Basil seeds are relatively inexpensive to produce, and they can be grown in a variety of climates. The main challenge in basil seed production is the need for a consistent supply of water. Basil seeds are sensitive to drought, and they will not germinate if the soil is too dry. The average yield of basil seeds is about 1,000 pounds per acre.
The seed bank is one of the key factors for the persistence and density fluctuations of plant populations, especially for annual plants. [4] Perennial plants have vegetative propagules to facilitate forming new plants, migration into new ground, or reestablishment after being top-killed, which are analogous to seed bank in their persistence ability under disturbance.
Seeds were planted in the greenhouse in naturally highly infested soil and symptomless plants that survived in naturally infested soil were the source for F1 seeds of resistant germ plasm. Further selection tests to improve resistance were conducted up to additional generations in infested soil in the greenhouse.
Basil cultivars vary in several ways. Visually, the size and shape of the leaves varies greatly, from the large lettuce-like leaves of the Mammoth basil and Lettuce leaf basil to the tiny leaves of the Dwarf bush basil. More practically, the fragrance of the basil varies due to the varying types and quantities of essential oils contained in the ...
The efficiency of nutrient uptake by crops from fertilizers or residue release is generally thought to be similar. For example, about 50 percent recovery of N in the above-ground plant in the first year. There is some residual benefit of fertilizers as the crops take up a small amount of the nutrients two and three years later.
Fresh cut basil leaves can be stored in a couple of different ways. The first is by keeping the basil in a bouquet (just like flowers!) and the second is using an air-tight container or zip-top bag.
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. [1]
