Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Chili pepper is a member of the nightshade family and originally a wild plant in southwestern Ecuador.
The evolution of chili pepper under the pressures of cold and low temperatures imparted the ability to tolerate cold, soil toxicities, and freezing temperature more effectively to cultivated chili pepper plants than other vegetables. Wild Chili pepper<br>
04
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Varieties of chili pepper are classified into 5 groups:
Ethnic Hot peppers
Chili pepper
Ethnic Sweet peppers
Ornamental and Bedding peppers
Sweet Bell peppers.<br>
05
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Spice chili peppers are grown for the vegetable - long, fleshy skin used as human food or spices and condiment. Spice chili pepper<br>
06
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Sweet peppers have sweet juicy flesh and are grown for making pepper sauces. Sweet peppers can also be used for salads or for making pickles. Sweet Pepper<br>

Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Stage 1 of
Chili pepper Germination Germination At optimum temperature77 t0 86oF (25 to 300 C) and moisture, the chili pepper seed germinates in 4 to 6 days.
When chili pepper seed is sown in moist soil, the seed swells due to moisture absorption.
The seed coat breaks a small shoot (coleoptile) and a primary root (radicle) emerge.
Initially the young seedlings take nutrients from the endosperm of the seed.<br>
08
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Seedling Development The shoot (coleoptile) emerge from the ground and first leaf breaks through the tip.
The mesocotyle grows during this period and a node is formed at the base of the coleoptile just below ground level.
Secondary roots begin to grow from this node, 3 to 7 days after the plant emerges from the soil. Seedlings get the nutrients through these roots. Stage 2 of

09
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Root system The chili pepper root system consists of 3 types of roots:
Primary roots
Secondary or Adventitious roots
Tap roots<br>
10
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Primary roots
These roots develop from the radicle and die subsequently.<br>
11
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Root system Secondary or Adventitious roots
These roots develop from the first node from the mesocotyle.
These rots occupy 5 to 15 cm area in the soil around the base of the stem.
Adventitious roots are small, uniform, and form a small portion of the root system. Secondary roots of
Chili pepper<br>
12
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Shoot system Chili pepper shoot system consists of stem, leaves, nodes, and internodes during the vegetative stage.
Leaves\nodes develop @ of one in 3 to 6 days.
The plant remains in vegetative stage for 30 to 40 days during which all leaves (12 to 18) are formed. Chili pepper shoot Stem Node }Inter Node Leaves<br>
13
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Shoot system About at 6 to 10 days of flowering, the Plants become very green and healthy and initiate flowers.
Chili pepper usually flowers 35 to 45 days. Flowering stage<br>
14
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Shoot system Two days after the emergence of the flowers from the shoots, the flowers begin to open.
The flowering can be observed from the white pollen from the anthers on the berry.
The maximum flowering takes place on 3rd or 4th day. It takes 6 days for the whole inflorescence to complete flowering. Flowering in chili<br>
15
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Seed Development Pepper seeds The chili pepper seed is called pepper seed. The seed matures in 30 to 35 days after fertilization.
Chili pepper seeds are round in shape but
flat on both sides.
The seeds vary in color - red, brown, white, yellow, or cream and are with a dull or pearly luster.<br>
16
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Seed Development Physiological maturity:
Maximum total dry weight of the plant reaches at the physiological maturity.
Uptake of nutrients also mostly cease at this stage.
So, if there are problems like bird damage etc. it is advantageous to harvest the crop at this stage.
As the seed moisture at this stage will be around 25 to 35%, proper drying of the seeds is important.<br>
17
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant Seed Development Physiological maturity can be determined by the dark spot on the seed.
The seed on the left is physiologically mature; the one on the right is not.<br>
18
Module I: About Chili Pepper Lesson 2: Growth of Chili Pepper plant The cultivated pepper mature and get ready for dry in 100 to 140 days depending on the variety.
The right time to harvest chili pepper is at the physiological stage of the plants or when the berry moisture content is below 45%.<br>
