Roses are grown in gardens in all parts of the world.
-
In Temperate countries, the most important period of flowering is summer.
-
In Tropical climate winter and spring, whereas,
-
In Subtropical climate round the year
LIGHT:
-
Light is one of the important growth factors which influence both temperature and water.
-
Primarily light is necessary for assimilation (photosynthesis). Through chlorophyll in the leaves, light is transformed into sugars, a process also requiring CO2 and water.
-
-
The degree to which a plant can use the amount of light available depends on several factors, for example chlorophyll contents of the leaves, CO2 supply, temperature and humidity.
-
The other indirect effect of light is the stimulation of vascular transport through the plant.
-
Rose prefers bright sunshine for the whole day, if not at least for the normal part of the day i.e., the forenoon.
-
-
The plants should be free from shades of trees and protected from the strong winds.
-
-
This process also increases the water transport, enabling nutrients, necessary for plant growth, to be distributed through the plant.
HUMIDITY:
-
-
The climactic condition of India is well suited for rose production.
-
In the northern plains rose flowers best during winter where as in temperate hilly region of the Himalayas best flowers are produced in summer.
-
Under Bangalore, Pune and such other mild climatic region we can produce good quality roses round the year.
