jojoba (from the Mexican name: ho-ho-bah) – Jojoba f: the plant is a woody perennial and dioecious bush native to the Sonora Desert of Arizona, northern Mexico, and arid California; jojoba plants are either male or female; since only the female plants will produce beans and the males are only used for pollination, >>> overplanting is necessary so there are enough females; it takes plants at least three years to flower; until that time, one cannot figure out the sex; after flowering the extra males can be removed from plantages and at least another two years are required before the females will produce beans; the female flower becomes a hardened capsule, which contains one or more developing seeds; as the seeds grow within the capsule during the spring and summer months, the capsule wall becomes thinner until dried; the capsule ultimately splits and the matured seed drops to the ground; the color and shape of jojoba seeds are reminiscent of coffee bean; jojoba is the only plant that produces significant quantities of liquid wax esters akin to the natural restorative esters produced by human sebaceous glands; currently all jojoba beans are from wild plants; it is grown commercially in Argentina, Israel, and Australia, in addition to the US and Mexico; the plants produces beans which contain up to 50–54% their weight in oil; the oil found in the bean is similar to that found in the sperm whale; recently it was demonstrated in Arabia, where it is also grown in salty deserts, that the oil is extremely useful for diesel engines as well; Simmondsia chinensis (Simmondsiaceae), 2n = 4x = 52 (the sex cannot be identified until flowering stage [2–5 years age]; sex chromosomes are not distinguishable; therefore, sex type of jojoba seedlings cannot be determined by cytological methods; the plantation with seeds usually results in 84% male and 16% female plants whereas only 10% male plants are desirable for optimal yield; two male-specific markers of ~25 bp and ~325 bp were identified using primer combinations EcoRI-GC/MseI-GCG and EcoRI-TAC/MseI-GCG, respectively; a female-specific marker of ~270 bp was identified with the primer combination EcoRI-TAC/MseI-GCG) hort >>> agroenergy crop >>> Picture 006

maize, corn US - Mais m: it is the world's forth most important crop, behind only wheat, rice, and potatoes; there are more than 327 million acres of maize planted each year, worldwide; US produces over 526 millions US tons per year; other countries that produce a large amount of maize include: Africa, Argentina, Brazil, China, France, India, Mexico, Romania, Russia, and South Africa; the best place to grow maize is in well-aerated, deep, warm soil with a lot of organic matter, nitrogen (N), phosphorus (P), and potassium (K); semi-high summer temperatures, warm nights, and adequate, well distributed rainfall helps it even more during the growing season; the growing season and day length also have a factor on growth; maize evolved in Mexico or Central America about 6,000 years ago; it developed from a small wild plant with a pod-pop of cob; modern maize has its cob enclosed in the one sheath, which prevents dissemination of seed; it has imperfect flowers; it is monoecious, cross-pollinating; almost all maize grown maize in the world are hybrid maizes; there are seven types of maize: (a) flint; flint maize kernels are hard and smooth and have little soft starch; flint was probably the first maize Europeans ever laid eyes on; is not grown in USA as much as it is in Asia, Central America, Europe, and South America; in temperate zones, flint maize matures earlier, has better germination, and the plant vigor is earlier than in dent, (b) flour; flour maize contains a lot of soft starch, and has almost no dent; though it is not used much anymore, it is grown in the drier sections of the USA and in the Andean region of South America; it is an older type of maize, and was found in a lot of graves of the Aztecs and Incas; since the kernel is so soft, the American Indians could make it into flour, (c) pop; it is an extreme form of flint; it has a very small proportion of soft starch; it is a very minor crop, and is gown mostly for humans to eat;  the reason is "pops" so well, is because of the horny endosperm, which is a tough, stretchy material that can resist the pressure of steam, which is generated in the hot kernel until it has enough force to explode or "pop", (d) sweet; this type of maize has an almost clear, horny kernel when it is still young; the kernels become wrinkled when dry; the ears can be eaten fresh, or can be stored in cans; the only difference between sweet and dent maize is that sweet genotype has a gene, which prevents some sugar from being converted into starch; it is grown a lot as a winter crop, in the southern USA, (e) dent; getting its name from the dent in the crown of the seed is grown more than any other type of maize; millions of tons of grain are produced from dent corn; it is used for human and industrial use, and for livestock feed; the starch reaches the summit of the seed, and the sides are also starchy; the denting is caused by the drying and shrinking of the starch; the dent corn grown in the Corn Belt of USA came from a mix of New England flints and gourseed (an old variety of corn grown by the Indians in southeaster North America, (f) waxy; seeds appear waxy; chemically, it has a different type of starch than normal starch; it was developed in China, and some waxy mutations have occurred in America dent strains; very little is grown, and that which is, is used for producing a starch similar to tapioca starch, (g) pod; pod maize is not grown commercially, but it is used a lot in studying the phylogenesis of maize; it resembles varieties of the primitive forms; every seed is enclosed in a pod and the whole ear is also enclosed in a husk; recent molecular studies demonstrated that the two main modern divisions of maize arose about 3,000 years ago, as maize arrived in what is now the southwestern USA and, at about the same time, on the islands of the Caribbean;  temperate maize spread further north and east across North America, while tropical maize spread south; the temperate-tropical division remains today; what maintains it are differences in disease susceptibility and photosensitivity — essentially, how daylength affects flowering time;  the two maize types are now so different from each other that they do not cross well, and their hybrids are not well adapted anywhere, Zea mays (Gramineae), 2n = 2x = 20; 2C DNA content 4.9-12.6 pg = 2400-3200 Mb agr >>> Tables 15, 16, 32, 35, 48 >>> Picture 010
