What reading level is Proceedings International Conference On Plant Breeding And Hybridization 1902 book?
To quickly assess the difficulty of the text, read a short excerpt:
In high emasculation the corolla and anthers were removed with tweezers, and the calyx was not disturbed. In low emasculation the calyx, corolla and stamens were removed by cutting through the blossom just at the base of the sepals, being careful not to injure the pistils. This necessitates very careful work and cutting entirely around the blossom. Low emasculation has the advantage that it can be done much more expeditiously than high emascula- tion, and if the results of pollination were sati...sfactory would be a decided advantage. But in fifty-nine blossoms emasculated low in five different varie- ties of apples only seven fruits set, or less than 2 per cent. ; and in eighty- eight blossoms emasculated high twenty-three set fruit, or slightly over 26 per cent. The results were even more pronounced in the Wealthy apple. Fifty blossoms emasculated high and pollinated with Ben Davis pollen set eleven fruits, or 22 per cent. Twenty-five emasculated low set only one fruit, or 4 per cent.
POLLINATION AT TIME OF EMASCULATION.
