It is relatively old and should be updated in the coming year. It also has greater tolerance to waterlogging and manganese deficiency than narrow-leafed lupins.
Moist or wet forest on the Atlantic and Pacific slopes; alt. Description Usually solitary trunked but a rarer clustering variety is also found.
Green ringed trunk with white leaf base scars have visual affinities to bamboo Anthesis in corn, especially when planted en masse. The long, wide, tapering "S" shaped aka falcate leaflets fall from the rachis or droop a bit in a relaxed manner that just screams tropical rain forest palm.
The leaflets of this species are thinner than most,with prominent striations. Though many 'bamboo-like' Chamaedoreas have a pale line along the ventral surface of the petiole, it is the most pronounced in this species, and is a characteristic that can help identify it. Staminate with rachillae, these cm long, spreading or pendulous, yellow-green.
Staminate in very dense spirals, contiguous, Pistillate in dense or lax spirals, However, I have been unable to locate any Liebmann collections of C. Strangely, Liebmann material identified as the holotype at Copenhagen is from Oaxaca as are the isotypes at Paris and the Smithsonian Institution.
Several collectors, including Liebmann, Linden, Warscewicz, and Wendland, sent propagative material of C. One of the largest members of the genus, only C. Chamaedorea tepejilote is a variable species throughout its very wide range.
It occurs in moist or wet forests on a variety of substrates from southern Mexico to northern Colombia. Separate taxa have been proposed based principally on size, number of parts, and nervature of pinnae.
According to Standley and Steyermarkit is difficult to find constant distinguishing features and, essentially, differences are of size, not of character.
In an earlier paper Hodel d I treated C. In that paper, I maintained C.
Klotzsch described and named c. These were grown from seeds that Warscewicz had collected in Guatemala and sent to Europe in I had not seen type material of C.
However, I have since seen good type material of C. In most cases, the calyx is low, ring-like and more or less inconspicuous, like that of C.
Occasionally, there will be a shriveled, membranous, tooth-like sepal in the ring-like calyx, an uncommon but not unknown condition in C. When considering the highly variable nature of C. Chamaedorea tepejilote is widely cultivated for food in southern Mexico, Guatemala, Honduras, and El Salvador.
The unopened staminate inflorescences, resembling ears of corn, are sold in markets and used as a vegetable or in salads. They are called Pacaya, a term also used for the entire plant.
In Guatemala it is more intensely cultivated and exploited for market than in any other part of Central America. See the chapter on economic uses for a more extensive account of Pacaya.The corn pollen germinated well (about 73%) when removed from anthers 1 day before anthesis and placed on culture medium.
The lily pollen germinated poorly . Anthesis — silk interval: An indicator of stress One of the best indicators of how plants respond to stress during flowering is the Anthesis — Silk Interval, ASI. This measures the time in days between pollen shed and silk emergence.
Temperature is a primary factor affecting the rate of plant development. Warmer temperatures expected with climate change and the potential for more extreme temperature events will impact plant productivity.
Anthesis — silk interval: An indicator of stress One of the best indicators of how plants respond to stress during flowering is the Anthesis — Silk Interval, ASI. This measures the time in days between pollen shed and silk emergence.
Heterosis of sweet sorghum 29 hybrids were combined with ATx as a female parent and 29 sweet sorghum varieties as male parents for the research on heterosis in some traits such as period of duration, plant height, kernel weight and grain weight per head.
Considerable advances in our understanding of coffee seed physiology have been made in recent years. However, despite intense research efforts, there are many aspects that remain unclear. This paper gives an overview of the current understanding of the more important features concerning coffee seed.
