In the lower Himalayan region of northern India, apples are an important cash crop that contribute significantly to farmer’s livelihoods. The fruit yield in apple cultivation is declining continuously, associated with climate change and a significant decline in the population of natural pollinators. A researcher-farmer group set up two experimental apple orchards at two distinct locations: Places A and B. In apple orchards at Place A, they allowed natural pollinators to pollinate the flowers of the apple. In apple orchards at Place B, they applied mixed farming techniques of beekeeping. Along with honey, the farmer yielded apples. The yield of apples is depicted in Fig. 11.24, in terms of fruit setting (number of fruits/the total number of corresponding fruit-bearing branches) and fruit drop (premature falling of developing fruits) in the two types of experimental places of apple orchards. (i) What are the hypotheses the researcher-farmers group has thought of for this investigation? (ii) What are the different parameters in the experiment? (iii) Compare and analyse the data of two experimental orchards Places A and B, in terms of high yields of apple fruits. (iv) Based on your analysis, what do you infer from the data?

Managed bee colonies increase apple fruit setting and drastically minimize premature fruit drop compared to relying solely on natural pollination, significantly boosting overall apple orchard productivity and farm income.

Why does asexual reproduction produce offsprings that are genetically identical to the parent?

Asexual reproduction involves only a single parent and relies entirely on mitotic cell division, copying the genetic code exactly without gamete fusion, crossing over or meiotic gene recombination. Class 9 Science Exploration New Book All Chapter Solution Revise, Reflect, Refine Chapter ...
