Aim: The study aims to develop an advanced non-destructive method to estimate the plant growth rate of
tissue culture propagated banana plantlets during primary hardening phase inside the greenhouse using
Bootstrapped Artificial Neural Network (BANN).
Methodology: Both non-destructive growth parameters like plant height, girth, number of leaves, leaf
length and leaf breadth, and destructive growth parameters like number of roots, longest root length, fresh
and dry weight were measured periodically on selected plants of one week to nine week old which were kept
in greenhouse at ICAR-National Research Centre for banana. In addition to plant growth parameters,
greenhouse temperature, radiation and carbon dioxide concentration were also recorded daily. The
experimental data obtained using destructive measurements were recorded on a small sample of size n, and
hence re-sampling for bootstrap involves n repeated trials of simple random sampling with replacement.
These sets of bootstrap samples were finally used as input to develop neural model using a novel
methodology of bootstrap re-sampling based artificial neural network (ANN) for studying the progress of
plant ontogeny.
Results: The growth estimation analysis of plants in terms of its leaf area and biomass production was
performed without physically handling the test plants using bootstrap ANN. The notion of prediction
performance is validated through statistical indices namely Nash and Sutcliffe efficiency coefficient, root
means square error and mean absolute error. The approximate estimates of mean relative growth and net
assimilation rate of plants were 0.036 and 0.027, and the corresponding variance were 1.5 x 10-6 and 2.12 x
10-6, respectively.Interpretation: Based on the non-destructive plant growth observations, the measures to increase the overall plant growth can be significantly predicted well in advance. This projected plant growth statistics at an early stage of hardening serves as an essential component in planning and evaluation of investments on protected structure to improve the productivity and profitability of banana tissue culture industry.
