Step by step
Solved in 3 steps
- Discuss the effect of environmental conditions on the Maturation and Ripening Stage of sugar caneKindly provide 2 examples plants having "adaptations for twining" including (i) mechanical support (ii) transportation for root materials (iii) production of new plants Kindly sketch the diagramClassification of the different morphological characteristics according to crop productivity, adaptability and marketability of certain crops.

- Ginger undergoes three (3) stages of Growth. Name and describe the these stages from Germinating stage to time for harvestingThe data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?Application of synthetic compounds could artificially modify the plant growth and development, i.e. inducing germination in dormant seeds, producing parthenocarpic fruits, promoting shoot initiation in tissue culture. Collectively, they are called ________________ which are synthetic compounds that imitate the organic naturally occurring substances that modify plant growth anddevelopment at low concentrations.

Use these symptoms to explain about the type of nutrient deficiency to your worker. (i) Burning of leaf tip and edge. (ii) Reddish purple leaf edge on lower leaves. (iii) Interveinal chlorosis. (iv) Wrinkled and unopened leaf. (v) Some of the nutrient deficiency symptoms were ohserved on new growth but some were observed at the lower leaves. How would you explain this phenomenon to your worker? (vi) What are the field guides to distinguish between biotic and abiotic causes of leaf abnormalities?
