α-Tomatine was not highly phytotoxic and slightly inhibited the stem elongation (7 to 13%) when applied as a spray to etiolated 4-day-old seedlings of sesbania [Sesbania exaltata (Raf.) Rybd.], sicklepod (Senna obtusifolia L.), mungbean (Vigna radiata L.), wheat (Triticum aestivum L.) and sorghum (Sorghum vulgare L.). Tomatidine had less effect on stem elongation than tomatine and reduced the e...

The objective of this investigation was to evaluate the toxicity to termites and the leaching stability of copper compounds derived from triand dioctylamineboric acid complexes for protecting wood against termite at tack . Water inso luble copper Nmethyldioctylamine or copper N-dioctylamine and copper borate were precipitated in wood by the reaction of N-methyldioctylamine or N-dioctylamine-bor...

Individual trees of giant sequoia (Sequoia gigantea [Lindl.] Decne.) have demonstrated a capacity to attain both a long life and very large size. It is not uncommon to find old-growth giant sequoia trees in their native range that are 1,500 years old and over 15 feet in diameter at breast height. The ability of individual giant sequoia trees to survive over such long periods of time has often b...
