Presentation Transcript

Slide 1

Water Relation to Plants

Slide 2

Properties of Water Associated Uses of Water Dissolves soil minerals, sugar, amino acids, most stretched out scope of any fluid! Polar Solvent Does not pack, so turgor weight underpins plant tissue, licenses stream of material in xylem (transpiration) and phloem (translocation) Hydraulic Fluid Reactant: CO 2 + H 2 O - > O 2 + CH 2 O Product: CH 2 O + O 2 - > H 2 O + CO 2 PSN Reactive Resp High Specific Heat Buffer: 1 Calorie = 1 Liter 1°C Water fluid >gas expels vitality from surface Evaporative cooling High Heat of Fusion

Slide 3

Sources of Water Precipitation: Fog, Mist, Rain, Snow, Sleet, Hail Runoff: Brook, Creek, Stream, River Water Table: Puddle, Pond, Lake (Ocean not freshwater) Soil Water: Most valuable for plants Aquifers: permeable shake, wells, artesian wells, springs

Slide 4

friable Mud Field Capacity Wilting Point Dry Soil trickles! warm! Gravitational Water Capillary Water Hygroscopic Water Runoff Unavailable Held between soil particles Erosion Available to plant roots!

Slide 5

Irrigation Methods Sprinkler: Wastes over half of water utilized Water drops on leaves: dead spots Humidity prompts to contagious infections Kills "eggs" (zygotes!) of many "bugs" May apply manure/insectide at same time Surface: Less inefficient, no water spots, yes compost Not pesticide unless "systemic" Furrow water system (trenches between columns of field) Flood water system (un-level field, one wrinkle at top of the line) Trickle: Even less inefficient, strategy in our nursery Computer programming for considerably more even conditions Wick: Capillary tangle with ebb-stream pumping of manure and water… plants take just what is required. Characteristic: 4 crawls of rain required every month. Watch the news, read USA today, surf Wunderground.com. Flood just when required… IF required… MOST CONSERVATIVE!

Slide 6

How Much? How Often? Many individuals kill their plants with graciousness (8 glasses for every day) Keeping soil friable: Between Field Capacity and Wilting Point Water to handle limit Allow to sit in sun for a long time (week) until withering You needn't bother with a Green Thumb! Grimy Finger Method: Put Finger in Soil If finger is wet, cool, messy: NOT YET! In the event that finger is dry, warm, clean: OK to Irrigate

Slide 7

When would it be advisable for me to flood? Late morning? Keep in mind the water spots, amplifying focal points? Evening? Soil warm from evening, include water = organisms Morning? Soil cool for less vanishing waste Spots dissipate from leaves before sun gets high √ Other Pointers: Preserve water in soil with mulch Proper separating of plants maintains a strategic distance from soil warming and dissipation Water less frequently yet more profoundly to empower further establishing Lighten waterlogging dirt soils with sand or perlite!

Slide 8

Plant Factors Affecting Water Needs More Less √ It is a seedling √ It is developing quickly √ It is repeating (blooms and natural products) √ It is lethargic It has succulent leaves √ It has waxy leaves √ It has furry leaves √ It has thin, fine, dismembered leaves √ It has profound roots √

Slide 9

Environmental Factors Affecting Water Needs More Less √ It is in a mud soil √ It is in a sandy soil √ The temperature is hot √ The wind is blowing The dampness is high √ The sun is brilliant (no mists) √

Slide 10

Symptoms of Overwatering Symptoms of Underwatering Organs swell, air out Fungi flourish (Damp-off) Yellowing of leaves Root Death by Asphyxiation Wilting Growth Inhibition (Dwarfing) Leaves with chestnut tips and edges Blueing of leaves Abscission of leaves Wilting Notice that the common manifestation is WILTING! This prompts to much overwatering! These side effects are effectively clarified by understanding OSMOSIS!

Slide 11

0 M hypotonic Osmosis: the aloof development of water from a place that is purer water to a place that is more dirtied weight increment estimate increment turgor weight increment deluge stops when it can't defeat divider weight 0.3 M 0.25 M 0 M hypotonic Water moves into the cell

Slide 12

3 M Osmosis: the inactive development of water from a place that is purer water to a place that is more contaminated weight diminish measure diminish turgor weight to 0 efflux stops when the focuses coordinate plasmolysis: layer pulls far from cell divider 0.3 M 3 M cytosol arrangement 3 M hypertonic Water moves out of the cell

Slide 13

Osmosis: the latent development of water from a place that is purer water to a place that is more contaminated no weight change no size change no turgor weight change 0.3 M 0.3 M isotonic Water moves into and out of the cell at same rate!
