The effect of ionizing radiation on germination of seed and growth of seedlings of Scots pine was investigated. Higher radioresistance of seed originating from the highland region was established. No difference was found in the investigated seed samples in the content of cysteine and content and composition of the chloroform-soluble fraction. Differences in compounds contained in the chloroform-soluble fraction and in the rate of phosphorus uptake were found in young seedlings of different provenience. They possibly are related to the difference in the ability of seedlings to regenerate the postirradiation damage.

Background: Availability of quality planting materials is the major impediment in extension of cultivation of low chilling peach in northern plans. Plum suckers are mostly used as rootstocks for raising peach; however nematode infestation is a major problem. Seeds of all peach cultivars do not germinate under subtropical climate of plains of Northern India. Hence, an experiment was carried out at ICAR-CISH, Lucknow on seed germination and subsequent growth of seedlings of low chilling peaches.Methods: Fully mature seeds of peach cv. Florda Prince, Pant Peach 1 and Sharbati were collected during June. Some of the seeds were sown direct in-situ during 1st week of December and remaining seeds were sown in the field after 2 months of stratification in the refrigerator at 7-8°C.Result: Stratification had significant effect on seed germination and late matured peach cv. ‘Sharbati’ exhibited higher seed germination. Good linear seedling growth and maximum percentage of buddable seedlings was found in stratified sown seeds of ‘Sharbati’ peach. Thus the study indicated that harvesting of ‘Sharbati’ and ‘Pant Peach-1’ seeds can be done during June and pre-sown stratification is necessary for better germination and growth of seedlings under subtropical climate of Lucknow.

The results of studies carried out in the Pravdinsky nursery of the Pushkin Forestry Technical Colledge in the Moscow Region and in the laboratory of the department «Forest cultures, selection and dendrology» at the ВMSTU (Mytishchi branch) since May 2015 untill September 2019 are presented. The results of the study confirmed the significant advantage of experimental indicators over the control. Thus, the treatment of seeds and two-year-old seedlings of Scots pine with a low-frequency electromagnetic field using the POSEP technology, in general had a positive effect not only on their survival rate and biometric parameters, but also on their anatomical structure. Based on the results of the studies, it can be ststed that the POSEP technology is an effective method of physical impact on the survival rate and growth increase of Scots pine seedlings.

Inoculation of rhizobacteria in seeds and plants has been documented as a stimulant and promoter of germination and growth of agricultural crops, but there is little information on native forest species. Therefore, the present study aims to evaluate the potential of Azospirillum brasilense inoculation in the germination of seeds and initial growth of seedlings of native forest species. The following experiments were carried out: (I) germination of seeds in germination chamber, and (II) initial growth of seedlings in nursery, both with four forest species (Cassia leptophylla, Lafoensia pacari, Mimosa flocculosa and Schinus terebinthifolius). For the four species, in both experiments, two treatments were used: inoculation of seeds with concentrated solution of A. brasilense and no inoculation of seeds (control). Physiological aspects of seed germination and seedling vigor were evaluated in the first experiment (germination speed, and length and dry weight of seedlings), and seedling growth was evaluated in the second experiment (height, collar diameter and dry weight of seedlings). Inoculation of A. brasilense in seeds of C. leptophylla, L. pacari, M. flocculosa and S. terebinthifolius did not promote beneficial or promising results for seed germination and initial growth of seedlings, so its use to produce seedlings of these species is not recommended.
