollen grains, larger cypselae, ...
