An important factor affecting the condition to cut flowers during the transportation is Geotropism.
Geotropism is a growth response to gravity.
Certain responses of cut flowers to environmental stimuli (tropisms) can result in quality loss. Most important is geotropism (bending away from gravity) and phototropism (bending toward the light). Geotropism often reduces quality in spike-flower crops like gladiolus, snapdragon, stock, roses and gerbera, because the flower stems (pedicels) or the main stem bends upward when stored horizontally.
Geotropism is greatly reduced when flowers are maintained at low temperatures where this is not possible, such flowers should be handled upright.

Botanically, the fruit of litchi is a Nut.
Botanically litchi belongs to Sapindaceae family. The fruit is a one-seeded nut, develops in bunches, and varies in shape and size. The edible portion of litchi called aril lies under the papillate, pinkish-red pericarp and surrounds the dark-brown, oily-skinned seed. The Litchi plant requires a warm, humid climate for vegetative growth.

Z scheme of electron transport was 1^st proposed by Hill and Bendall. It includes both the PS I and PS II photosystems.
The Z scheme is an energy diagram for electron transfer in the "light reactions" of plant photosynthesis. A mechanism to convert light energy into electrical energy, which is then converted into chemical energy in the form of reduced NADPH and ATP.
It applies equally well to photosynthesis by algae and cyanobacteria. The vertical energy scale shows each molecule's ability to transfer an electron to (i.e., to reduce) the next one from left to right.

In India, the red soil is mostly found in Tamil Nadu state.
Red soil is a type of soil that typically develops in warm, temperate and humid climates and comprises approximately 13% of Earth's soils. It contains thin organic and organic-mineral layers of highly leached soil resting on a red layer of alluvium.
It is usually low in nutrients and humus and can be difficult to cultivate due to its low water holding capacity, however, the fertility of these soils can be optimized with liming and other farming techniques.

International Potato Center was established in 1967 in Peru.
The International Potato Centre is a research facility based in Lima, Peru that seeks to reduce poverty and achieve food security on a sustained basis in developing countries through scientific research and related activities on potato, sweet potato, other root and tuber crops and on the improved management of natural resources in the Andes and other mountain areas.

Karol is the common name for Spine gourd.
It is a species of flowering plant in the Cucurbitaceae/gourd family.
It is propagated by underground tubers. It has small leaves and small yellow flowers and it has small, dark green, round or oval fruits. It is dioecious, which means that it has distinct male and female individual organisms.
Momordica dioica as the average nutritional value per 100 g of edible fruit was found to contain 84.1 g moisture, 7.7 g carbohydrate, 3.1 g protein, 3.1 g fat, 3.0 g fibre, and 1.1 g minerals. It also contained small quantities of carotene and vitamins like ascorbic acid, thiamine, riboflavin and niacin.

French basil belongs to the family Lamiaceae.
Also called great basil, is a culinary herb of the family Lamiaceae (mints). It is a tender plant and is used in cuisines worldwide.
Basil is an annual, or sometimes perennial, herb used for its leaves. Basil grows a thick, central taproot. Its flowers are small and white and grow from a central inflorescence or spike, that emerges from the central stem atop the plant.

The Genetic Engineering Approval Committee (GEAC) is an apex body under which the following Ministry of Environment and Forests.
As per Rules, 1989, it is responsible for the appraisal of activities involving large-scale use of hazardous microorganisms and recombinants in research and industrial production from the environmental angle.
The committee is also responsible for the appraisal of proposals relating to the release of genetically engineered (GE) organisms and products into the environment including experimental field trials.

Sheetal variety related to Cucumber vegetables.
It is an F1 hybrid, high-yielding variety of cucumber. It can be harvested 40 - 45 days after harvesting. The length of the fruit is 22 - 23 cm, cylindrical in shape and light green in colour.

The indicator plant for fluoride pollution is Gladiolus.
The most widely used fluoride bioindicator is Gladiolus. This plant is showing typical fluoride injury. Varieties differ enormously in sensitivity and cultivation also seems to affect response.
The use of Gladiolus plants was an effective biomonitoring technique for assessing the impact of atmospheric fluoride concentrations near a small-scale, poorly managed brick kiln in South Asia.
