Abstract

The effect of water stress and some antitranspirants on the survival, growth and dry matter production of Grevillea robusta A. Cunn. were studied under controlled laboratory conditions. In general, the survival percentage, height of plants, number of leaves per plant, no. of branches per plants, fresh and dry mass of ischolar_mains, stem, branches and leaves decreased with increasing water stress irrespective to control (untreated) as wen as in aU antitranspirant treatments. However, the effect was more prominent under antitranspirant treatments. Commonly the decrease in the said parameter was more sharp from daily to weekJy watering interval than to fortnightly interval. No seedlings could survival under monthly watering interval.

Abstract

Leafy soft-wood cuttings and non-leafy shoot cuttings of Bhanjira (Perilla frutescens Linn.) are easy to ischolar_main. Treatment with IAA, IBA, IPA, and NAA caused promotion of ischolar_maining, increased shoot growth and stimulated flowering also. The results indicate that clonal crops can be raised using shoot cuttings and that auxin has the potential of being used for yield improvement in this species.
