Bhagavai 7:7:150-154
of the machine with the plant, Mr. Vogel, touching the plants with his palms, started to fill his mind with the feelings of love and friendliness towards the plant. Mr. Vogel found that the machine connected with the plant produced a graph on paper. He repeated the same experiment several times and obtained almost the similar graph everytime. When Prof. Vogel presented his findings in a conference of the botanists, some of them showed interest in his experiments. One of them Dr. Silem Jones, himself perfomed the same experiments with his own hands and obtained satisfactory results. Once, when Jones entered into Prof. Vogel's laboratory, the plant ceased to give the vibrations at all. Vogel asked Jones what he was thinking about. Jones said that he was just comparing the condition of his own plant with that of Vogel's and found that the former was more flourishing than the latter. Vogel's plant did not give any vibration for fifteen days. The question arose as to although the machine was in order, why it did not record any vibrations. Replying to this question, Prof. Vogel said that the feelings which Jones had brought in his mind about Vogel's plant in the form of contempt by considering it inferior to his own plant, had hurt immensely the feelings of Vogel's plant, and for this reason, it had denied to communicate or to express to him.
The sensitivity of the plants has also been proved by the renowned botanist of New York, Mr. Cleve Backster. He used galvenometer to record the vibrations of the plant and used pen in place of needle. First, he dropped a live leaf, without detaching it from the branch, into the cup of hot coffee, wanted to know the reaction thereof, but there was no reaction registred. After rethinking, he performed another experiment in which he, made a decision to burn a leaf with a match-stick. No sooner, he touched the match-stick for holding it, than the galvanometer started recording rapidly the vibrations of the plant (to show its reaction). He repeated the same experiment several times and preserved all the graphs. The same experiment was repeated twenty-five times on different kinds of plants which were brought from different places of the country. The effect of thoughts on different plants were recorded through different galvanometers. The result was the same as earlier. These vibrations were transformed in the form of sound vibrations. When these sounds were heard, they implied different kinds of feelings (emotions); some were of fear, some of pleasure, some of delight, while some of joy.
Besides being terrified, being able to express the feeling of gladness or pleasure and being able to recognise the enemy, the plants, trees etc. are also able to experience heat and cold. They also become thirsty. This discovery is made by the renowed Russian botanist Leonid A. Panishkin and Cherio Monav. They connected a very sophisticated machine with a plant of beans. Whenever the piant needed water, it would give indication through a special proces to the machine, the plant was given water through a special process. It was observed that plant accepted water for the first two minutes, and after that it expressed its unwillingness to have more water. After an hour, again
the plant gave a signal for having water." 5. Ibid., "Till now, it was thought that there was no sensitivity-system in plants and trees, as they do
not possess the nerves which are available to animals. But, according to a study made in the Norwegian Research Park situated in East England, when the worms used to bite the leaf of the tomato plant, the leaf immediately would send an electrical warning message to the whole plant. No sooner the rest of the unbitten leaves receive the message, than they would start secreting a protective (immunitive) chemical substance, which would be difficult (for the worms) to digest.
This study is made jointly by the scientists of East Eglia University and John Inns Centre with the scientists of New Zealand.
Prof. Keith Roberts, the Head of the Department of the Celluar Science at John Inns Centre, says that the plants use the electrical message in the same way as the animals and birds do in their neurons. In animals, the waves of the message travel rapidly between the body and brain; whereas in the case of the plants, these messages travel at a snail's speed.
A team of the British Scientists is still busy with the reasearch to find out as to which cells in the plants are responsible for production of these electrical messages and how automatically they are produced when the plant is injured."
