SPECIAL HORTICULTURAL PRACTISE IN CARNATION Training Pinching Single pinch Pinch and-a-half Double pinch De shooting Disbudding Calyx banding Netting


TRAINING Training is a very important and continuous operation in carnation cultivation. This operation helps in keeping the plants within the specified area . the net to grow straight without bending at the bottom.

Pinching :

Pinching Pinching is an important operation which helps to ensure maximum number as well as quality of flowers. Some cultivars do not require pinching but some cultivars require. This operation to encourage branching. Pinching should be done approximately 3-4 weeks after planting. Three types of pinching are being adopted in carnation

PowerPoint Presentation:

Three Types Of pinching Single pinch Pinch and-a-half Double pinch

Single pinch:

Single pinch In this method, the top of the main or leader shoot is removed leaving 5 pairs of leaves from which 4-5 lateral shoots develop. These lateral shoots will produce flowers at the same time. This method is particularly applicable to cultivars which produce higher proportion of quality blooms like the hybrid standard carnations.

Single Pinching Methods:

Single Pinching Methods Before pinching After pinching 35 days after pinching

Pinch and-a-half:

Pinch and-a-half This method is followed to regulate the supply of flowers throughout the year. It involves the removal of main stem tip to induce 4-5 lateral shoots. When these lateral shoots develop 5-6 pairs of leaves, only half the number of the lateral shoots are pinched. This method provides steady supply of flowers but reduces the quantity of the first crop.

Double pinch:

Double pinch In this method the main shoot is pinched once followed by pinching of all the lateral shoots arising from the first pinch when they are about 6-8 cm long or develop 5-6 pairs of leaves. This method produces larger number of flower bearing shoots but produce weak shoots and poor quality flowers . So this method is not commonly followed.

Deshooting :

Deshooting Unwanted secondary shoots on the flowering stems are removed when they are about 2-3 cm long.

Disbudding :

Disbudding Disbudding is practiced in standard and spray or miniature carnations . In standard carnations, disbudding is practiced for getting good quality flowers. The axillary /lateral buds are removed just after appearance, without damaging the leaves and stems. Usually those axillary buds about six nodes below the terminal flower buds are removed to encourage the development of the main flower bud. In spray or miniature carnations, the main flower bud (terminal bud) is removed to encourage the lateral flower buds to develop.

Calyx banding:

Calyx banding Calyx splitting is a physiological disorder in carnation affecting the flower quality. This disorder can be minimized by calyx banding. Calyx banding is the practice of placing a rubber band or plastic tape around the calyx of the flower bud when it just begins to open.

Netting Both standard and spray carnations require support. Lack of support leads to bending of stems ultimately causing decline in market quality. Poorly supported branches easily break, making them susceptible to diseases. Various kinds of plastic mesh, string, bamboo canes, etc. are used for plant support. In recent times, nets are used for supporting carnation plants .

PowerPoint Presentation:

The nets are usually laid out in 4 or 5 layers. Before planting , the first layer of netting should be laid out. The main frames can be fixed before bed making. The frames can be made from ‘L’ angles or pipes . The netting can be done with GI wire of 16 gauge for length wise fixing and nylon threads for width.

PowerPoint Presentation:

An increasing width of the meshes is used from bottom upwards . Generally , the bottom net is 7.5 x 7.5 cm, the subsequent nets are 10 x 10 cm, 12.5 x 12.5 cm and the upper net 15 x 15 cm . As the plants grow, the second, third and fourth layers can be put at 20 cm distance. Readymade nylon nets can also be used which will save labour and time .
