Shivat HaMinim The Seven Species of Israel
Seedling Stage • Seedling Stage •The first stage of growth in wheat is called the seedling stage. This stage occurs after germination and begins when the first true leaves emerge from the soil, and ends when the first tiller emerges. During the seedling stage the second leaves are just emerging and beginning to unroll, and there are as many as six seminal roots.
Tillering Stage • Tillering Stage •Tillers are new shoots that are sent up from the root of the plant. Each tiller can grow its own stalk and seed head, so the number of tillers will determine the potential yield of the plant. Tillering can occur either before or after the winter dormancy stage in winter wheat, and a plant can have as many as six tillers. Tillers can be distinguished from true leaves by a sheath at the base of the growth called a prophyll.
Jointing Stage •The jointing stage starts when the stalk forms its second node, a hard joint from which the plant telescopes upwards. During the jointing stage, the smaller, less-formed tillers often die off. It is important that all the wheat in a field reaches the jointing stage at the same time so that the heads will all be mature at harvest time.
Heading and Flowering Stage • Heading and Flowering Stage •The heading and flowering stage begins when the awns emerge from the sheath. When the awns have emerged the flowering begins and pollination and fertilization occurs. It is important again during the flowering stage that all the plants in a field flower at the same time. Right after fertilization, the embryo and endosperm begin to form.
Booting Stage •During the booting stage, the head of the wheat develops and becomes visible beneath the sheath on the stalk. The booting stage ends when the tips of the head, called awns, begin to emerge
Maturity Stage Maturity Stage • The maturity stage immediately follows fertilization, and includes several short stages. The milk stage is the first part of maturing, and this is when the kernel begins forming. The kernel is fully formed during the dough stage, and the plant takes nutrients from the stalk and leaves and transfers them to the kernel. The kernel is still very moist at the end of the dough stage and contains about 30 percent water. During the ripening stage the kernel loses the rest of its moisture and is ready to be harvested.
Geographic Range • Geographic Range •Barley grows in more regions than any other cereal plant. The most common places to grow barley in the United States are North Dakota, Washington, Montana and Idaho
Climate • Climate •Barley prefers mild winter climates that are cool and dry. It adapts easily to higher altitudes with short, cold winters
Soil Condition • Soil Condition •This grain does well in semi-arid conditions. It can tolerate alkaline soils but does not thrive nearly as well in acidic soils.
Maturation • Barley matures at a quicker rate than most other cereal plants. The amount of days to maturation depends on the variety you choose. The grain is mature when the kernel moisture dips to about 40 percent. Barley will grow to 30 inches in height depending on the variety.
Bud break • Bud break is the first stage after the plants start coming out of their dormancy. Prune grapes during dormancy; this is critical for bud development. The newly appearing buds are susceptible to damage from frost and hence need to be protected. Dependent on specific weather conditions, the new leaves commonly appear three to four weeks after bud break. This is also the time when the vines maximize their food storage through photosynthesis. Grapevines are also prone to powdery mildew disease during this stage, which can be controlled with the use of antifungal sprays. The plants can also show extra shoot growth and these have to be removed so as to maximize the energy for the optimal development of flowers.
Flowering • The vines start to develop flower clusters within about 10 weeks of the initial bud break. This is usually in May or early June. The period of flowering is determined by the grape variety and the weather conditions in the area. This is also the time for the pollination of the flowers, which is necessary for the formation of the fruit. Very hot temperatures and heavy rain can impede good pollination. It only takes a week or two for the flowers to get pollinated and if the weather is not right during this period it results in a smaller sized fruit.
Fruit Set • ◦In the fruit set stage, the pollinated or fertilized flowers start to turn into grapes and the flowers that were not pollinated drop off the tree. Young fruit needs to be protected from night chills or any frosts in the area. The grapevines need heavy watering at this stage to prevent the berries from drying out. The fruit cells undergo division in this stage and continue to get larger. Thin shoots and leaves on the vines frequently to create ample space to accommodate the growing grapes. Protect the fruits from bright and direct sun at this stage as this can cause sun scald.
Veraison • Veraison refers to the coloring of the grapes and the stage is characterized by the color development in the fruit and their softening. The softening of the fruit is the result of the accumulated sugars in the grapes and can also be considered the ripening stage. The color of the grapes is directly determined by the variety. In order to produce a good color many growers lift the canopy or shade from the vines at this stage. Veraison continues till late July and then tapers off.
Harvest • The last stage comprises of harvesting the mature grapes. Again the final maturity time of the grapes is dependent upon variety. Generally the period of maturity is reached about 100 days after the development of flowers. The grapes are first tested for sugar and acid levels before they are harvested. The life cycle of the grapevines ends in the fall and the plants start to recede into dormancy and their leaves start to fall off. Pruning is critical during dormancy as this protects the plants from periods of extreme frost.
Germination • •Fig seeds are extremely hard to germinate and have very low viability. Germination typically takes a week. During the germination stage, the seed sprouts, roots develop and the stem begins to form.
Primary Growth Stage Primary Growth Stage •As a young sapling, the fig tree's root system establishes and expands, the stem of the tree grows and strengthens into what will one day be a trunk. Primary branches develop out of the main root stem, and leaves begin to form on the low branches. After the first year, the plant can begin to hold up to pruning. •In this stage, it is only necessary to prune the plant to lightly shape it and train future growth. Ideally, you should not prune the plant until it's mature. R
Secondary Growth Stage • Secondary Growth Stage •After a year, the fig tree enters the secondary growth stage. The first branches and bark grow more firm, secondary branches develop and leaf development continues. Roots spread wider and harden, and bark forms to strengthen the trunk.

Maturity • Maturity •Bearing fruit is the point of maturity for a fig tree. The branches and bark strengthen further to prepare for he weight of the fruit. Fig trees bear fruit in two harvests: the first in the spring from the old growth, called the breba crop, and the second in the fall, known as the main crop, with fruit harvested from the new foliage growthAfter each harvest, you can prune the tree to maximize subsequent harvests and to maintain the desired shape of the plant.

Reproduction • 1.Reproduction ◦The fig tree doesn't have a separate flowering stage since the flower actually develops in clusters inside the fruit itself, where the pollinating insect will climb inside the fruit, technically the syconium, and find the flowers (most species of fig pollinate this way).Many domestically cultivated figs have been hybridized to be self-pollinating. In a self-pollinating fig tree, everything that is needed for the plant's reproduction is inside its own fruit.

Types of Palm Trees • Types of Palm Trees •The familiar tropical coconut palm is native to Malaysia but has spread throughout the world's tropical regions. Smaller species such as the areca palm often serve well as houseplants. Several species in the Phoenix genus produce dates, which are cultivated in Africa and other tropical regions.

Age at Maturity • Age at Maturity •Many species of palms are relatively slow-growing trees. Depending on their growing conditions, some palms must be 10 years old or older before they begin to produce flowers, which if pollinated, grow into fruit such as dates or coconuts. Each date contains one seed; each coconut is a seed unto itself. When these seeds are properly germinated, they produce another palm tree.
