Relative humidity (RH) is the amount of water vapor in the air, expressed as the proportion (in percent) of the maximum amount of water vapor it can hold at certain temperature. MADER SS. Water balance information would be ideal (precipitation received, amounts lost from run-off and deep percolation and from evapotranspiration), but lesser detail can be useful iii) Slope and direction : Slope and directions influence the local climate. This causes growth to cease and the tree to become dormant for 3 to 5 months. McGraw-Hill, Inc. p. 87-130. All the impacts related to the climate change may affect distribution and biodiversity of whole plant communities. These factors are: Light; Temperature; Water; Mineral nutrients; Light. Temperature extremes in climate . It is important to understand how these factors affect plant growth and development. Oxygen is essential in respiration for the production of energy that is utilized in various growth and development processes. Radiant Energy: Radiant energy is a significant factor in plant growth and development. I. Precipitation are clouds that become heavy with condensation , the droplets can no longer stay afloat in the air so it comes down in the form of rain , snow , hail sleet, all forms of precipitation . It is the falling of water in droplets on the surface of the Earth from clouds. In the western United States, warming and drought stress are causing trees to die and making them more vulnerable to pine beetle and other insect infestations. As a consequence many areas are unsuitable for crop cultivation.2. Data mining plays a chief role in the fields of e-commerce, healthcare sector, and agricultural sector. Pressure 5. 2005. Weather-sensitive load also includes appliance of agricultural irrigation due to the need of the cultivated plants. Where both cold and warm air occur in proximity, as over a lake and its adjacent shore, the cold flows to the direction of the warm air or from high to low pressure area to correct the pressure imbalance. Video Lecture on Factors Affecting Plant Growth from Plant Growth and Development chapter of Class 11 Biology for HSC, CBSE & NEET. Irrigation: Global warming affects more than just plant biodiversity—it even alters the way plants grow. Plant growth and development are influenced by physical, chemical and biological components in the plants environment. It affects or determines plant growth and development. The reasons are outlined below:PhysicalClimateClimatic factors include...1. The climatic factors are abiotic or non-living components of the environmental factors (outside of genetic factors) that affect plant growth and development. Mugabe. in vegetable production, these factors should always be considered to ensure good result. (Devlin 1975; Edmond et al. Data mining is used in agriculture to predict crop productivity, water management, crop disease management, pesticide recommendation by using different algorithms. Previous studies showed that biological environment would have effect on plant morphology, especially blade size, texture, thickness and plant morphology (Huang et al., 2009). Any factor in the plants’ environment that is less than optimum, whether it is deficient or in excess, will limit plant growth (17). There is already evidence that plant species are shifting their ranges in altitude and latitude as a response to changing regional climates. , 2007 ), along with the other responses. Another factor influencing reduced plant growth and yields include the allocation of resources; following drought stress plants will allocate more resources to roots to aid in water uptake increasing root growth and reducing the growth of other plant parts while decreasing yields. Genetic factors . The remainder consists of argon (slightly less than 1%), carbon dioxide (0.036%), and traces of other gases. Grassed filter strips used in farm fields help in minimizing runoff and erosion by decelerating water velocities in the vegetated areas.
