Flower pistillate

Blond Lebanese hash consists of a matrix including flower pistils, leaf and flower particle debris, non-resin-bearing cystolith hairs, conical trichomes and resin nodules. Above, this is shown magnified about 500 times by an electron scanning microscope. Below is water-pressed Afghani hash in which the resin nodules (magnified about 250 times) are largely undissolved. 

Inflorescences dioecious spikes, so on separate plants. Staminate spikes forming deciduous catkins of yellowish flowers, pistillate as persistent spikes of green flowers, at length maturing fruit. 

AAB inhabit the surface of flowers (pistil), fruits, and their fermented products such as vinegar, sake, wine, or beer (Asai 1968), and thus seem to be evolved in adapting to such a specific environment where high concentrations of sugars, alcohols, or sugar alcohols exist in highly aerobic conditions. In such a specific environment, there are many oxidative bacteria such as Burkholderia, Ralstonia, Xanthomonas, Frateuria, Sphingomonas, and Sinorhizobium, from a- to y-Proteobacteria, which have quinoproteins and flavoprotein-cytochrome c complexes. The former...

Dioecious In the lower plants referring to the individuals having the archegonia and antheridia on separate plants referring also to those seed plants having staminate and pistillate flowers borne on different individuals. 

Disk In composites, the central portion of the head composed of the tubular flowers in many other species of flowering plants an enlargement of the receptacle around the pistil or androecium. 

Monoecious Having the archegonia or female sex organ and antheridia or male sex organ on different branches of the same plant or producing staminate and pistillate flowers on a single plant. 

Flower sex expression of cucumbers can be modified by treating seedlings with several growthregulating substances With the exception of gibberellin, chemicals tend to reduce the number, or suppress the development, of staminate flowers, and increase the number or accelerate the development of pistillate flowers Gibberellin, in contrast, increases the number of staminate flowers in monoecious cucumbers and results in the formation of staminate flowers on gynoecious cucumbers which otherwise would produce only pistillate flowers In promotive effects on staminate flower formation and vegetative extension, GA4 is approximately tenfold more active than GA3 ... 

Flower sex expression is subject to genetic, environmental, and chemical control (6, 14, 20, 26, 27). Alteration of the length or duration of any of the flower sex stages, but not necessarily the order of appearance, has been modified by environment. The staminate stage has been extended by long photoperiods (6,26) and the appearance of the pistillate stage accelerated by low temperatures, short days (3), and low light intensities (26). Numerous chemicals (Table I)...

Pistillate flowers are usually formed earlier (at a lower node) when plants are grown under a short photoperiod. A similar but less striking effect can be induced by a brief (2- to 3-week) exposure of cucumber seedlings, beginning at cotyledon expansion, to a short photoperiod, followed by an extended photoperiod (3).

Inspection of flower primordia in the Japanese cucumber, Somohanhiak, revealed that both staminate and pistillate primordia are present in each flower, and sex expression at anthesis is apparently dependent upon the relative growth rates of the two types of primordia (10). Perhaps this is also true for other cucumber varieties. Thus, environmental or chemical alterations in flower sex expression probably fall under the category of regulation which is an effect on development or maturation, rather than induction or differentiation. 

Cannabis (Indian hemp, American hemp [listed in the U.S.P. from 1873 to 1942]) consists of the dried flowering tops of the pistillate plants of Cannabis sativa Linne. The plant is an annual... 

The amount of resin found in the pistillate flowering tops of C. sativa markedly decreases as the plants are grown in more temperate climates. Thus, Indian cannabis yields 20% or more of resin Mexican cannabis, 15% or less Kentucky hemp, 8% or less and Wisconsin hemp, 6% or less. The active principles are found in the resin in about the same, or even smaller, ratios as those indicated earlier. The hemp leaves contain a small amount of the resin.
