Slide 4: 

© A.K. Chhabra The Plant Green-House grown tomato plant. It is an annual herb that may attain a height of 70 cm to over 200 cm.

Slide 5: 

The Bud View 1 Plants are covered with dense hairs. Petioles, peduncles, stem and even flowers are throughout covered with hairs Flower bud Dense hairs

Slide 6: 

The Bud View 2 Plants are covered with dense hairs. Petioles, peduncles, stem and even flowers are throughout covered with hairs Flower bud about to open

Slide 7: 

Two types of plants are present, determinate and indeterminate. In determinate types, flowers occur on each node until terminal ones are formed and the plant growth ceases. In indeterminate types, flower clusters are borne at every third internode and the main axis continues to grow indefinitely.

Slide 8: 

© A.K. Chhabra The Flower Plants have thick stems that grow erect or semi-spreading. Flowers are borne in small forked raceme cyme. They vary in numbers from 5 to 12. Flower bud Fully opened flower Flower bud about to open

Slide 9: 

Each flower is borne on short pedicel which is constricted at the middle point and it marks the position of abscission layers. Petals Calyx Pedicel

Slide 14: 

Androeciuim View 2 Stamens are 6 in number and inserted on the throat of corolla tube, filaments are bright yellow. The style is first short and later elongates. Staminal Tube surrounding gynoecium

Slide 15: 

There are 6 carpels that are united and the basal ovary is typically 6-celled with a central fleshy placenta. Carpel 1 Carpel 2 Carpel 3 6 carples Style

Calyx Sepals

Slide 31: 

Dehiscence of anthers is longitudinal, 1-2 days after opening of corolla. If the pollen is shed as the style grows up through anther tube, self fertilization occurs and when the stigma protrudes, chances of cross pollination through bees increase. The optimum temperature for pollination is around 21oC. Calyx Dehisced Anthers
