Carnation is a half hardy perennial with branching stems and tumid joints.
Leaf blades are simple, entire and usually narrow. Each stems form a terminal flower and hence inflorescence is generally polyhoise terminal cyme. Perpetual flowering and green house carnations are of modern origin. For Two years Chromosome no.

Growing region wise Varieties of carnation. Success and failure of carnation crop depends upon the selection of cuttings for planting. The selection and production of high quality carnation cuttings requires high degree of specialization. The stem tip cuttings must be of good diameter and have closely spaced leaves. The cuttings must be taken at the stage of vegetative growth. The stock plant must be pinched and cuttings should be harvested regularly, when the shoots are long enough to make cuttings.
Top of the plant is removed leaving 5 to 6 paired leaves on the plant. For spray type, length of cutting should be 7 to 10 cm, while in case of standard type, 10 to 15cm long cuttings are preferred, cuttings roots in 2 — 3 weeks, if they are placed in favorable environment.
Treating the cut ends with ppm IBA, encourages more roots. Misting water in the propagation units helps in better rooting. Soil for carnation crop: Red sandy loam soil with good drainage is best for the cultivation of carnation, land polyhead up to 80 — cm deep.
Optimum soil pH is 6. Addition of sulphur or acid forming fertilizers will reduce the soil pH if it is on the higher side. Basal fertilizers application in carnation: Throughly mix with the soil and water plant after 2 weeks. This should be followed very strictly. Before planting, place 7. Plant the rooted cuttings as shallow as possible. Do not press the soil, because it may cause fusarium rot disease, which leads to the mortality of plants.
Immediately after planting, drench with 1 g carbendazim or captan per lit of water.
Continuous spraying of water should be carnattion to maintain the soil wetness i. Three weeks after planting. B — Tank Tuesday, Polyhouss, Saturday. Mono ammonium phosphate Sulphate of potash 0: Sunday plain irrigation water. Over watering and poor drainage cause root death and stunted growth. Water logging would cause deprival of oxygen to plants. The growing medium should be evenly moist.
To ensure straight stems, the carnation crop needs to be supported with 4 or 5 layers of support material. Good support material is metal wire with a mesh width of 7. The poles carnatkon the beginning and the end of each bed should be strong enough and be in cast concrete. For an optimal support of the cultivatjon, an increasingly width of meshes may be used. Bottom net of 7.
Pinching is an important operation in the successful production of quality carnation. There are generally two types of pinching used. This method facilitates more rapid flowering but all stems flower at same time.
After the establishment of plants, about 3 — 4 weeks after planting, the apex shoot is pinched leaving on the 5th — 6th pair of leaf or leaving 5 — 6 lateral shoots to develop. After initial pinch, one half of the breaks from the first pinch are pinched a second time about three to five weeks after first pinch.
This method result in cultkvation yields in first flush compared to single pinch method, it will result in more even and stable production over time follows pinching with spray of fungicides.

The practice of removing undesirable immature flower buds other than central terminal bud is called disbudding. But in case of spray carnations only the central terminal bud is removed to encourage lateral flower buds to develop care must be taken to avoid any injury to the main stem. It is found to influence flowering in carnation.
Polyhouwe Asatap Acephate 0. Apply Thionet Phorate 6. Diseases of Carnation crop: Black spot Alternaria dianthi: The disease is characterized by appearance of round purplish spots on the leaves, enlarging slowly with brownish black centre having sporulation.
The leaf tissues surrounding this spot turn yellow, severe infection leads to premature death carnatipn the leaves. The fungus is usually identified by the development of fuzzy, grayish spore over the surface of the rotted tissues.
The fungus causes a brown rotting and blighting of affected tissues. Blooms are worst affected resulting in poor quality.
Withering and polyhuose of foliage, leaf death external browning of stems and internal browning at nods appear. Stem and root rot may take place. Lower leaves become purple and dry shortening and blackening of stems take place and rotting of cultvation can be observed.
Fusarium Stem rot and wilt: Physiological Disorders in Carnation crop: It is a major problem in carnation. This is due to fluctuation in temp. Polyhoouse petals cup upwards and do not open. This is due to ethylene gas emitted by fruits and vegetables. This is controlled by not mixing the flowers with vegetables and fruits during storage and transit. Keep ethylene absorbant tablet like purfil pad. Malformed flower buds, short stems and excessive branching.
Harvesting of Carnation crop: Spray types are harvested when two flowers are open and the bud shows colour. Grading of Carnation Cut flower: Commercially used Floral Preservatives.
